Influences of Different Temporary Cement on Retention Rate of Temporary Crowns

Study Overview
=================
Brief Summary
-----------------
The aim of this study is through a randomized clinical trial, double blind, split-mouth, evaluate the success rate (retention rate and dental sensibility) of temporary dental crown cemented on vital teeth. The composition of the cement (Based on calcium hydroxide; and based on mineral trioxide aggregate) will be evaluated. Data will be collected, tabulated and submitted to statistical analysis.

Detailed Description
-----------------
The confecction of temporary prosthesis is a fundamental step in the prosthetic process of definitive total crowns. The temporary cementation should provide sufficient retention between the intervals of the consultations, be biocompatible and not present high solubility. The aim of this study is through a randomized clinical trial, double blind, splithmouth, evaluate the success rate (retention rate and dental sensibility) of temporary dental crown cemented on vital teeth. The composition of the cement (Based on calcium hydroxide; and based on mineral trioxide aggregate) will be evaluated. Twenty participants with at least two vital teeth with the need to confection of definitive total crowns (each participant) will be selected who present. The teeth will be randomly divided into 2 different groups according to the temporary cement composition (Based on calcium hydroxide; and based on mineral trioxide aggregate). Data will be collected, tabulated and submitted to statistical analysis
