ABSTRACT

One of the aims of endodontics is to eliminate microorganisms and prevent reinfection in the root-canal system. To achieve this, one of the procedures performed in endodontic therapy is the sealing of the root canals. This implies filling the root canal with as hermetic an inert material as possible and a sealer that encourages the process of apical and periapical repair. Microorganisms can remain in the root-canal system even after biomechanical preparation and irrigation, as they may have a complex anatomy. In endodontics, one of the desired properties of an endodontic sealer is antimicrobial activity to eliminate resistant bacteria. Calcium hydroxide-based sealers are used due to their antimicrobial activity and role in endotoxin degradation, among other properties. These were the premises that gave rise to this study, which aimed to evaluate the antimicrobial activity and biocompatibility exhibited by a calcium hydroxide-based endodontic sealer based on a review of the literature. As a result of this review, we were able to conclude that while calcium hydroxide-based sealers do display biocompatibility and antimicrobial activity, their biological properties can vary depending on the method used and the time of application.
