Evaluation of Simulated Toothbrushing with different Dentifrices on Enamel Resin Infiltrated Teeth Surface Roughness and Gloss

摘要

To evaluate the effect of simulated toothbrushing with different dentifrices on surface roughness and gloss of resin-infiltrated enamel. Thirty human premolars were prepared to have white lesion on half of buccal enamel surface then received resin infiltration. The specimens were submitted to toothbrushing simulation with different relative dentin abrasion dentifrices. Surface roughness and gloss were measured before white lesion preparation and after simulated teeth brushing. The obtained data statistically analyzed using IBM SPSS Statistics 20 Software with one?way ANOVA followed by Tukey’s multiple comparison tests (P ≤ 0.05). There was a significant increase in surface roughness and gloss reduction for Icon resin infiltered enamel surface simulated teeth brushing with all dentifrices. Conclusions: Toothbrushing with different relative dentin abrasion (RAD) dentifrices increased the roughness and diminished the gloss of the resin infiltrated enamel surface.
