Cimentos biocerâmicos em endodontia : revisão de literatura.

Abstract

It is unquestionable that root canal filling plays a big role in endodontic therapy, which when done with a minimum amount of errors, can guarantee the success of the treatment.The material used to replace the nervous tissue inside the root canal, called gutta-percha, needs to be allied to a sealing cement, which already exist in several compositions, brands and properties in the current market. In this scenario, there is a material that is biocompatible with dental structure and that presents a promising future in dentistry and especially in endodontics: Bioceramic Cement. The main objective of this literature review is to research scientific data to show dentists and academics the necessary basis to help in the best choice of shutter cement as well as to observe the pros and cons of the use of bioceramic cements and to define if there is a benefit in its use in the obturation of root canals. The present work emphasizes recently published articles on the subject and also compares with the results of older studies. MTA is a bioceramic material widely used mainly in endodontic surgeries in cases of teeth with perforations, calcifications, complicated root anatomy or dental pathologies and from excellent results, new calcium silicate based materials have been developed with characteristics that allow its use as obturator cements. Results such as moderate toxicity, adequate radiopacity, good antimicrobial activity due to its alkaline ph, prey reaction even in the presence of humidity in the channel and drainage with results superior to those recommended were found during the study. It is concluded then, from the bibliographical review of this work that bioceramic cements present good properties and satisfactory results for their use in endodontics.
