Evaluación in vitro de la microfiltración apical empleando dos cementos selladores a base de hidróxido de calcio (sealapex) y mta (fillapex) en premolares inferiores unirradiculares extraídos

Abstract

Introduction: The purpose of this study was to determine in vitro the apical leakage endodontic sealers using two cement sealers, one based on calcium hydroxide (Sealapex) and another based MTA (Fillapex) in 60 extracted single-rooted mandibular premolars. Methods: Each tooth was subjected to a cursory cleaning process organic tissue, the teeth were standardized to a length of 16mm from tip by diamond disks, biomechanics preparation was performed using the technique step back, separated random samples into three groups, two of 30 pieces each and a group of 5 pieces for controlling ink penetration. The lateral condensation technique using Sealapex in the first 30 and MTA Fillapex in the other 30 are used for sealing of 60 pieces. The pieces were submerged in individual dispensers with ink for 7 days and were subjected to a process of diaphanisation. Each piece was evaluated by digital microscopy (MicroCapture) with a 20x objective recording length in millimeters apical leakage. Results: There was no statistically significant difference in the apical leakage between the MTA (Fillapex) and calcium hydroxide (Sealapex)
