necessary 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. Table 1. 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�C34 age group (54.4%). Tooth decay was the main complaint in the 17�C34 and 35�C44 age groups. The 35�C44 and 45�C64 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�C44 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 2. Percentage distribution of the main complaint in subjects according to age group. Table 3 shows the type of care required for the main complaint of subjects according to age group. People in the 16 and 17�C34 age groups needed orthodontic care (94.8 and 57.8%, respectively). Restorative care was the most prevalent need in the 17�C34 (77.7%) and 35�C44 (76.1%) age groups, and those in the 45�C64 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�C64 (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, Dacomitinib P<.001 and P<.01). Table 3. Percentage distribution of type of care required for the main complaint of subjects according to age group. 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�C34 age group than the others (59.3 and 5.8%, respectively).
