Paper Abstract

Previous researches have discussed the importance of sealing the internal surface of the root canal after preparing it for posts or dowels, avoiding tubuli contamination by the oral environment. The purpose of this study was to investigate the effects of Neodymium-Yttrium-Aluminum-Garnet laser irradiation, associated or not with another materials, on the root inner walls after post space preparation. Forty single rooted endodontically treated teeth had theirs filings partially removed for prosthetics restoration, divided into 8 groups which received a coat of the following materials: group A: Copalite vanish; group B: Copalite vanish and laser; group C: Scothbond Multi-Purpose; group D: Scothbond Multi-Purpose and laser; group E: methylcianoacrilate; group F: methylcianocrilate and laser; group G: laser only; group H: control. The roots were placed in methylene blue dye and transversally cutted, then submitted to the analysis in the profile projector. So far we could observe that the Nd:Yag laser was able to enhance the sealing properties of the Scothbond Multi-Purpose.
