Evaluación de la microfiltración apical utilizando diferentes técnicas de obturación : revisión sistemática.

Abstract

INTRODUCTION: Obturation is the three-dimensional filling of the root canal system, it is a fundamental step to make a good seal, reducing the risk of microfiltration. OBJECTIVE: To assess the effectiveness of apical microfiltration using different obturation techniques through a literature review. MATERIALS AND METHODS: A qualitative, descriptive, non-experimental cross-sectional-retrospective research study, with a sample of 30 articles, of which a universe of 315 articles was observed. The same ones that were reviewed and analyzed according to the inclusion and exclusion criteria. RESULTS: The most used thermoplastic technique was Ultrafil, the resin-based cement was the most used in 56% and the least used was calcium hydroxide-based in 10%. The most used instrumentation technique was Step back and Universal Protaper, in measurement with stain the most used was methylene blue at 2%. CONCLUSIONS: It was observed within the whole search of the articles that there is not a significant difference between the 2 techniques of obturation.
