Aims To examine the efect of the quality of root canal fllings and prosthetic restorations on the frequency of apical periodontitis (AP). Methodology A total of 200 radiographs of 1,098 teeth with indirect restorations were selected. Each case was documented by age, sex, tooth location, tooth type, restoration type and presence of root canal treatment (RCT). Teeth were categorised as healthy or diseased considering periapical health. The quality of RCT and prosthetic restorations was categorised by radiographic and clinical examinations. Data were analysed using chi-squared test and logistic regression. Results Inadequate prosthetic restorations were found to be less healthy than the adequate ones. Statistical signifcance was found in teeth with RCT, which had a higher rate of AP (15.8%). Root-flled teeth categorised as inadequately treated (24.1%) were signifcantly unhealthier than the adequately root-flled teeth. Teeth with inadequate prosthetic restorations and RCT had an increase in AP risk of 6.41 and 20.74 times, respectively (p <0.05). Conclusions Results showed that AP risk was increased by both inadequate RCT and prosthetic restorations. Quality of RCT signifcantly afected periapical health more than the quality of prosthetic restorations. Not only radiographic but also clinical examination of restorations is required for successful evaluation.
