Background: The growing demands for esthetic restorations have stimulated intensive research in the field of adhesive dentistry. Dental adhesive systems are used to promote adhesion between composite resins and dental structure. In the fundamental principles of adhesion, the primary mechanism contributing to the formation of adhesion is micromechanical bonding between the restoration and the tooth. The bond strength of self-etching adhesives to dentin was found to be almost equal to that of total-etch adhesives. The aim of the present prospective, double-blind, randomized controlled clinical trial was to evaluate and compare the clinical performance of two self-etch adhesive systems with total-etch adhesive system in noncarious cervical lesions (NCCLs). Materials and Methods: In each patient, three teeth were randomly assigned according to the adhesive system used to Group A (total-etch adhesive system), Group B (two-bottle self-etch adhesive system), and Group C (one-bottle self-etch adhesive system). The clinical efficacy of these adhesive systems was determined by evaluating the retention rate, marginal integrity, and postoperative sensitivity at the following three levels: baseline, 6 months, and 18 months by following the Modified USPHS criteria introduced by Vanherle et al. Results: In the present study, the retention rate at 18 month in Group A, Group B, and Group C of 96%, 92%, and 92% was observed, respectively. A marginal integrity at 18 months was 88%, 80%, and 84% for Group A, Group B, and Group C, respectively. Postoperative sensitivity at 18 months was 16%, 12%, and 12% for Group A, Group B, and Group C, respectively. Conclusion: The clinical performance of total-etch and self-etch adhesive systems in NCCLs did not differ significantly with regard to the evaluated parameters – retention, marginal integrity, and postoperative sensitivity.
