To investigate the effects of different polishing methods on the surface microstructure and roughness of teeth following initial periodontal treatment.
Teeth were divided into three groups (silica onegloss, polishing disc, and polishing strip) in vitro. Tooth surface microstructure was characterized via scanning electron microscopy. Roughness was measured by profilometry and laser scanning confocal microscopy (LSCM). According to the in vitro results, one group was chosen for further clinical trials. Effects of the chosen polishing method on patient plaque control and satisfaction were assessed via plaque staining and visual analog scale (VAS).
Electron microscopy results revealed that the polishing disc group had smoother roots and crowns than did the other two groups. Roughness analysis revealed that the crown roughness with the polishing disc and silica onegloss was lower, and the root roughness with the polishing disc was the lowest (p < .05) The LSCM results showed that the pigment deposition depth with the polishing disc and silicon onegloss in the crowns and roots were significantly lower than those with the other two methods (p = .000). The polishing effect of the polishing disc was best among the three groups. Clinical trials were performed to verify the polishing disc effects. Plaque staining results showed that the decrease in plaque in the polishing disc group was greater than that of the rubber cup group (p = .020), which was similar to the results of LSCM. The VAS results showed that the polishing disc made teeth feel smoother, similar to the results of the roughness detection, and the procedure was more comfortable (p < .05). However, there was no significant difference between the two groups regarding foreign body sensation during pronunciation (p = .178).
Combining in vitro and in vivo evaluations, the use of a polishing disc following periodontal treatment yielded superior polishing effects on teeth and was better accepted by patients.
研究不同抛光方法对牙周治疗初始后牙齿表面微观结构和粗糙度的影响。
体外将牙齿分为三组（二氧化硅抛光条、抛光片、抛光带）。通过扫描电子显微镜对牙面微观结构进行特征描述。通过轮廓仪和激光扫描共聚焦显微镜（LSCM）测量粗糙度。根据体外结果，选择一组进行进一步的临床试验。通过菌斑染色和视觉模拟评分（VAS）评估所选抛光方法对患者菌斑控制和满意度的影响。
电子显微镜结果显示，抛光片组的根面和冠面比其他两组更光滑。粗糙度分析显示，抛光片和二氧化硅抛光条的冠部粗糙度较低，抛光片的根部粗糙度最低（p<0.05）。LSCM 结果表明，抛光片和硅酮抛光条在冠部和根部的色素沉积深度明显低于其他两种方法（p=0.000）。抛光片在三组中的抛光效果最好。进行临床试验以验证抛光片的效果。菌斑染色结果显示，抛光片组的菌斑减少量大于橡胶杯组（p=0.020），与 LSCM 结果相似。VAS 结果显示，抛光片使牙齿感觉更光滑，与粗糙度检测结果相似，且该过程更舒适（p<0.05）。然而，两组在发音时异物感方面没有显著差异（p=0.178）。
结合体外和体内评估，牙周治疗后使用抛光片对牙齿有更好的抛光效果，且更受患者接受。
