摘要/Abstract

摘要： 目的: 研究不同功率532 nm Nd:YAG激光照射对邻面去釉后釉质表面的影响。方法: 体外建立邻面去釉后牙齿样本模型,根据处理方式不同分为对照组、氟制剂组与不同功率激光联合增效剂组,釉质表面形貌通过扫描电子显微镜评估,平板计数法测定样本表面细菌黏附量。结果: 扫描电镜下2.2 W激光联合增效剂照射组釉质表面较其余组明显平滑。平板计数结果中除2.8 W及3.0 W激光组外,其余各组釉质表面的细菌黏附量均少于对照组(P<0.05),2.4 W激光组细菌黏附量最小,但与2.2 W激光组组间比较差异无统计意义(P>0.05)。结论: 2.2 W Nd:YAG激光联合增效剂照射可明显降低邻面去釉后釉质表面粗糙度及细菌黏附量。

Abstract: Objective: To evaluate the effect of 532nm Nd:YAG laser irradiation on enamel surface after interproximal enamel reduction. Methods: The tooth models with interproximal enamel reduction were established, and divided into control group, fluorine preparation group, and different power laser combined with synergist groups according to different treatment methods. The enamel surface topography was evaluated by scanning electron microscope (SEM). The amount of streptococcus mutans adhesion was measured by the plate count method. Results: The surface topographies measured by SEM in the 2.2 W laser irradiation group was significantly smoother compared to other groups. The amount of bacterial adhesion on the enamel surface in groups excluding the 2.8 W and 3.0 W laser groups was less than that of the control group (P<0.05), and the 2.4W laser irradiation group had the minimum amount of bacterial adhesion, but the difference was not statistically significant compared with the 2.2 W laser group (P>0.05). Conclusion: 2.2 W Nd:YAG laser irradiation combined with synergist can safely and significantly reduce the surface roughness and bacterial adhesion of enamel with interproximal enamel reduction.

Key words: Nd:YAG laser, interproximal enamel reduction, enamel surface, bacterial adhesion
