SUMMARY Aim:To determine the distribution and frequency of endodontic treatment and endodontic treatment requirement in permanent teeth. Materials and Methods: Of the 19800 teeth from 775 individuals (age range 16-80 years) were included in the study. All patients were examined clinically and radiologically to determine the teeth requiring endodontic treatment and endodontically treated teeth. For each case, information was collected in a questionnaire including age, gender, education, residence place, income level, frequency of tooth brushing and dental visit. Obtained data were statistically analyzed by using chi-square test with a significance level at p<0,05. Results: Out of 19800 teeth, the frequency of teeth requiring endodontic treatment and endodontically treated teeth was 3% and 4%, respectively. Presence of endodontic treatment showed statistical difference between age subgroups (p<0.05). Gender, frequency of tooth brushing and dental visit had effect on the endodontic treatment requirement (p<0.05).
Conclusion:This study provides an epidemiological data about endodontic treatment in a Turkish population. Such datas will help to identify public dental health problems which will constitute an essential step in improving the general health status of the citizens of this country.
