Introduction: The combination of mechanical instrumentation of the root canal system, chemical debridement, and filling with an inert material, known as root canal treatment (RCT), is used to preserve or restore the health of the periradicular tissues. Even within authorized protocols, the manner in which therapeutic procedures are carried out is so varied that it is difficult to characterize it more accurately. The aim of the present study is to correlate the pulpal and periapical status to the frequency of sealer extrusion in teeth undergoing root canal treatment. Materials and methods: The present study was conducted in the Department of Conservative Dentistry & Endodontics. We assessed the patient’s records and analysed data of 8,000 patients. Patients who have undergone RCT were initially screened. Among these the patients with sealer extrusion cases were filtered based on obtained radiographs. The data is tabulated using excel and analysed with SPSS. Results: In the present study, the canal with 6% taper showed to have higher incidence of sealer extrusion (p<0.05). The canal taper of 6% (91.6%) showed to have more sealer extrusion and in terms of teeth, lower posterior teeth (38%) tend to show the higher incidence of sealer extrusion. Master cone size of 30 (48%) showed to have high frequency of sealer extrusion when compared to remaining master cone sizes. In regard to pulpal and periapical status, patients who presented with chronic asymptomatic pulpitis (89%) and chronic periapical periodontitis (78%) showed the most common sealer extrusion. Conclusion: This study revealed that sealer extrusion is mostly based on the degree of taper and apical diameter enlargement. Sealer extrusion also seemed to have an influence on pulpal and periapical status.
