This study was a clinical trial of a one-step, total priming and bonding system, Xeno III. Thirty restorations were placed in minimally invasive V-shaped, Class V cervical cavities. Immediately after placement, baseline records were made after restorations were assessed using modified Ryge/USPHS criteria. Subsequently, restorations were evaluated at recall intervals up to 18 months. Additionally, the measurement of tensile bond strength and the FE-SEM observation of resin-tooth interface were performed in vitro. At 18 months, all restorations were classified as clinically satisfactory and assigned with an Alpha rating. Tensile bond strength of Xeno III was not significantly different from that of Clearfil SE Bond. Resinenamel/dentin interface was very tight, with the presence of a very thin hybrid layer at the superficial dentin. Based on the results obtained, the Xeno III resin bonding system seemed promising as a one-step, self-etch adhesive.
