SUCCESS FREQUENCY OF ROOT CANAL FILLING MATERIALS MOST USED IN PEDIATRIC DENTISTRY

Abstract

Introduction: There is no consensus on the literature about the best root canal filling material for primary teeth. Objective: The aim of this study was to describe the root canal filling materials most widely used in clinical pediatric dentistry, showing the observed success rates. Sources of data: A search, limited to the last
10 years and, no language restriction, was performed in October 2018 in the PubMed, Cochrane and LILACS databases using the terms “pulpectomy” and “primary teeth”. This narrative literature review included clinical and randomized controlled trials conducted on children who had undergone pulpectomy as root
canal therapy, with at least six months of clinical and radiographic follow-up. Synthesis of data: A total of 254 papers were retrieved from the databases. After applying the inclusion and exclusion criteria, 25 papers were included in this review. Zinc oxide and eugenol (ZOE) based paste was still the most widely used root canal filling material for primary teeth in pediatric clinical research, showing an overall clinical and radiographic success ranging from 63.3% to 93.3%. Conclusion: ZOE based paste is still the most used material for root canal filling in primary teeth, although there is a trend in the use of iodoform with calcium hydroxide pastes, which show high frequencies of success.
