The purpose of this study was to compare the quality of coronary restorations and root canal fillings with the periapical status of root-filled teeth, in a subpopulation of Turkish individuals.
Materials and method: The study included 18,210 randomly selected, 20- to 70-year-old patients referred to the Dental Faculty of Ondokuz Mayis University. A total number of 1,027 root-filled teeth from 780 patients (645 females, 382 males) matched these criteria. Additionally, the radiographs were separated according to the age and gender of patients. Panoramic radiographies compared the quality of coronary restorations and root canal fillings with the periapical status of root-filled teeth.
Results: The most numerous root-filled teeth were observed in the 20- to 29-year-old group, in both genders. For the maxillary and mandibular incisive teeth, the prevalence of inadequate coronary restoration with apical periodontitis (AP) is 29.04% in males and 70.96%, respectively, in females (p<0.05). For the posterior teeth, in both jaws, the prevalence of inadequate coronary restoration with AP is 38.99% in males and 61.02%, respectively, in females. The AP prevalence in inadequate coronary restorations was significantly higher for the posterior than for the anterior teeth. Conclusions:This study concludes that adequate coronary restorations and crowned root-filled teeth significantly reduce AP incidence.
