Emprego do hidróxido de cálcio e associações na endodontia: uma revisão de literatura.

Abstract

Intracanal medication is an important and widely used tool in endodontic therapy, since it aims to eliminate microorganisms that infect the root canals. Among the various medications used in endodontics it can be highlight calcium hydroxide and their associations. The objective of the present study had as objective to analyze the use of calcium hydroxide and their associations as intracanal medication in endodontic treatment, through a literature review. For an explanation of the topic, we analyzed publications made between the years 1993 and 2016 through the databases: Capes, Pubmed, Lilacs and Scielo. Scientific articles that only presented the abstract were excluded, and the text is not available in full. Calcium hydroxide appears as a white powder and pH about 12.8. It has anti-inflammatory and antimicrobial action, fundamental requirements for endodontic treatment. Because of its presentation in the form of powder, its use in endodontics should be made associated with vehicles that can facilitate their introduction into the root canal, which can be viscous or aqueous. Associations made with camphorated para-chlorochlorophenol (PMCC), zinc oxide and chlorhexidine have the objective of potentializing the effect on microorganisms.It is possible to conclude that calcium hydroxide and their associations are widely used in endodontics providing a more effective treatment in the fight against pathogens that invade the root canal, thus contributing to the success of the endodontic therapy.
