OBJECTIVE: The purpose of this study was to compare shear bond strengths (SBS) of two new fluoride-releasing bonding systems with a conventional bonding system. MATERIALS AND METHOD: Fifty-one caries-free mandibular premolars and fifty-one mandibular molars were randomly divided into 3 groups of 17, and metal brackets and molar tubes were bonded. Group 1 (premolars) and Group 4 (molars) used conventional bonding with Transbond XT primer. The teeth in Group 2 (premolars) and Group 5 (molars) were bonded using Clearfil S3 Bond Plus. Group 3 (premolars) and Group 6 (molars) were bonded using Opal Seal Kit. A universal testing machine was used to determine the SBS. Adhesive remaining after debonding was also assessed. RESULTS: Clearfil S3 Bond Plus demonstrated significantly greater SBS values than Transbond XT and Opal Seal Kit (p=0.014 and p=0.009, respectively) in premolars. For molars, Opal Seal Kit yielded the lowest SBS values among all tested adhesive systems (p<0.01). The Kruskal-Wallis test showed no significant differences in the Adhesive Remnant Index (ARI) scores (χ2 = 6.92, p = 0.23). CONCLUSION: All adhesives exhibited adequate SBS values, but molar tubes bonded with Opal Seal exhibited lower SBS values than those obtained for the conventional bonding system and Clearfil S3 Bond Plus. According to the findings of the study, Clearfil S3 Bond Plus could be of greater advantage due to its greater bond strength.
