Clinical evaluation of a self-etch adhesive in non-carious cervical lesions

Purpose: To evaluate the clinical performance of a self-etching adhesive in Class V non-carious lesions with and without acid etching procedures. Methods: A total of 125 Class V non-carious cervical lesions (NCCL) with incisal or occlusal margins in enamel and gingival margins in dentin/cementum were selected and restored with Clearfil SE Bond self-etch adhesive and Clearfil APX resin composite. All cavities were restored using two techniques; after etching the whole cavity for 20 seconds and without acid etching (control). The restorations were evaluated at baseline. 1- and 2-year using modified USPHS criteria. Results: No loss of restorations was recorded after 1 and 2 years for the two restorative techniques. There was no significant difference between the baseline and 2-year results for any of the tested technique. However, restorations made after acid etching showed less marginal discoloration at the enamel margins. (Am J Dent 2008; 21:327-330).
