Abstract：
UNASSIGNED: To evaluate and compare the effect of diode laser assisted bleaching, ultrasonic scaling and powered tooth brushing on surface roughness and bacterial adherence on class V cavities restored with composites.
UNASSIGNED: A total of one hundred and twenty samples (40 samples each of Brilliant Everglow, Beautifil II and Heytec-N) were prepared in standardized stainless steel molds. The samples were further subdivided into four subgroups i.e. one control group (without any intervention) and three experimental groups - diode laser assisted bleaching, ultrasonic scaling and powered tooth brushing consisting of 10 sample each. Surface roughness was measured quantitatively with the help of 3D Optical Profilometer. For bacterial adherence analysis S. mutans strain (ATCC 25175) was cultured in BHI medium and samples were evaluated for the presence of viable bacteria using the Colony Forming Unit (CFU) count. Results obtained were then tabulated and subjected to statistical analysis.
UNASSIGNED: Diode laser bleaching caused a significant increase in surface roughness and bacterial adherence with lowest mean change exhibited by Heytec-N followed by Beautifil II and highest by Brilliant Everglow group. Similarly, Ultrasonic scaling increased the surface roughness of all the three tested samples with significant difference between the groups. Powered tooth brushing had no effect on the surface roughness and bacterial adherence of the tested composites.
UNASSIGNED: Diode assisted laser bleaching and ultrasonic caused significantly higher surface roughness and bacterial adherence values for all the tested composites. It may therefore be recommended to do finishing and polishing of restorations after such procedures.

摘要：
■为了评估和比较二极管激光辅助漂白的效果，用复合材料修复的V类腔上的表面粗糙度和细菌粘附上的超声波缩放和电动刷牙。
■总共一百二十个样本（每个40个样本，BeautifilII和Heytec-N）在标准化的不锈钢模具中制备。将样品进一步细分为四个亚组，即一个对照组（无任何干预）和三个实验组-二极管激光辅助漂白，超声波缩放和电动刷牙，每个10个样本。借助3D光学轮廓仪定量测量表面粗糙度。对于细菌粘附分析,将变异链球菌菌株(ATCC25175)在BHI培养基中培养,并使用菌落形成单位(CFU)计数评估样品中活细菌的存在。然后将获得的结果制表并进行统计分析。
■二极管激光漂白导致表面粗糙度和细菌粘附力的显着增加，Heytec-N表现出最低的平均变化，其次是BeautifilII，最高是BrilliantEverglow组。同样，超声结垢增加了所有三个测试样品的表面粗糙度，两组之间存在显着差异。动力刷牙对测试复合材料的表面粗糙度和细菌粘附没有影响。
■二极管辅助的激光漂白和超声波导致所有测试的复合材料的表面粗糙度和细菌粘附值明显更高。因此，建议在此类程序后对修复体进行精加工和抛光。
