AVALIAÇÃO DO ESCOA MENTO E EXTRAVASAMENTO DE CINCO CIMENTOS ENDODÔNTICOS ATRAVÉS DE RADIOGRAFIA DIGITAL : UM ESTUDO IN VITRO.

Introduction: In Endodontics, the search for long-term clinical success depends on the knowledge of properties of several dental materials. Aim: To evaluate the flow and extravasation of endodontic sealers inside of channels made with resin blocks (IM Brazil LTDA). Five endodontic sealers were tested (AH Plus, Pulp Canal Sealer, Endomethasone, Sealer 26 and Endofill). Material and Methods: For the in vitro study, we used 20 transparent blocks of simulated channels, where each block had 3 channels: cervical, middle and apical. The Edomethasone sealer presented a smaller percentage of flow (66.67%) compared to the others. With regard to extravasation, cervical channels of Endomethasone (50%) and Endofill (50%) groups showed the highest percentage of extravasation. Conclusions: All tested endodontic sealers had good flow and extravasation. The Pulp Canal Sealer was the one that had the highest percentage of average flow. The sealer Endomethasone presented the lowest percentage of flow and AH Plus the lowest average flow in millimeters when evaluated apical channels. [ABSTRACT FROM AUTHOR]
