EFFECT OF DENTINE DESENSITIZING AGENTS ON THE BOND STRENGTH OF COMPOSITE RESIN TO DENTINE.
Journal Title: IJSR-International Journal Of Scientific Research - Year 2018, Vol 7, Issue 6
Abstract
Hypersensitivity is a common clinical multi-etiological problem. Many desensitizing treatments are there to overcome hypersensitivity. The aim of the study is to evaluate the effect of desensitizing dentifrice containing sodium calcium phosphosilicate and Diode laser on the tensile bond strength of composite to dentine. Materials and Methods: Thirty sound human molars were used. Enamel was wet abraded to expose flat dentin surfaces and polished with sandpaper. The specimens were then divided into three groups (n = 10) based on the type of dentin-desensitizing treatment given. Group 1- was the control group where no desensitizing agent was used. Group 2-was treated with desensitizing dentifrice containing sodium calcium phosphosilicate. Group 3- was treated with Diode laser. Afterwards, the desensitized specimens were treated with one step self-etch adhesive (Tetric N Bond) according to manufacturer's instructions and composite micro cylinders were packed. The specimens were then examined for tensile bond strength using universal tensile machine. Statistical analysis: The recorded values were subjected to statistical analysis using the SPSS software. One-way ANOVA, and Post-hoc Tukey HSD test were performed to evaluate the tensile bond strength values. For the entire evaluation, P < 0.05 was considered to be statistically significant. Results: Higher tensile bond strength was seen in the control group when compared with the experimental groups Conclusion: Based on the results of this study, dentifrice and Laser pretreated dentin has lower tensile bond strength with resin composites as compared to dentin that is untreated
