Evaluation of Demands and Needs For Dental Care in a Sample of the Turkish Population

Abstract

Objectives:

To evaluate the demands and needs for dental care and to identify the level of dental and periodontal status in patients of different age groups visiting the Faculty of Dentistry, Marmara University, Istanbul, Turkey.

Methods:

A total of 1000 first-visit patients (517 female and 483 male) were examined and questioned. The main complaint of each patient was recorded and considered to be a measure of demand for dental care. The World Health Organization’s (WHO) basic methods were used to determine the tooth-based and orthodontic normative treatment needs. Periodontal status was determined by using the Community Periodontal Index of Treatment Needs (CPITN). In addition, prosthetic normative needs were assessed.

Results:

This study showed that patients in different age groups required different treatments and had different main complaints. In total, 89.3, 74.1 and 57.7% of the patients named periodontal, restorative and prosthetic care as their main complaint, respectively. Approximately 21% of the total did not need restorations and extractions, and only 12% of the sample did not have a normative periodontal treatment need. About half of subjects needed fixed partial dentures.

Conclusions:

Normative treatment needs of patients were very high. Therefore, a new national strategy for oral health must be devised for Turkey. This study can assist in setting the baseline for that strategy.

INTRODUCTION

In recent years, rapid changes have occured in the patterns of oral diseases across countries. In developing countries, oral disease data are primarily collected to aid authorities planning health care systems. These epidemiological data may allow for an improved understanding of the nature of oral diseases and changing disease patterns at the population level because these studies are conducted in populations that so far have had very limited access to formal oral health care.19

Studies concerning oral health care of the population are scarce in Turkey. There are only a few reports providing information about dental care treatment needs.1013 In contrast, there are no reports about the treatment demands for dental care.

There are various definitions of need.14 The definition that is most often quoted is the taxonomy proposed by Bradshaw15 that identifies four categories of need:

  1. Normative need, defined by the professional.
  2. Felt need, which is equated with want.
  3. Expressed need or demand; felt need is converted into action by seeking care.
  4. Comparative need, which is assessed by comparing care received by different people with similar characteristics.

The concept of need is central to the planning, provision and evaluation of health services. For effective planning and evaluation of any health service, both estimates of levels of need as well as demand for treatment should be taken into account.14

The aim of the present study was to determine the demands and needs for dental care and to identify the level of dental and periodontal status of patients from different age groups who visited Marmara University, Faculty of Dentistry, Istanbul, Turkey.

MATERIALS AND METHODS

The study group consisted of 1000 patients, 16–65 years old, who sought treatment for the first time at Faculty of Dentistry of Marmara University during a period of 12 months from 2004 to 2005. All patients were examined in the Department of Oral Diagnosis and Radiology. Personal data of the patients and their main complaint or main reason for visiting were recorded. An initial examination was conducted to determine the treatment necessary to address the main complaint. This was followed by an assessment of normative treatment needs of each patient.

The WHO’s basic methods were used to determine the tooth status and the tooth-based treatment needs,16 and the Community Periodontal Index for Treatment Need (CPITN)10,17 was used to record each patient’s scores. The CPITN scores are: 0 = healthy, 1 = bleeding on gentle probing, 2 = calculus, 3 = shallow pocketing of 4 or 5 mm, and 4 = deep pockets of 6mm or more. The clinical examination of the patients was carried out using a dental mirror, an explorer and the periodontal probe recommended by WHO.

Criteria for the assessment of incomplete dentition were based on the concept of the shortened dental arch proposed by Kayser and Witter.18 They suggested that a minimum of 20 teeth is sufficient to meet oral functional demands, and therapy should be aimed at preserving or replacing teeth in the premolar and anterior regions. If there are less or will be less than 20 teeth after the indicated extractions, they deemed a person to be in need of a partial denture (presence of tooth spaces anterior to the second premolars). A full denture was indicated when an arch was edentulous or had only one or two remaining teeth. Orthodontic treatment was indicated in the presence of crowding or spacing of more than 4 mm, anterior cross-bite, openbite and maxillary overjet estimated to be 9 mm or more.14

Four dentists participated in the survey and calibration trials were performed initially to ensure an inter-examiner consistency of at least 85% in recording. For calibration, 20 patients were evaluated and not included in the main study. Inter-examiner agreement was measured by Cohen’s Kappa statistic.

Statistical analyses were performed using the Statistical Package for Social Sciences (SPSS Inc., Chicago, IL, USA) 10.0 programme for Windows. Descriptive statistical methods (mean, standard deviation) were used for the evaluation of the data. The quantitative data was compared using the chi-squared test, and the value of P<.05 was considered significant.

RESULTS

The sample surveyed consisted of 517 females (51.7%) and 483 males (48.3%). Table 1 shows the distribution of subjects who required treatment according to their age groups and gender. A higher percentage of females than males sought treatment except in the 16 and > 65 age groups.

Distribution of subjects according to age group and gender.

The percentage distribution of the main complaint in subjects in relation to age groups is shown in Table 2. When the age groups were considered separately, malocclusion was the the most common complaint in the 16 age group (90.5%) and a similar trend in treatment demand was observed in the 17–34 age group (54.4%). Tooth decay was the main complaint in the 17–34 and 35–44 age groups. The 35–44 and 45–64 age groups mainly required fixed partial dentures and complained of bleeding gums, whereas removable dentures was the most common demand in the >65 age group. Painful gums was the most common complaint in the 35–44 age group. Statistically significant differences were found for fixed and removable dentures, malocclusion, bleeding gums and painful gums, respectively, according to age (P<.01 and P=0.002).

Table 3 shows the type of care required for the main complaint of subjects according to age group. People in the 16 and 17–34 age groups needed orthodontic care (94.8 and 57.8%, respectively). Restorative care was the most prevalent need in the 17–34 (77.7%) and 35–44 (76.1%) age groups, and those in the 45–64 age group needed periodontal, prosthetic and surgical care (95.8, 90.9 and 13.3%, respectively). The majority of the >65 (96.0%) and 45–64 (90.9%) age groups needed prosthetic care. All age groups needed periodontal care. In all age groups, 89.3%, 74.1% and 57.7% needed periodontal, restorative and prosthetic care, respectively. There was a statistically significant difference between the type of care required for the main complaint of subject and age groups (P<.0001, P<.001 and P<.01).

Table 4 shows the tooth-based normative treatment needs of subjects according to age group. Older patients needed more extractions and restorations compared to young patients. Restorative and endodontic treatments were more necessary for those in the 17–34 age group than the others (59.3 and 5.8%, respectively). Similarly, people in the 35–44 age group needed more extractions due to caries and periodontal problems than those in the other groups (35.9 and 4.3%, respectively). None of the patients in the >65 age group needed extraction because of periodontal, endodontic and other reasons.

Table 4.
Percentage distribution of tooth-based normative treatment needs in subjects according to age group.

Upper and/or lower full denture treatments were needed by members of the 45–64 and >65 age groups. A higher percentage of subjects in the >65 age group (44.0%) needed partial dentures compared to those in other age groups. Orthodontic treatment was needed by 90.2% of the subjects in the 16 age group, and 76.9% of the 35–44 age group needed fixed dentures (Table 5).

Table 5.
Percentage distribution of normative prosthetic and orthodontic needs in subjects according to age group.

A larger percentage of subjects in the 17–34 age group had a CPITN score of 1. However, those in the 45–64 and 35–44 age groups were more likely to have scores of 3 and 4. A statistically significant difference was observed among CPITN scores and age groups (P<.01 and P<.0001) (Table 6).

Table 6.
Percentage distribution of CPITN scores in subjects according to age group.

In particular, the percentages of subjects in the 35–44 age group with periodontal scores of 1, 2, 3 and 4 were higher than those of other age groups (38.8%, 40.1%, 45.4% and 46.4%, respectively). Periodontal treatment needs, as assessed using CPITN, indicated that 67.6%, 17.6% and 2.8% of the total population needed oral hygiene instruction, scaling and periodontal surgery, and only 12% had no treatment need. Statistically significant differences were observed for normative periodontal treatment needs according to age (P<.0001) (Table 7).

DISCUSSION

Patients’ perception of need frequently gives rise to a demand for health care. Patients are often unaware of the treatment options available and depend on the health care provider to suggest the appropriate care for their conditions.

This study, which is the first to evaluate the general situation regarding the demands for dental care of patients visiting Marmara University, Faculty of Dentistry in Istanbul, Turkey, showed that patients in different age groups requested different treatments and reported different main complaints. For example, in the 16 age group, malocclusion was the most common complaint, and patients in that group requested orthodontic treatment. In addition, the majority of patients demanded treatment for fixed dentures, malocclusion, bleeding gums and decayed teeth, respectively. In previous studies, Ekanayake et al14 revealed that the majority of patients demanded treatment for decayed teeth in Sri Lanka. Similar studies reported that toothache and pain due to dental caries and periodontal diseases were the most common causes of requested treatments.1921

It is the obligation of a dentist not only to provide care for the presenting complaint of patients but also to make them aware of and provide treatment for any other condition that is diagnosed during a routine dental examination. This is necessary as it has been shown that patients are unable to assess their dental treatment needs accurately. Assessment of normative needs in patients who seek dental care at an institution is therefore important as such data could be used to estimate the resources and manpower required to meet the needs of patients.14,22

A less complex and internationally established method of estimating levels of periodontal conditions in populations is the widely used WHO CPITN, which has become an established index and has generated considerable data to identify levels of periodontal conditions of populations for which specific interventions might be considered.10,13 Therefore, we used this method to determine periodontal conditions of patients.

Of the 1000 patients examined, 12% were periodontally healthy (CPITN score 0). However, 67.5% had gingival bleeding (CPITN score 1) and 85.2% had calculus (CPITN score 2). These findings implied that it is important that all age groups, except the >65 group, be assessed to find out their periodontal health status. Consistent with CPITN data reported, the present survey demonstrated high levels of gingival bleeding and dental calculus.5,1012

This study revealed that the predominant need was for periodontal care (88%), followed by restorative (61.1%) and prosthetic care (fixed dentures, 49.1%), respectively. Normative treatment needs detected were similar to the demand for periodontal treatment. However, requests for restorative and prosthetic treatments were found to be much higher than those for normative treatment. These results showed that patients’ awareness about oral health is very good. Only 6.7% of all patients demanded surgical treatment. Unfortunately, the percentage distribution of surgical normative treatment needs in patients was very high. Correct information and knowledge about oral health is necessary to enable individuals to make appropriate decisions regarding necessary dental treatment.23

The patients from different age groups needed different treatments. Normative prosthetic needs were especially high for those in older age groups. On the other hand, the need for normative orthodontic care was higher for younger patients (16 and 17–34 age groups). These treatments are more expensive in private clinics than in a dentistry faculty in Turkey. Therefore, our dentistry faculty can expect a high demand for oral health care.

CONCLUSIONS

The present study included the following findings:

  • Patients’ expressed treatment needs (or main complaints) and normative treatment needs varied in relation to age groups. The majority of patients demanded treatment for fixed dentures, malocclusion, bleeding gums and decayed teeth. Normative prosthetic needs were higher for the older participants, and orthodontic needs were higher for those in the younger age groups.
  • High levels of gingival bleeding and dental calculus were demonstrated, and only 12% of the sample was found to be periodontally healthy with no periodontal treatment needs.
  • Periodontal treatment demand and normative periodontal treatment needs were revealed to be similar. In contrast, restorative and prosthetic treatment demands were found to be higher and surgical treatment demands to be lower compared to normative needs.
