Abstract

Due to the limitations of sodium hypochlorite (NaOCl), such as its high chemical instability and damage to dentin components, new irrigating solutions are constantly being investigated. In this sense, calcium hypochlorite [Ca(OCl)2] stands out as promising. Therefore, this study aimed to compare the antibacterial effect of Ca(OCl)2 with NaOCl against Enterococcus faecalis. The protocol for this study is available online (https://osf.io/zbexy/). Studies without time and language restrictions that compared Ca(OCl)2 with NaOCl in the fight against E. faecalis were selected. The search and study screening were performed in Embase, PubMed, Scopus, and Web of Science databases by 2 independent researchers. The initial search yielded 689 citations, of which 11 were included. The use of NaOCl and Ca(OCl)2 solutions occurred at concentrations of 0.5%, 1%, 2.5%, 5%, 5.25%, and 6%, using different instrumentation techniques (manual, rotary or reciprocating instruments), irrigation techniques (conventional or ultrasonic) and auxiliary methods for decontamination (Photodynamic Therapy – PDT). The studies corroborate that Ca(OCl)2 has an effective antibacterial effect against E. faecalis, regardless of its concentration, instrumentation and irrigation techniques, and use of auxiliary methods for decontamination, with comparable results to NaOCl.
