Cross-sectional evaluation of the periapical status and quality of root canal treatment in a selected population of urban Turkish adults.
OBJECTIVE
To investigate the prevalence of apical periodontitis and the quality of root canal treatment in an adult Turkish population who visited a university dental clinic.


CONCLUSIONS
The periapical status of 8863 teeth belonging to 375 patients was evaluated by two pre-calibrated observers from panoramic radiographs. The presence of apical periodontitis, and the prevalence and quality of root fillings were recorded. The relationship between the radiographic quality of root fillings and apical periodontitis was examined by chi-squared statistical-analysis. Of 8863 teeth, 470 (5.3%) had undergone root canal treatment. Forty-seven per cent of all the subjects had at least one root-filled tooth. Periapical radiolucencies were visible on 4.2% of teeth examined, with 53.5% of root-filled teeth presenting apical periodontitis. Ninety-one per cent of root-filled teeth with periapical pathosis were determined to have inadequate root fillings. A statistically significant correlation was found between the quality of root fillings and the presence of apical periodontitis (P < 0.05).


CONCLUSIONS
The radiographic quality of root fillings correlated with periapical radiographic signs of pathosis in a selected population of Turkish adults. There is a need to improve the standards of root canal treatment in the study population.
