So far there have been no studies focusing on the prevalence of a wide spectrum of oral mucosal lesions (OML) in patients with dermatologic diseases. This is noteworthy as skin lesions are strongly associated with oral lesions and could easily be neglected by dentists. This study aimed to estimate the frequency and socio-behavioural correlates of OML in skin diseased patients attending outpatient's facility of Khartoum Teaching Hospital - Dermatology Clinic, Sudan.
A cross-sectional hospital-based study was conducted in Khartoum from October 2008 to January 2009. A total of 588 patients (mean age 37.2 ± 16 years, 50.3% females) completed an oral examination and a personal interview of which 544 patients (mean age 37.1 ± 15.9 years, 50% females) with confirmed skin disease diagnosis were included for further analyses. OML were recorded using the World Health Organization criteria (WHO). Biopsy and smear were used as adjuvant techniques for confirmation. Data were analysed using the Statistical Package for Social Science (Version 15.0.1). Cross tabulation and Chi-square with Fisher's exact test were used.
A total of 438 OML were registered in 315 (57.9%, males: 54.6% versus females: 45.6%, p < 0.05) skin diseased patients. Thus, a certain number of patients had more than one type of OML. Tongue lesions were the most frequently diagnosed OML (23.3%), followed in descending order by white lesions (19.1%), red and blue lesions (11%) and vesiculobullous diseases (6%). OML in various skin diseases were; vesiculobullous reaction pattern (72.2%), lichenoid reaction pattern (60.5%), infectious lesions (56.5%), psoriasiform reaction pattern (56.7%), and spongiotic reaction pattern (46.8%). Presence of OML in skin diseased patients was most frequent in older age groups (62.4% older versus 52.7% younger, p < 0.05), in males (63.2% males versus 52.6% females, p < 0.05), patients with a systemic disease (65.2% with systemic versus 51.9% without systemic disease, p < 0.05) and among current users of smokeless tobacco (toombak) (77% current use versus 54.8% no use, p < 0.00).
OML were frequently diagnosed in skin diseased patients and varied systematically with age, gender, systemic condition and use of toombak. The high prevalence of OML emphasizes the importance of routine examination of oral mucosa in a dermatology clinic.
Generic and condition-specific (CS) oral-health-related quality-of-life (OHRQoL) instruments assess the impacts of general oral conditions and specific oral diseases. Focusing schoolchildren from Arusha and Dar es Salaam, in Tanzania, this study compared the discriminative ability of the generic Child OIDP with respect to dental caries and periodontal problems across the study sites. Secondly, the discriminative ability of the generic-and the CS Child OIDP attributed to dental caries, periodontal problems and malocclusion was compared with respect to various oral conditions as part of a construct validation.
In Arusha, 1077 school children (mean age 14.9 years, range 12-17 years) and 1601 school children in Dar es Salaam (mean age 13.0 years, range 12-14 years) underwent oral clinical examinations and completed the Kiswahili version of the generic and CS Child-OIDP inventories. The discriminative ability was assessed as differences in overall mean and prevalence scores between groups, corresponding effect sizes and odd ratios, OR.
The differences in the prevalence scores and the overall mean generic Child-OIDP scores were significant between the groups with (DMFT > 0) and without (DMFT = 0) caries experience and with (simplified oral hygiene index [OHI-S] > 1) and without periodontal problems (OHI-S ≤ 1) in Arusha and Dar es Salaam. In Dar es Salaam, differences in the generic and CS Child-OIDP scores were observed between the groups with and without dental caries, differences in the generic Child-OIDP scores were observed between the groups with and without periodontal problems, and differences in the CS Child-OIDP scores were observed between malocclusion groups. The adjusted OR for the association between dental caries and the CS Child-OIDP score attributed to dental caries was 5.4. The adjusted OR for the association between malocclusion and CS Child-OIDP attributed to malocclusion varied from 8.8 to 2.5.
The generic Child-OIDP discriminated equally well between children with and without dental caries and periodontal problems across socio-culturally different study sites. Compared with its generic form, the CS Child-OIDP discriminated most strongly between children with and without dental caries and malocclusion. The CS Child OIDP attributed to dental caries and malocclusion seems to be better suited to support clinical indicators when estimating oral health needs among school children in Tanzania.
Oral health-related quality of life, OHRQoL, among elderly is an important concern for the health and welfare policy in Norway and Sweden. The aim of the study was to assess reproducibility, longitudinal validity and responsiveness of the OIDP frequency score. Whether the temporal relationship between tooth loss and OIDP varied by country of residence was also investigated.
In 2007 and 2012, all inhabitants born in 1942 in three and two counties of Norway and Sweden were invited to participate in a self-administered questionnaire survey. In Norway the response rates were 58.0% (4211/7248) and 54.5% (3733/6841) in 2007 and 2012. Corresponding figures in Sweden were 73.1% (6078/8313) and 72.2% (5697/7889), respectively.
Reproducibility of the OIDP in terms of intra-class correlation coefficient (ICC) was 0.73 in Norway and 0.77 in Sweden. The mean change scores for OIDP were predominantly negative among those who worsened, zero in those who did not change and positive in participants who improved change scores of the reference variables; self-reported oral health and tooth loss. General Linear Models (GLM) repeated measures revealed significant interactions between OIDP and change scores of the reference variables (p < 0.05). Stratified analysis revealed that the mean OIDP frequency score worsened in participants who became dissatisfied- and improved in participants who became satisfied with oral health. Compared to participants who maintained all teeth, those who lost teeth were more likely to experience improvement and worsening of OIDP across both countries. The two-way interaction between country and tooth loss was not statistically significant.
Changes in OIDP at the individual level were more pronounced than the percentage distribution of OIDP at each point in time would suggest. The OIDP frequency score showed promising evaluative properties in terms of acceptable longitudinal validity, responsiveness and reproducibility among older people in Norway and Sweden. This suggests that the OIDP instrument is able to detect change in the oral health status that occurred over the 5 year period investigated. Norwegian elderly were more likely to report worsening in OIDP than their Swedish counterparts. Disease prevention should be at focus when formulating the health policy for older people.

The aim of the study was to evaluate the prevalence of oral mucosal lesions (OML) in adult patients reporting to the dental outpatient department at the Institute of Dental Studies and Technologies, Modinagar, Uttar Pradesh, India. The purpose was to determine the priorities in oral health education, preventive measures, and identify the group in urgent need of treatment.
Materials and Methods:
The study was conducted over a period of 6 months in 2010, when 8866 subjects were offered structured interviews and standardized extraoral and intraoral examinations according to the World Health Organization (WHO) guidelines.
Overall prevalence of OML was 1736 (16.8%), the most prevalent being smoker's palate (10.44%) followed by leukoplakia (2.83%), oral submucous fibrosis (1.97%), oral candidiasis (1.61%), recurrent aphthous stomatitis (1.53%), oral lichen planus (0.8%) and others (0.78%). The highest prevalence of the tobacco habit in both forms was recorded in the group aged 40–44 yearsand those aged between 60 and 64 years who wore dentures. Lesions were most prevalent in those aged 40–44 years with a significant predominance of males at 3:1 (M = 12.6% and F = 4.3%). Patients who consumed tobacco in any form or wore dentures had a significantly higher prevalence of OML (P < 0.001). The highest number of lesions were on the palate (59.7%) followed by buccal mucosa (19.9%). Various normal mucosal variants were recorded. Fordyce's granules (0.13%), fissured tongue (3.3%), leukoedema (1.47%), and lingual varices (2.73%) were also recorded. The tongue showed the highest number of variants (64.4%). Patients were grouped according to the treatment needed under the WHO criteria. One hundred and ninety-seven patients were given oral hygiene instructions only, whereas 1422 patients were advised on change of habit and a follow-up and 674 patients needed definitive treatment.
This study thus highlights diagnostic criteria, multifactorial risk factors to make standard measurements of OML a basis for planning and evaluating oral health programs for data collection.

Diabetes mellitus is associated with a greater likelihood of developing certain oral mucosal disorders. This study was aimed at assessing the prevalence of oral mucosal lesions (OMLs) in patients with type 2 diabetes (DM2) and to investigate the association of such lesions with metabolic control of the disease.
This cross-sectional study involved 391 patients with DM2 and 391 non-diabetic control subjects. Demographic information and data on the duration and type of diabetes, glycosylated hemoglobin (HbA1c) values, medical history, and current use of medication were obtained from medical records. Detailed oral examination was performed in accordance with international criteria.
The prevalence of OMLs was significantly higher among diabetic patients (45.5%) than among control subjects (38.4%) (P = 0.042). Patients with diabetes had a higher prevalence of geographic tongue (GT) (P = 0.017), denture stomatitis (P = 0.018), and angular cheilitis (P = 0.006) than controls. Overall, diabetic patients with poor metabolic control had a significantly higher prevalence of OMLs and xerostomia than patients with moderately and well-controlled disease (P < 0.05).
The prevalence of OMLs was significantly higher in diabetic patients than in control subjects. Higher occurrence of OMLs was significantly associated with poor metabolic control.

Epidemiologic researches about oral mucosal lesions have been performed in different populations. But, in dermatology outpatients, oral mucosal lesions have not been investigated previously.
We aimed to determine the prevalence of oral mucosal lesions among dermatology outpatients and the relationship between OML and smoking, alcohol intake, denture and dental filling use and skin diseases.
Randomly selected 1041 dermatology outpatients were examined for dermatological diseases and oral mucosal lesions. All of the patients were questioned about smoking, alcohol intake, denture and dental filling use.
In 235 patients, oral mucosal lesions were recorded. 268 (25.7%) of the patients had history of smoking, 42 (4%) drinking alcohol and 180 (17.3%) denture and dental filling. 32 (64%) of the smokers, 54 (30%) of denture users and 10 (23.8%) alcohol consumers had at least one OML. Age and smoking were found as significant risk factors for oral mucosal lesions. Fissured tongue was the most common oral lesion and it was seen significantly higher in patients with denture. Smoking was risk factor for coated tongue and linea alba.
Oral mucosa should be examined carefully even if the patients do not attend with the complaint of oral lesions, especially in elderly patients, smokers and denture users.

The aim of this study was to assess the prevalence of oral mucosal lesions (OMLs) and dental caries and to evaluate oral health practices among institutionalized orphan-children in Sana’a city, Yemen.
Subjects and Methods:
A sample of 202 institutionalized male-orphan-children in the main orphanage in Sana’a city, were matched to 202 non-orphan schoolchildren. Clinical examination included assessment of OMLs based on standard international diagnostic criteria and evaluation of dental status using the Decayed/decayed, Missed/missed and Filled/filled (DMFT/dmft) index according to World Health Organization recommendations. Demographic data and oral hygiene practices were obtained by interviewing each subject using special questionnaire form.
Majority of children were in the 12-15 year age group. Nine types of lesions were reported among orphans; the most common lesions were fissured tongue (24.3%), herpes labialis (7.9%) and traumatic ulcers (2.5%). The occurrence of herpes labialis was found to be significantly higher in orphans than in controls (P < 0.01). The prevalence of dental caries was insignificantly lower among the orphans (84.7%) compared with the non-orphans (89.61%; P = 0.136). The mean dmft score was significantly lower in orphans than in controls (2.28 vs. 3.82; P = 0.001).
The institutionalized children in this orphanage had a high prevalence of OMLs but low prevalence of dental caries, though they revealed poor oral hygiene practices. Effective oral health promotion strategies need to be implemented to improve the oral health and oral health practices of children living in orphanages.

There is a need for studies evaluating oral health related quality of life (OHRQoL) of children in developing countries.
to assess the psychometric properties, prevalence and perceived causes of the child version of oral impact on daily performance inventory (Child-OIDP) among school children in two socio-demographically different districts of Tanzania. Socio-behavioral and clinical correlates of children's OHRQoL were also investigated.
One thousand six hundred and one children (mean age 13 yr, 60.5% girls) attending 16 (urban and rural) primary schools in Kinondoni and Temeke districts completed a survey instrument in face to face interviews and participated in a full mouth clinical examination. The survey instrument was designed to measure a Kiswahili translated and culturally adapted Child-OIDP frequency score, global oral health indicators and socio-demographic factors.
The Kiswahili version of the Child-OIDP inventory preserved the overall concept of the original English version and revealed good reliability in terms of Cronbach's alpha coefficient of 0.77 (Kinondoni: 0.62, Temeke: 0.76). Weighted Kappa scores from a test-retest were 1.0 and 0.8 in Kinondoni and Temeke, respectively. Validity was supported in that the OIDP scores varied systematically and in the expected direction with self-reported oral health measures and socio-behavioral indicators. Confirmatory factor analyses, CFA, confirmed three dimensions identified initially by Principle Component Analysis within the OIDP item pool. A total of 28.6% of the participants had at least one oral impact. The area specific rates for Kinondoni and Temeke were 18.5% and 45.5%. The most frequently reported impacts were problems eating and cleaning teeth, and the most frequently reported cause of impacts were toothache, ulcer in mouth and position of teeth.
This study showed that the Kiswahili version of the Child-OIDP was applicable for use among schoolchildren in Tanzania.
With aging, the oral mucosa becomes more susceptible to external stimuli. The aims of this study were to obtain baseline data on the prevalence of oral mucosal lesions (OMLs) in a population of elderly Yemeni patients and to investigate differences in the presentation of these findings in relation to age, gender, education level, and the wearing of dentures.
Patients and Methods:
The prevalence of OMLs was assessed by clinical examination of a sample of 310 elderly Yemeni patients aged 60 years and older. A single examiner performed detailed oral examinations of the oral cavity according to international criteria and the World Health Organization codes.
The overall prevalence of OMLs was 77.1%, with a significant difference (P < 0.05) between men (80.3%) and women (69.6%). The prevalence rate of OMLs indicated a significant decrease with advancing age. The most frequently observed lesions were fissured tongue (34.2%), benign tumors (17.1%), hairy tongue (16.5%), and qat-induced white lesions (12.6%). Hairy tongue, qat-induced white lesions, and shammah keratosis were associated with men (P < 0.01, P < 0.05, and P < 0.05, respectively), whereas geographic tongue was associated with women (P < 0.05). The presence of one or more lesions was significantly associated with low education level (P < 0.05). Certain OMLs showed a significant association with smoking and qat chewing (P < 0.05). No association was found between the occurrence of OMLs and denture wearing (P > 0.05).
The present study has shown a high prevalence of oral lesions among Yemeni elders.

Information on oral health-related quality of life, in addition to clinical measures, is essential for healthcare policy makers to promote oral health resources and address oral health needs.
This paper aimed at evaluating the psychometric properties of the Arabic version of Child-OIDP, estimating the prevalence, severity and causes of oral impacts on daily performances in 12-year-old public and private school attendees in Khartoum State and to identify socio-demographic and clinical correlates of oral impacts as assessed by the Child-OIDP inventory.
The Child-OIDP questionnaire was translated into Arabic was administered to a representative sample of 1109 schoolchildren in Khartoum state. Clinical measures employed in this study included DMFT index, Gingival index, Plaque index and Dean's index. A food frequency questionnaire was used to study the sugar-sweetened snack consumption.
The instrument showed acceptable psychometric properties and is considered as a valid, reliable (Cronbach's alpha 0.73) and practical inventory for use in this population. An impact was reported by 54.6% of the schoolchildren. The highest impact was reported on eating (35.5%) followed by cleaning (28.3%) and the lowest impacts were on speaking (8.6%) and social contact (8.7%). Problems which contributed to all eight impacts were toothache, sensitive teeth, exfoliating teeth, swollen gums and bad breath. Toothache was the most frequently associated cause of almost all impacts in both private and public school attendees. After adjusting for confounders in the 3 multiple variable regression models (whole sample, public and private school attendees), active caries maintained a significant association with the whole sample (OR 2.0 95% CI 1.4-2.6) and public school attendees (OR 3.5 95% CI 2.1-5.6), and higher SES was associated with only public school attendees' Child-OIDP (OR 1.9 95% 1.1-3.1).
This study showed that the Arabic version of the Child-OIDP was applicable for use among schoolchildren in Khartoum. Despite the low prevalence of the dental caries pathology (24%), a significant relationship, with an average moderate intensity was found with OHRQoL. Focus in this population should be on oral health education, improving knowledge of the prospective treatment opportunities and provision of such services.
At present, there is no evidence on whether using condition-specific Oral Health-Related Quality of Life (OHRQoL) measures provides more reliable information than generic measures for needs assessment. Therefore, the objective was to assess the discriminative ability of one generic and one condition-specific OHRQoL measure, namely, respectively, the short form of the Oral Health Impact Profile (OHIP-14) and the Condition-Specific form of the Oral Impacts on Daily Performances (CS-OIDP) attributed to malocclusion, between adolescents with and without normative need for orthodontic treatment.
200 16–17-year-old adolescents were randomly selected from 957 schoolchildren attending a Sixth Form College in London, United Kingdom. The impact of their oral conditions on quality of life during the last 6 months was assessed using two OHRQoL measures; OHIP-14 and OIDP. Adolescents were also examined for normative orthodontic treatment need using the Index of Orthodontic Treatment Need (IOTN) and the Dental Aesthetic Index (DAI). Discriminative ability was assessed comparing the overall scores and prevalence of oral impacts, calculated using each OHRQoL measure, between adolescents with and without normative need. Using the prevalence of oral impacts allowed adjusting for covariates.
There were significant differences in overall scores for CS-OIDP attributed to malocclusion between adolescents with and without normative need for orthodontic treatment when IOTN or DAI were used to define need (p = 0.029 or 0.011 respectively), and in overall scores for OHIP-14 when DAI, but not IOTN was used to define need (p = 0.029 and 0.080 respectively). For the prevalence of impacts, only the prevalence of CS-OIDP attributed to malocclusion differed significantly between adolescents with and without normative need, even after adjusting for covariates (p = 0.017 and 0.049 using IOTN and DAI to define need).
CS-OIDP attributed to malocclusion was better able than OHIP-14 to discriminate between adolescents with and without normative needs for orthodontic treatment.
This study examined whether oral health-related quality of life (OHRQoL) is associated with nutritional status in patients treated for oral cancer.
A cross-sectional study was carried out on with patients treated for oral cancer at least 6 months after treatment. OHRQoL was measured using two questionnaires: Oral Impacts on Daily Performances (OIDP) and Oral Health Impact Profile (OHIP-14); malnutrition risk was assessed through the Mini Nutritional Assessment (MNA). Multivariable regression models assessed the association between the outcomes (OIDP and OHIP-14) and the exposure (MNA), adjusting for sex, age, clinical stage, social class, date of treatment completion, and functional tooth units.
The final simple included 133 patients, 22.6 % of which were malnourished or at risk of malnutrition. More than 95 % of patients reported a negative impact on the OHRQoL for both measures used. Patients with malnutrition or risk of malnutrition had significantly worse OHRQoL than those with no malnutrition, even after adjusting for clinical and socioeconomic data (ß-coefficient = 8.37 (95 % confidence interval (CI) 1.42–15.32) with the OIDP and ß-coefficient = 2.08 (95 % CI 0.70–3.46) with the OHIP-14).
Being malnourished or at risk of malnutrition is an important longer-term determinant of worse OHRQoL among patients treated for oral cancer.

Health-related quality of life (HRQoL) is gaining importance as a valuable outcome measure in oral cancer area. The aim of this study was to assess the general and oral HRQoL of oral and oropharyngeal cancer patients 6 or more months after treatment and compare them with a population free from this disease.
A cross-sectional study was carried out with patients treated for oral cancer at least 6 months post-treatment and a gender and age group matched control group. HRQoL was measured with the 12-Item Short Form Health Survey (SF-12); oral HRQoL (OHRQoL) was evaluated using the Oral Health Impact Profile (OHIP-14) and the Oral Impacts on Daily Performances (OIDP). Multivariable regression models assessed the association between the outcomes (SF-12, OHIP-14 and OIDP) and the exposure (patients versus controls), adjusting for sex, age, social class, functional tooth units and presence of illness.
For patients (n = 142) and controls (n = 142), 64.1% were males. The mean age was 65.2 (standard deviation (sd): 12.9) years in patients and 67.5 (sd: 13.7) years in controls. Patients had worse SF-12 Physical Component Summary scores than controls even in fully the adjusted model [β-coefficient = −0.11 (95% CI: −5.12-(−0.16)]. The differences in SF-12 Mental Component Summary were not statistically significant. Regarding OHRQoL patients had 11.63 (95% CI: 6.77-20.01) higher odds for the OHIP-14 and 21.26 (95% CI: 11.54-39.13) higher odds for OIDP of being in a worse category of OHRQoL compared to controls in the fully adjusted model.
At least 6 months after treatment, oral cancer patients had worse OHRQoL, worse physical HRQoL and similar psychological HRQoL than the general population.

Objectives: This study aimed to assess the prevalence of oral mucosal lesions (OMLs) in patients attending outpatient dental clinics in Sana`a university, Yemen, and to evaluate the association of such lesions with age, gender, and oral habits.
Materials and Methods: This cross-sectional study included 409 subjects (272 males, 137 females, age: 15-86 years). Detailed clinical examination was performed in accordance with international criteria. Patient history included age, gender, education, denture wearing and risk habits (tobacco use and qat chewing). Data were analyzed using SPSS 19.00.
Results: The prevalence of OMLs was 58.4% with a significant difference between men (63.6%) and women (48.2%; P < 0.05). The most common lesions were fissured tongue (37.2%), hairy tongue (15.9%), tumors and tumor-like lesions (9.8%), qat-induced white lesions (9.3%) and racial pigmentation (5.9%). Overall OMLs prevalence was linked to risk habits and age; qat chewing was statistically significant risk factor for having fissured tongue (OR: 1.77), hairy tongue (OR: 2.74), and white lesions (OR: 2.39) (P < 0.05). Cigarette smoking was statistically significant risk factor for having hairy tongue (OR: 2.82), white lesions (OR: 3.60) and tumors and tumor-like lesions (OR: 2.91) (P < 0.01). The increase in age was statistically significant risk factor for having tumors and tumor-like lesions (OR: 1.04; P < 0.001).
Conclusions: The current results indicate that the occurrence of OMLs among Yemeni adults is high and emphasize that risk habits and age have some relationship with the presence of OMLs.

Assessing oral health related quality of life impact of mouth in adolescents is a relatively ignored area in dental research. This study aimed to examine reliability and validity of an abbreviated version of the oral impact of daily performance (OIDP) questionnaire and to analyse the interrelationship among OIDP scores, socio-demographic characteristics and oral health status in Uganda.
1146 adolescents (mean age 15.8, response rate 87%) attending secondary schools in Kampala (urban) and Lira (rural) completed a survey instrument designed to measure subjective oral health indicators including the eight-item OIDP frequency scores. A clinical examination was conducted among 372 students (mean age 16.3, response rate 72%) and caries was assessed following the World Health Organisation criteria (1997).
62% of the students experienced at least one oral impact during the 6 months preceding the survey. Cronbach's alpha for the OIDP frequency items was 0.91 and the corrected item-total correlation ranged from 0.62 to 0.75. Discriminant and construct validity were demonstrated in that the OIDP scores varied systematically in the expected direction with missing teeth and self-report indicators of oral health status, respectively. Socio-demographics and dental attendance did not predict OIDP through interaction with clinical indicators but varied systematically and independently with OIDP frequency scores in the multivariate analysis.
the OIDP frequency score have acceptable psychometric properties in the context of an oral health survey among Ugandan adolescents. Some evidence of the importance of social and personal characteristics in shaping adolescents' responses to oral disorders was provided.

Good oral health in older residents of nursing homes is important for general health and quality of life. Very few studies have assessed how oral symptoms affect residents’ quality of life.
To assess the clinical and subjective oral health, including oral health related quality of life (OHRQoL), and the association of oral symptoms with OHRQoL in older people residing in nursing homes in Islington, London.
Overall, 325 residents from nine nursing homes were clinically examined and 180 residents were interviewed to assess their oral symptoms and their OHRQoL using the OIDP measure. Managers and carers working in the homes were also interviewed.
Almost two thirds of the sample were dentate (64.5 %). 61.3 % of dentate and 50.9 % of edentate residents reported problems such as dry mouth, sore cracked lips, broken teeth and toothache and ill-fitting dentures. Oral health impacted considerably upon resident’s OHRQoL; 20.2 % of dentate and 30.9 % of edentate reported at least one oral impact in the past 6 months. Sensitive teeth, toothache, bleeding gums, dry mouth and loose natural teeth among the dentate and loose or ill-fitting dentures among the edentate were strongly associated with higher prevalence of oral impacts even after adjusting for demographic and socio-economic factors, and for the number of teeth (dentate only).
The burden of oral conditions was considerable. Oral symptoms were very common and were strongly associated with residents’ worse OHRQoL. Health promotion programmes are important to help residents maintain an acceptable level of oral health and function.

Few studies have investigated the relationships between HIV-related knowledge, fear of contagion in dental environments and Oral Impacts on Daily Performance (OIDP) among dental patients. Our objectives were to investigate the associations between HIV-related knowledge and fear of contagion in dental environments and OIDP among dental patients, and to evaluate whether those associations were modified by the frequency of dental service attendance.
A total of 1262 patients (mean age 30.7 years, 56.5% females) were recruited from the Khartoum Dental Teaching Hospital and the University of Science and Technology during March–July 2008. The participants underwent a full-mouth oral clinical examination and completed an interview in a face-to-face setting.
Of the study participants, 41.4% had visited a dentist at least twice during the last 2 years, 96.2% had caries experience (DT > 0) and 79.1% reported oral impacts (OIDP > 0). The most frequently reported oral impacts were problems eating, sleeping and cleaning teeth. In total, 26.3% of the participants had HIV transmission knowledge, 75.6% knew people with HIV/AIDS and 58.7% perceived a high risk of cross-infection in dental environments. After adjusting for sociodemographic characteristics, frequency of dental service attendance and caries experience, patients who had high HIV-related information exposure, a positive attitude toward people with HIV/AIDS and a high perceived risk of cross-infection were more likely to report oral impacts, whereas patients who knew people with HIV/AIDS were less likely to report oral impacts. The association between OIDP and HIV transmission knowledge was modified by frequency of dental service attendance.
Dental patients who were informed about HIV and had a high HIV/AIDS risk perception were more likely to report impaired oral health-related quality of life than their less informed counterparts and those who perceived a low risk of contagion. The effect of HIV transmission knowledge on oral impacts was influenced by frequency of dental service attendance.

Data obtained from oral health surveys are very important for identifying disease-susceptible groups and for developing dental care and prevention programs. So, the purpose of the current article was to investigate the prevalence of oral mucosa lesions (OMLs) in a population of Brazilian police.
Material and Methods
Interviews and oral cavity examinations were performed on a sample of 395 police officers who were randomly selected by the calibrated researcher. The number of individuals was obtained by a sample calculation using the finite population correction. The diagnostic criteria were based on the WHO (1997) criteria and adapted to Brazilian surveys.
In total, 8.61% of the population presented some OML. Traumatic injuries and benign migratory glossitis (BMG) were the most prevalent lesions.
The prevalence of potentially malignant disorders was lower than among the Brazilian population.The most prevalent lesion among the police officers was related to trauma. Patients dissatisfied with oral health had a higher risk of presenting OMLs.

To determine the impact of oral diseases on everyday life, measures of oral quality of life are needed. In complementing traditional disease-based measures, they assess the need for oral care to evaluate oral health care programs and management of treatment. To assess the reliability and validity of the Oral Impact of Daily Performance (OIDP) and the short-form Oral Health Impact Profile (OHIP-14) among high school students in Xi’an, the capital of Shanxi province, China.
Cross-sectional one-stage stratified random cluster sample using high schools as the primary sampling unit. Students completed self-administered questionnaires at school. The survey included the OHIP-14 and OIDP inventories, translated and culturally adapted for China, and global oral health and socio-behavioral measures.
A total of 5,608 students participated in the study, with a 93% response rate (mean age 17.2, SD 0.8, 52% females, 45.3% urban residents).The proportion experiencing at least one impact (at any frequency) during the previous six months was 62.9% for the OHIP-14 and 45.8% for the OIDP. Cronbach’s alpha measured internal consistency at 0.85 for OHIP-14 and 0.75 for OIDP while Cohen’s kappa varied between 0.27 and 0.58 for OHIP-14 items and between 0.23 and 0.65 for OIDP items. Kappa scores for the OHIP-14 and OIDP additive scores were 0.52 and 0.66, respectively. Both measures varied systematically and in the expected direction, with global oral health measures showing criterion validity. The correlation between OIDP and OHIP-14 was rs +0.65. That both measures varied systematically with socio-behavioral factors indicates construct validity.
Both the OIDP and OHIP-14 inventories had reasonable reliability and construct validity in relation to subjective global oral health indicators among adolescents attending high schools in China and thus appear to be useful oral health –related quality of life measures in this context. Overall, the OHIP-14 and OIDP performed equally well, although OHIP-14 had superior content validity due to its sensitivity towards less severe impacts.

Dental caries, dental pain and reported oral problems influence people's oral quality of life and thus their perceived need for dental care. So far there is scant information as to the psychosocial impacts of dental diseases and the perceived treatment need in child populations of sub-Saharan Africa.
Focusing on primary school students in Kilwa, Tanzania, a district deprived of dental services and with low fluoride concentration in drinking water, this study aimed to assess the prevalence of dental pain and oral impacts on daily performances (OIDP), and to describe the distribution of OIDP by socio-demographics, dental caries, dental pain and reported oral problems. The relationship of perceived need estimates with OIDP was also investigated.
A cross-sectional study was conducted in 2008. A total of 1745 students (mean age 13.8 yr, sd = 1.67) completed an extensive personal interview and under-went clinical examination. The impacts on daily performances were assessed using a Kiswahili version of the Child-OIDP instrument and caries experience was recorded using WHO (1997) criteria.
A total of 36.2% (41.3% urban and 31.4% rural, p < 0.001) reported at least one OIDP. The prevalence of dental caries was 17.4%, dental pain 36.4%, oral problems 54.1% and perceived need for dental treatment 46.8% in urban students. Corresponding estimates in rural students were 20.8%, 24.4%, 43.3% and 43.8%. Adjusted OR for reporting oral impacts if having dental pain ranged from 2.5 (95% CI 1.8–3.6) (problem smiling) to 4.7 (95% CI 3.4–6.5) (problem sleeping),- if having oral problems, from 1.9 (95% CI 1.3–2.6) (problem sleeping) to 3.8 (95% CI 2.7–5.2) (problem eating) and if having dental caries from 1.5 (95% CI 1.1–2.0) (problem eating) to 2.2 (95% CI 1.5–2.9) (problem sleeping). Students who perceived need for dental care were less likely to be females (OR = 0.8, 95% CI 0.6–0.9) and more likely to have impacts on eating (OR = 1.9, 95% CI 1.4–2.7) and tooth cleaning (OR = 1.6, 95% CI 1.6–2.5).
Substantial proportions of students suffered from untreated dental caries, oral impacts on daily performances and perceived need for dental care. Dental pain and reported oral problems varied systematically with OIDP across the eight impacts considered. Eating and tooth cleaning problems discriminated between subjects who perceived need for dental treatment and those who did not.
Although oral health care is a vital component of overall health, it remains one of the greatest unattended needs among the disabled. The aim of this study was to assess the oral health status and oral health-related quality of life (Child-OIDP in 11-13-year-old) of the visually challenged school attendants in Khartoum State, the Sudan.
A school-based survey was conducted in Al-Nour institute [boys (66.3%), boarders (35.9%), and children with partial visual impairment (PVI) (44.6%)]. Two calibrated dentists examined the participants (n=79) using DMFT/dmft, Simplified Oral Hygiene Index (OHI-S), dental care index, and traumatic dental injuries (TDI) index. Oral health related quality of life (C-OIDP) was administered to 82 schoolchildren.
Caries experience was 46.8%. Mean DMFT (age≥12, n=33) was 0.4 ± 0.7 (SiC 1.6), mean dmft (age<12, n=46) was 1.9 ±2.8 (SiC 3.4), mean OHIS 1.3 ± 0.9. Care Index was zero. One fifth of the children suffered TDI (19%). Almost one third (29%) of the 11–13 year old children reported an oral impact on their daily performances. A quarter of the schoolchildren (25.3%) required an urgent treatment need. Analysis showed that children with partial visual impairment (PVI) were 6.3 times (adjusted) more likely to be diagnosed with caries compared to children with complete visual impairment (CVI), and children with caries experience were 1.3 times (unadjusted) more likely to report an oral health related impact on quality of life.
Visually impaired schoolchildren are burdened with oral health problems, especially caries. Furthermore, the 11-13 year olds' burden with caries showed a significant impact on their quality of life.

Oral health-related quality of life (OHRQoL) measures are being increasingly used to introduce dimensions excluded by normative measures. Consequently, there is a need for an index which evaluates children's OHRQoL validated for Brazilian population, useful for oral health needs assessments and for the evaluation of oral health programs, services and technologies. The aim of this study was to do a cross-cultural adaptation of the Child Oral Impacts on Daily Performances (Child-OIDP) index, and assess its reliability and validity for application among Brazilian children between the ages of eleven and fourteen.
For cross-cultural adaptation, a translation/back-translation method integrated with expert panel reviews was applied. A total of 342 students from four public schools took part of the study.
Overall, 80.7% of the sample reported at least one oral impact in the last three months. Cronbach's alpha was 0.63, the weighted kappa 0.76, and the intraclass correlation coefficient (ICC) 0.79. The index had a significant association with self-reported health measurements (self-rated oral health, satisfaction with oral health, perceived dental treatment needs, self-rated general health; all p < 0.01).
It was concluded that the Child-OIDP index is a measure of oral health-related quality of life that can be applied to Brazilian children.
The study objective was to compare children’s oral health related quality of life (OHRQoL) in schools with 6 years of implementation of a health promoting school model in Malaysia, i.e. the Doktor Muda Programme (DMP) and in schools without the DMP.
This report was part of a larger study to evaluate the DMP impact on schoolchildren’s oral health knowledge, attitudes, behaviour, caries progression and OHRQoL. It was conducted in Negri Sembilan state. The sample comprised 3455, Year 6 (11–12 year old) children; 1282 from DMP (intervention) and 2173 from non-DMP (control) schools. The Malay Child-OIDP index was used to evaluate children’s levels of oral impacts on 8 daily performances after 6 years of DMP implementation (2006–2011). Prevalence, score, impact intensity, causes and extent of impacts were compared. Chi-square and Mann–Whitney tests were used in the data analysis.
Overall response rate was 95.1%. Prevalence of overall impacts was 57.8% and 60.8% (mean total impact score was 7.10 and 7.77) in the intervention and control group, respectively. The three most frequently affected performances in both groups were eating, cleaning teeth and emotional stability. Significantly less DMP children had oral impact on cleaning teeth (p = 0.034). The majority of children with impacts in both groups reported ‘very little’ to ‘moderate’ levels of impact intensity. Significantly more DMP children reported having ‘very little’ and ‘little’ levels of impact intensity on cleaning teeth (p = 0.037) and emotional stability (p = 0.020), respectively. Significantly less DMP children reported having ‘very severe’ level of impact intensity on speaking (p = 0.038). The most prevalent cause of impacts in both groups was toothache. Significantly less DMP children reported bleeding gums (p = 0.016) and presence of plaque/calculus as causes of impacts (p = 0.032). About 75% of children with impacts in both groups reported having up to four daily performances affected.
This study showed that the health promoting school model, i.e. the Doktor Muda Programme for primary schools in Malaysia had some positive impacts on 11–12 year old children’s oral health related quality of life.

There has been an increase in the development and use of oral health-related quality-of-life (OHRQoL) measures in the past two decades. This study aimed to assess the association between OHRQoL and clinical oral health measures, among mid-level school children in Southeast of Iran.
Materials and Methods:
A cross-sectional study was conducted on a random cluster sample of 11-13 year-old student population. Consented participants interviewed for OHRQoL measurements using Persian version of child-oral impacts on daily performances (OIDP). Oral examination was done by a trained dentist using WHO oral health assessment form, version 2011. Data were analyzed by SPSS software version 20 using Mann–Whitney and correlation tests.
A total of 400 school children participated. The overall mean of decayed missing filled teeth (DMFT) was 1.76 ± 2.4. A total of 82% of the school children presented the impact of oral problems in at least one of the eight daily performances. As DMFT increased, the OIDP score tended to increase or quality-of-life of children tended to be worse (r = 0.397, P < 0.001).
The results showed a positive relation between some oral health status and quality-of-life score.

Promoting oral health of adolescents is important for improvement of oral health globally. This study used baseline-data from LASH-project targeting secondary students to; 1) assess frequency of poor oral hygiene status and oral impacts on daily performances, OIDP, by socio-demographic and behavioural characteristics, 2) examine whether socio-economic and behavioural correlates of oral hygiene status and OIDP differed by gender and 3) examine whether socio-demographic disparity in oral health was explained by oral health-related behaviours.
Cross-sectional study was conducted in 2009 using one-stage cluster sampling design. Total of 2412 students (mean age 15.2 yr) completed self-administered questionnaires, whereas 1077 (mean age 14.9 yr) underwent dental-examination. Bivariate analyses were conducted using cross-tabulations and chi-square statistics. Multiple variable analyses were conducted using stepwise standardized logistic regression (SLR) with odds ratios and 95% Confidence intervals (CI).
44.8% presented with fair to poor OHIS and 48.2% reported any OIDP. Older students, those from low socio-economic status families, had parents who couldn't afford dental care and had low educational-level reported oral impacts, poor oral hygiene, irregular toothbrushing, less dental attendance and fewer intakes of sugar-sweetened drinks more frequently than their counterparts. Stepwise logistic regression revealed that reporting any OIDP was independently associated with; older age-groups, parents do not afford dental care, smoking experience, no dental visits and fewer intakes of sugar-sweetened soft drinks. Behavioural factors accounted partly for association between low family SES and OIDP. Low family SES, no dental attendance and smoking experience were most important in males. Low family SES and fewer intakes of sugar-sweetened soft drinks were the most important correlates in females.
Socio-behavioural factors associated with higher odds ratios for poor OHIS were; older age, belonging to the poorest household category and having parents who did not afford dental care across both genders.
Disparities in oral hygiene status and OIDP existed in relation to age, affording dental care, smoking and intake of sugar sweetened soft drinks. Gender differences should be considered in intervention studies, and modifiable behaviours have some relevance in reducing social disparity in oral health.
