title: Immediate and 24-hour bond strengths of two dental adhesive systems to three tooth substrates.
abstract: Bond strengths of bonded composite resins to tooth substrates vary depending on when they were measured. Most bond strengths reported in the literature are a result of one hour, 24-hour, or longer periods of time that do not simulate actual clinical practice when occlusal adjustment and finishing and polishing procedures are performed within seconds after restoration placement. There are many different ways to measure the bond strength of direct esthetic restorations to various dental substrates. This research uses a method published previously that compares immediate and 24-hour bond strengths of a single-bottle dental adhesive and a self-etching primer adhesive to prepared enamel, unprepared enamel, and prepared dentin substrates. Significant differences were found between immediate and 24-hour bond strengths, but there were essentially no differences between substrates or adhesives.
