Detailed notes

- Objective: To evaluate the influence of a dentin desensitizer (Smartprotect Desensitizer) and a diode laser (Scorpion Dental Optima) application on the bond strength of a composite resin material to dentin. Background Data: Dentin-hypersensitivity treatments may influence the bond strength to dentin. Materials and Methods: Thirty extracted caries-free, erupted permanent third molars were used in this study. Dentin-desensitizing agent and diode laser were applied onto the cervical dentin surfaces. Dentin surfaces that had received no treatment were used as control samples. Dentin bonding agent was applied according to the manufacturer's instructions, and the adhesion test was performed according to ISO TR 11405. Results: The following shear-bond strengths were obtained (mean values and standard deviations in MPa): control group, 11.73 +/- 3.85 MPa; desensitizer-applied group, 11.45 +/- 3.33 MPa; and diode laser-applied group, 10.52 +/- 2.52 MPa. Statistical analysis showed no significant influence of the variable, different hypersensitivity treatments on shear-bond strength to dentin [analysis of variance (ANOVA), Tukey HSD test, p > 0.05). The data in this in vitro explorative study suggest that the short-term use of diode lasers and dentin desensitizers may not further affect the shear-bond strength of subsequent composite resin restoration to dentin. Conclusions: Within the limitations of this in vitro study, further studies are needed examining the structural changes of treated dentin and its adhesion characteristics to adhesive restorative materials.
