Clinical evaluation of three adhesive systems in class V carious lesions

Abstract

Purpose The purpose of this study was to evaluate the clinical performance of three types of adhesive systems (Futurabond universal adhesive in a self-etch mode, Tetric N-bond self-etch adhesive, and Single bond universal adhesive in a total etch mode) in class V carious lesions over 1 year. Materials and methods A total of 20 patients with three carious cervical lesions were participated in this study after obtaining informed consent. A total of 60 restorations were placed. The distributions of adhesive materials and the teeth locations were randomized. Cavities were prepared limited to just removal of carious lesions with incisal and gingival margins in enamel and beveling of incisal cavosurface margin. All adhesives were applied following manufacturer's directions. All cavities were restored with Grandio SO composite resin following manufacturer's directions. Finishing and polishing was performed using finishing burs and polishing discs. Each restoration was clinically evaluated at baseline (24 h), 6 months and 1 year for retention, margin integrity, margin discoloration, secondary caries, and postoperative sensitivity using modified United state public health service (USPHS) criteria. Results The recall rate was 100% after 1 year. Also the retention rate for all restorations was 100% after 1 year. Using χ2-test, there was no statistically significant differences between the tested groups at all evaluation periods regarding marginal adaptation, marginal discoloration, and postoperative sensitivity (P > 0.05). None of restoration had secondary caries at any evaluation period. Conclusion Within the limitation of this short-term evaluation, there was no significant clinical difference between adhesives. Clinical significances All tested adhesive systems achieved excellent results after 1 year of clinical service.
