Influence of Root Canal Irrigants on Fracture Resistance of Teeth: A Narrative Review

Abstract

Various single and combined irrigation solutions and protocols are used during endodontic treatment. There is no review available on the effect of root canal irrigation solutions on root and crown fracture resistance. This review evaluates the effect of root canal irrigation solutions on bonding and root and crown fracture. The MEDLINE-PubMed and SCOPUS databases were searched for appropriate papers addressing the effects of irrigation solutions on crown and root fracture resistance and bond strength. Databases were searched from 2005 to 2014. The search was performed using a variety of keywords, including root fracture resistance, crown fracture resistance, resistance, bonding, and canal irrigants. Using multiple key words and different strategies, 119 publications were initially screened. The abstracts of these 119 publications were scanned for relevance, and 45 full-text articles were selected. Based on the review of all the relevant papers, it can be concluded that root canal irrigation solutions can affect the fracture resistance of the crown and root.
