Prevalence of periapical lesions associated with endodontically treated teeth of an adult Syrian subpopulation, and its relation to the quality of root canal fillings

الملخص EN

Background and Objective: Purpose of this study was to determine the prevalence of apical periodontitis in endodontically-- treated teeth in adult Syrian patients and to evaluate the influence of root canal fillings quality on the periapical status of these teeth.

Methods and Materials: Periapical status and root canal fillings quality of 784 endodontically -treated teeth of Syrian adult patients who attended Damascus dental school were evaluated using panoramic radiographs.

Chi-square test was used for statistical analysis.

Results: Overall, the prevalence of apical periodontitis (AP) in endodontically treated teeth was 33.4%.

Only 18.5 % of teeth had endodontic treatments rated as adequate.

Number of teeth with healthy periapex for cases with adequate endodontic treatment was 95.2%, which was significantly high when compared to teeth with inadequate treatment (66.6%).

The highest percentage of inadequate root filling was found in the molar teeth and Mandibular incisors.

Conclusion: Our results indicate high prevalence of AP in Syrian subpopulation associated with inadequate root canal filling.
