Influence of the Composition of Temporary Restorative Material on the Retention Rate and Sensitivity for Provisional Direct Restorations in Vital Teeth - Clinical Study Randomized

The confection of temporary direct restoration is still verry commom in dental clinic routine, either by the time required or by biological requirements.The temporary restorations must have sufficient retention and solubility between the consultation intervals to avoid displacement and infiltration; besides being biocompatible to avoid sensitivity. 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 direct restoration on vital teeth. The composition of the temporary material (based on Zinc-Oxide with Eugenol; and based on mineral trioxide aggregate) will be evaluated. Twenty-five participants with at least two vital teeth with the need to confection of direct restoration (each participant) will be selected. The teeth will be randomly divided into 2 different groups according to the temporary material composition (Based on Zinc-Oxide with Eugenol; and based on mineral trioxide aggregate). Data will be collected, tabulated and submitted to statistical analysis.
