Abstract

The purpose of this study is to evaluate the effect of a bioactive glass-based root canal sealer, Nishika Canal Sealer BG (CS-BG), on the incidence of postoperative pain (PP) after root canal obturation (RCO). Eleven dentists performed pulpectomy or infected root canal treatments for 555 teeth. During RCO, CS-BG was used. After RCO, the rate of PP and the factors affecting PP (pain during RCO and pain immediately after RCO) were analyzed. PP was observed in eight teeth (1.5%), and within 7 days after RCO, there were no teeth with pain. In these teeth with PP, there was a significant difference in the occurrence of pain during RCO, but not in the occurrence of pain immediately after RCO, when compared with pulpectomy and infected root canal treatment. These clinical results show that CS-BG has an excellent biocompatibility, and can suppress the distress of patients during RCO.

Highlights

Published systematic reviews reported that postoperative pain (PP) in endodontics ranges between 1.5 and 58%, as described in different studies [1,2,3]
The attribution of the incidence of pain to any specific factor is difficult in clinical research, because endodontic treatment comprises a complex number of procedures, including chemo-mechanical debridement and root canal obturation
Root canal obturation is usually completed in the same appointment, as it has been affirmed that the root canal is the most clean with the least microbial load immediately after chemo-mechanical preparation [20]

Summary

Introduction

Published systematic reviews reported that postoperative pain (PP) in endodontics ranges between 1.5 and 58%, as described in different studies [1,2,3]. The presence of PP is associated with a number of endodontic treatment-related parameters, including the estimation of working length with an apex locator connected to every file [4], number of visits [5], choice of instrumentation [6], and choice of root canal sealer [7]. PP associated with root canal sealer ranges between 5 and 20% [8,9,10]. Root canal sealers with high biocompatibility and high sealing properties are desired.
