Summary

The aim of this study is through a randomized clinical trial, double blind, splith-mouth, evaluate the retention rate of restorative protocols of Non-carious cervical lesion. The presence of gingival displacement with a retraction cord (yes or no) and the category of adhesive system (etch-and-rise and self-etching) will be evaluated. Data will be collected, tabulated and submitted to statistical analysis.
