Materials and Methods: Eighty dentin specimens were prepared from freshly extracted human third molar teeth and were classified, randomly (n = 20). Half of groups were treated with calcium phosphate based Teethmate Desensitizer and then Panavia V5, RelyX Ultimate (containing self-etch primer), Panavia SA, and RelyX U200 self-adhesive resin cements were luted to all dentin surfaces. All specimens were stored in an incubator at 37 degrees C for 24 h. Shear bond strength was tested by a universal test machine at a 0.5 mm/min crosshead speed. The data were analyzed with a statistical program. Two-way ANOVA was used for statistical differences (P<.05). Dentin surfaces were examined with scanning electron microscopy (SEM) at x5000 and x10000 magnifications. Results: The higher shear bond values were observed in the groups with Teethmate Desensitizer applied and cemented with self-etch (16.05 +/- 6.24 and 14.73 +/- 4.75), whereas the lowest bonding values were observed in the groups with self-adhesive resin cement without Teethmate Desensitizer (3.73 +/- 0.77 and 5.85 +/- 4.19; P<.001). As the main effect of the treatment, the bond strength was 9.39 +/- 6.04 in the control group, whereas it was 13.49 +/- 5.44 in the Teethmate applied groups (P<.05) Conclusions: Calcium phosphate desensitizer did not adversely effected shear bond strength of self-etch/adhesive resin cements to dentin. It even significantly increased the shear bond strength of self-adhesive resin cements.eninfo:eu-repo/semantics/closedAccessCalcium Phosphate DesensitizerSelf-Etch Resin CementAdhesive Resin CementShear Bond StrengthArticle131N/AQ38590WOS:000796024300012
