1.  Oral health status and treatment needs of children and young adults attending a day centre for individuals with special health care needs 
BMC Oral Health  2008;8:30.
Background
The oral health condition of individuals with special health care needs have been reported in literature to be influenced by various sociodemographic factors, including living conditions and severity of impairment. This study was carried out to determine the oral health status and treatment needs of children and young adults attending a day institution for those with special needs.
Methods
This study was carried out as part of an oral health screening program organized by the institution and consent was obtained from parents and guardians before the screening. All information was supplied by the parents during the screening using a questionnaire completed by the dentist. Oral examination was carried out on all consenting subjects in attendance on the days of screening in the school clinic with parents and teachers in attendance, using standard World Health Organisation oral health indices to assess dental caries, oral hygiene status, malocclusion and other oral health parameters.
Results
Fifty-four subjects aged 3–26 years (mean 12.28 ± 6.82 years) and comprising 72.2% males and 27.8% females participated in the study. Over 90% were from parents of high and middle level educational background. Thirty-six (66.7%) were caries free, with a mean dmft score of 0.7 ± 1.77 and mean DMFT score of 0.4 ± 1.44 with no significant difference across gender (p = 0.5) and parents' educational status (p = 0.43). The mean OHI-S of the total population in this study was 1.36 ± 0.16. Females had a mean score of 0.88 ± 1.10 while males had a mean score of 1.55 ± 1.24 with no significant difference (p = 0.6). Twenty-five (46.3%) had good oral hygiene, 17 (31.5%) had fair oral hygiene and 12 (22.2%) had poor oral hygiene, with no significant difference across gender (p = 1.11) and age groups (p = 0.07). Fifteen (27.8%) had gingivitis with no significant difference across age groups (p = 0.17). Forty-five (83.3%) had Angle's class I malocclusion, 6(11.1%) class II and 3 (5.6%) class III. Chronologic enamel hypoplasia was found in 9 (16.7%) of the total population. Up to 53.7% of the total population will require oral prophylaxis, 33.3% required restorations on their posterior teeth and 12.9% required veneers for labial facing of hypoplastic enamel.
Conclusion
The subjects in this study had a high prevalence of dental caries and need for restorative care. They would benefit from parental education on diet modification, improvement of oral hygiene practices and regular dental visits.

2.  Knowledge and behavior of Nigerian dentists concerning the treatment of children with special needs 
BMC Oral Health  2006;6:9.
Background
Children with special needs (CSN) are reported to receive less adequate dental care due to various behavioral problems and barriers created by dental professionals. This study was carried out to determine the knowledge and behaviour of Nigerian dentists concerning the treatment of CSN.
Methods
Questionnaires consisting of open and closed ended questions requesting socio-demographic information, type of practice, undergraduate and postgraduate training, self-rated knowledge and behaviour concerning care of CSN, were hand delivered to 359 dentists in the 3 geographical zones of Nigeria over a period of 8 weeks. Responses were compared across age groups, gender, type of practice and training received.
Result
Two hundred and eighty questionnaires were returned completed, constituting 79.9% response rate. Most of the respondents were aged 30 – 39 years (44.3%). There were more males (56.1%) and more recent graduates of 10 years and below (78.5%). Over 80% of respondents had treated children with disabilities, those with physical disabilities being most encountered. Only 19.3% of respondents rated their knowledge of management of CSN as adequate, with no significant difference across age groups and gender, but with a significantly higher number of older graduates reporting to have adequate knowledge (p < 0.05). Those who had undergraduate training in care of CSN were 69.5% compared with only 12.8% who had post graduate training. Only 11.8% rated their undergraduate training as adequate. Thirty seven percent of respondents rated the CSN they had treated as very challenging. A higher proportion of older graduates (of more than 10 years post graduation) and those who rated their undergraduate training as inadequate used sedation and general anaesthesia. Seventy one percent of respondents were willing to treat CSN, with no significant difference across age groups, gender and training, but with a significantly higher percentage among those who had rated their knowledge as adequate. Most of those who were unwilling to treat CSN felt their management was tedious and challenging.
Conclusion
From this study, very few dentists reported to have adequate knowledge of management of CSN, irrespective of age, gender and place of practice. A significant number of those with more experience rated their knowledge as adequate. Although most dentists rated the children's behaviour as challenging, they indicated their willingness to treat them in their practices.

3.  Mandibular facial talon cusp: Case report 
BMC Oral Health  2005;5:9.
Background
Talon cusp is a supernumerary structure projecting from the dento-enamel junction to a variable distance towards the incisal edge of an anterior tooth. Studies have shown that it consists of enamel, dentine and a variable amount of pulp tissue. Hyperactivity of the enamel organ during morphodifferentiation has been attributed to its formation. Most previous reports have been made concerning the occurrence of this structure on primary and permanent teeth and mostly on the palatal aspect. Only few have been reported on the facial aspect of the teeth. When it occurs, the effects are mainly aesthetic and functional and so early detection and treatment is essential in its management to avoid complications.
Case presentation
An unusual case of talon cusp on the facial aspect of a mandibular central incisor is reported. Its presence resulted in attrition of the opposing tooth. Reduction of the cusp and topical application of fluoride gel was initiated.
Conclusion
The management and treatment outcome of talon cusp depends on the size, presenting complications and patient cooperation.
