Clinical performance of three dentine bonding agents in Class V abrasion lesions without enamel etching

Seventy-six Class V non-undercut abrasion lesions were restored with composite and either Dentine Adhesive,† Bondlite,‡ ; or Dentin Bonding Agent ,§ without enamel etching. Restorations were trimmed and polished after approximately three weeks, and evaluated for integrity and marginal staining. Recall evaluations were carried out at three months, six months and one year. The cumulative loss incidence at one year for Dentine Adhesive, Bondlite , and Dentin Bonding Agent was 83 per cent, 25 per cent, and 33 per cent, respectively. Restorations with Dentin Bonding Agent had the most severe marginal staining, while Bondlite restorations had least marginal staining.
