Association of Quality of Root Canal Fillings and Coronal Restorations on the Periapical Status of Adult Population in Pokhara Academy of Health Sciences

Abstract

INTRODUCTION A cross-sectional study was done to determine the prevalence of apical periodontitis (AP) in root canal treated teeth in a selected population, and to evaluate the association of the quality of root canal fillings and Coronal restorations (CR) on the Periapical status of root-filled teeth. MATERIAL AND METHODS Total of 270 Orthopantomograms (OPGs) were evaluated. Out of which root canal treatment (RCT) had been performed in 400 teeth. RESULTS Patients with inadequate root canal filling length (77.4%), density (76.1%) and coronal restoration (80.1%) had significantly higher apical periodontitis seen than those with adequate root canal filling length (38.5%), density (48.1%) and coronal restoration (47.4%) (p<0.001, p<0.001, p<0.001 respectively). CONCLUSION Our study revealed that combination of adequate CR, adequate density of root canal filling and adequate length of root filling resulted in significantly reduced incidence of AP.
