Title

COMPARISON OF TWO METHODS FOR ELIMINATING THE BLEACHED ENAMEL SURFACE ROUGHNESS

Pages

  115-122

Abstract

 Introduction: VITAL BLEACHING technique is an effective method for reducing the teeth discolorations. The results of previous studies have shown that carbamide peroxide causes ENAMEL SURFACE ROUGHNESS, so the ENAMEL stain susceptibility increases. The purpose of this study was to compare two methods for elimination of the bleached ENAMEL SURFACE ROUGHNESS.Materials & Methods: In this Parallel interventional study, 60 sound bovine insicors, (5x5x10 mm) were selected. After 14 days of VITAL BLEACHING with 20% opalescence gel, the specimens were randomly divided into three groups of 20; i Bond group: the ENAMEL surface was covered by a self etch adhesive (i Bond); FLUORIDE group: the ENAMEL surface was polished by a rubber cap and was treated by 2.7% Acidulated phosphate FLUORIDE; Control group: no surface treatment was, done. In order to evaluate the lasting of each method, half of the specimens in each group were thermocycled. Data were analyzed using Kruskal-Wallis and Mann-Whitney tests (α=0.05).Results: The control group revealed a higher degree of roughness than i bond and FLUORIDE groups before thermo cycling (P<0.05). No significant difference was observed in roughness degree between i Bond and FLUORIDE group before thermocycling (P>0.05). The FLUORIDE group revealed a lower roughness degree than the other groups after thermocycling (P<0.05).Conclusion: For prevention of ENAMEL stain susceptibility after VITAL BLEACHING, polishing with rubber cap and FLUORIDE is an effective method for elimination of the ENAMEL SURFACE ROUGHNESS.
