Efectividad del Hidróxido de Calcio con diferentes vehículos en Periodontitis apical

Abstract

Objective. To determine based on the literature review the effectiveness, antimicrobial action at time and pH of calcium hydroxide with different vehicles for intra-duct medication. Materials and methods. For this purpose, a review of articles published in the following databases was carried out: Medline, Scielo, Pubmed, Cochrane Library and Google Scholar, applying a temporal delimitation of 13 years and including any language, in which 30 articles were primarily selected, 10 of which were excluded because they did not meet the inclusion criteria, thus remaining 20. The vehicles that showed better results maintaining a more alkaline pH of calcium hydroxide were propylene glycol, distilled water and 2% chlorhexidine. The vehicle that shows better properties to potentiate the antimicrobial effect that calcium hydroxide possesses, is propylene glycol, a viscous vehicle that presents very good properties to be able to exert a great antimicrobial action combined to calcium hydroxide. Conclusions: Propylene glycol is the preferred one to be used, maintaining a stable and alkaline pH, with a great antimicrobial action thus helping in an effective disinfection of the root canal system.
