Two PMDM‐based dentine bonding agents and a microfilled composite were used to restore a total of forty non‐undercut caries‐free cervical abrasion lesions without enamel etching. Restorations were evaluated over one year and the loss rate calculated using a life table analysis. Marginal staining was assessed from colour photographs on a continuous linear rating scale. After one year, 5 per cent of Tenure bonded restorations were lost compared with 52 per cent of Mirage bonded restorations. Slight marginal staining was evident around Tenure bonded restorations after one year.
