The aim of this randomized, controlled, prospective clinical trial is to evaluate the performances of a universal adhesive in three different application modes, a self-etch adhesive and an etch\&rinse adhesive in restoration of non-caries cervical lesions. Thirty-four patients will receive restorations. Lesions will be divided into 5 groups according to adhesive systems and application modes: CU-SE: Clearfil Universal Bond Quick in self-etch mode, CU-SLE: Clearfil Universal Bond Quick in selective etch mode, CU-ER: Clearfil Universal Bond Quick in etch\&rinse mode, CSE: Clearfil SE Bond, TB: Tetric N-Bond. Restorations (Tetric N-Ceram composite) will be scored with regard to retention, marginal discoloration, marginal adaptation, recurrent caries and post operative sensitivity using modified USPHS criteria after 48 months. Two examiners who is not involved in the placement of restorations will conduct the evaluations. Descriptive statistics will be performed using Chi-square tests.
