Abstract
Objective The purpose of this in vitro study was to evaluate the effect of filled-resin desensitizing agent on the prevention of dentin abrasion caused by tooth brushing. Materials and methods Forty root dentin segments were prepared from 40 extracted premolar teeth by using diamond bur cut and cementum layer removed. The 40 root dentin segments were treated with radiation and kept until use, and randomly assigned to 4 groups according to the agents treated the dentin surfaces. Group 1 was treated with filled-resin agent Seal&Protect™, group 2 with unfilled-resin Seal&Protect™ agent which had the same composition like group 1 but no filler, group 3 treated with another unfilled resin All-bond 2® and group 4 control group-untreated surfaces. Dentin abrasion was measured by a radiotracer technique using a modification of the ADA recommended method. After tooth brushing on the sample segments, which were mounted in V8 cross-brushing machine, the slurry was counted in a scintillation counter and calculated in net count per minute (cpm) and tested the differences by ANOVA. Results The results showed that there were significant differences in the amount of dentin lost among groups (p < .05). The lowest amount of dentin lost was found in the filled-resin Seal&Protect™ treated group. Conclusion The results indicate that filled-resin Seal&Protect™ desensitizing agent can reduce dentin abrasion in vitro and may be further used for the treatment of root hypersensitivity. However, this result should be confirmed by clinical trials.
