Investigation of the frequency and distribution of teeth requiring endodontic treatment and endodontically treated teeth

Abstract

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.

Frequency of different indications for endodontic treatment among patients from Pancevo, Serbia

“…Results of this study showed that need for endodontic treatment significantly increases with age. This finding is in agreement with other studies (3,8,10,11) and can be related to increased exposure to caries, periodontal problems and restorative procedures leading to root canal treatment and age-related changes of dental pulp complex. In contrast, Umanah et al found that the highest frequency of endodontic treatment was among patients between 20 and 29 years of age (12).…”

“…In the present study, root canal treatment was more frequently indicated on maxillary teeth. This result is in agreement with the results of numerous studies (2,8,12,15). Oglah et al assumed that this could also be related to the aesthetic reason, as the upper teeth appear more prominent than the lower teeth during smile, making the patient more interested to preserve the upper teeth (1).…”

“…In contrast, Umanah et al found that the highest frequency of endodontic treatment was among patients between 20 and 29 years of age (12). While some authors found that males required endodontic treatment more often than females (8,13,14) and others revealed opposite results (1,2,12), in the present study no significant difference was recorded between genders, beside slightly higher percentage of teeth indicated for endodontic treatment among male subjects.…”

“…While there can be found certain number of studies which evaluate the frequency of endodontically treated teeth, there is not adequate study reporting the endodontic treatment need in the literature. The percentage of teeth indicated for endodontic treatment from the examined sample of this study is higher than in the Tasoker et al and Weiger et al studies, who reported 3% out of 19800 teeth and 2.3% out of 7897 examined teeth (8,9). It should be mentioned that present study included only patients referred to the Department for Endodontics who had at least one tooth indicated for endodontic treatment.…”

“…Frontal teeth (incisors and canines) were the most commonly tooth group indicated for endodontic treatment, followed by premolars and molars. This result can be considered as surprising, bearing in mind that most of the authors state that molars and premolars are the most frequent treated teeth (1,2,8,10,13). The reason for such a result could lie down in the assumption that the frontal teeth are more visible and aesthetic reasons are making the patient more motivated to visit their dentist.…”
