Clinical Trial 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.

Description:

Endodontically treated teeth present an increased risk of fracture and are usually related to extensive carious processes or trauma that promote major coronary destruction. In such situations, it may be necessary to indicate intra-radicular retainers, such as fiberglass pins, to retain the restorative material. 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. Twenty participants with at least two teeth with endodontic treatment with need intraradicular post cementation and confection of indirect dental crown (each participant) will be selected. The teeth will be randomly divided into 2 different groups according to resin cement composition (with and without mineral trioxide aggregate). Data will be collected, tabulated and submitted to statistical analysis.
