Clinical evaluation of five adhesive systems

One hundred cervical "abrasion/erosion" lesions were restored in groups of twenty with All-Bond, Photobond, Denthesive, and Pertac dentin adhesives with resin composite, and Geristore resin-based material. The mean patient age was 63 years. All but seven restoration sites were examined for up to approximately 14 months, and the cumulative retention rates of restorations calculated. At the end of the observation period, the percentage of restorations retained was; All-Bond 69.6%, Photobond 78.2%, Denthesive 42.8%, Pertac 7.5%, Geristore 71.8%, which was in approximate quantitative agreement with laboratory bond strength studies. The relationship of laboratory bond strength tests to clinical performance, and the influence of patient age on the clinical results, are discussed.
