Brief Summary
The aim of this study is through a randomized clinical trial, double blind, splithmouth, evaluate the success rate (post or dental crown displacement; fracture of the core/post/crown; marginal integrity and absence of endotontic alterations) of definitive indirect crowns un endodontically treated teeth. The composition of the resin cement (with and without mineral trioxide aggregate) will be evaluated. Data will be collected, tabulated and submitted to statistical analysis.
