| Abstract | Introducao: todas as fases do tratamento endodontico sao muito importantes e interdependentes. A obturacao do canal radicular, apos o preparo biomecânico, e a etapa fundamental e determinante no sucesso do tratamento endodontico convencional. A adesao do cimento obturador tanto a guta-percha quanto a dentina e desejavel para o estabelecimento de melhor selamento apical, apos a obturacao endodontica Objetivo: o objetivo do presente trabalho foi comparara radiopacidade de tres cimentos endodonticos: Endofill, FillApex associado a 20 por cento de hidroxido de calcio e Sealer 26. Metodologia: o ensaio de radiopacidade seguiu a norma ISSO 6876:2001, onde foram confeccionados corpos de prova cilindricos com os cimentos em teste e cilindros de dentina de contendo a mesma espessura. Todos os cimentos foram devidamente proporcionados e espatulados conforme orientacao do fabricante e inseridos em aneis metalicos com 10 mm de diâmetro e 1 mm de altura, conservados a temperatura de 37oC. Apos presa dos cimentos, as placas foram retiradas e as espessuras dos corpos de prova conferidas com paquimetro manual. Os corpos de prova, os cilindros de dentina e o penetrometro foram dispostos sobre filme oclusal insight Kodak E, onde foram sensibilizados com um aparelho de raios-X. Apos o processamento das peliculas, as imagens foram digitalizadas e analisadas quanto a densidade radiografica no programa Digora 1.51. Resultados: os resultados mostraram que o Sealer 26 apresentou os maiores valores de radiopacidade, seguido do EndoFill, e o que apresentou menor densidade de radiopacidade foi o FillApex (P Introduction: all stages of the endodontic treatment are very important and interdependent. The root canal filling after biomechanical preparation is a fundamental and crucial step to the success of conventional endodontic treatment. The adhesion of the sealer both the gutta-percha as the dentin is desirable to establish better apical seal after endodontic treatment. Objective: the aim of this study was to evaluate the radiopacity of three endodontic sealers: Endofill, FillApex associated on 20 pe cent calcium hidoxydeand Sealer 26. Methods: The test of radiopacity followed the ISO 2001: 6876, where specimens were made with cylindrical test and cements in dentin of cylinders containing the same thickness. All the endodontic sealers were manipulated according to manufacturer's instruction. Cylindrical samples were fabricated from each material by pouring the manipulated cements into metallic rings measuring 10 mm in diameter by 1 mm thick according ISO 6876 specifications. The filled rings were kept at 37°C until cements were completely set. The specimens were then removed, and the thickness was checked with a manual caliper. All the cement and dentin specimens were placed on occlusal films along an aluminum step-wedge graduated from 2 to 16 mm Al. Radiographs were taken using a radiographic unit. After processing of the film, the images have been scanned and analyzed on the radiographic density in Digora 1.51. Results: the results showed that the Sealer 26 presented the highest values of radiopacity, followed by the EndoFill, and that showed lower radiopacity than FillApex. Conclusion: all cements analyzed have reported values above those recommended by ISO standards and dentin, being the Sealer 26 what got better performance in this study. (AU) |
