In Vitro Comparison of the Effectiveness of a Resin Infiltration System and a Dental Adhesive System in Dentinal Tubule Penetration

Objective: The aim of this study was to assess and compare the dentin tubule penetration effectiveness of a dental adhesive and a resin infiltration system used with two different surface treatments. Methods: Dentin specimens were obtained from 42 impacted lower right wisdom tooth, 2 of these specimens were used to detect the effects of surface treatments. Two different surface treatments (37% phosphoric acid and 17% EDTA) were applied to the samples to compare the dentin tubule penetration effectiveness of a dental adhesive –which had been using for treatment of dentin hypersensitivity- (Adper Single Bond 2, 3M, Germany) and a resin infiltration system (ICON, DMG, Germany). Scanning electron microscopy was used to investigate the tubule penetration effectiveness. For statistical analysis, Kruskal Wallis and Mann Whitney U and One Way Analysis of Variance (ANOVA) and Tukey HSD tests were used.Results: ICON had shown significantly more resin penetration intensity and more resin penetration depth than Adper Single Bond 2 (p<0.05). Phosphoric acid treatment groups had shown significantly more penetration intensity than EDTA treated groups (p=0.001). Conclusion: According to the results of this study, it can be concluded that tubuler penetration effectivenes of ICON resin infiltration system is better than Adper Single Bond 2 adhesive system.
