摘　　要：目的:研究不同厚度3M大块树脂充填治疗前磨牙V类洞的修复效果和美学效果。方法:选取2019年6月-2021年6月笔者医院115例接受3M光固化大块复合树脂充填治疗的前磨牙V类洞患者为研究对象,按照就诊顺序将患者编号,然后采用随机数字表均分为观察组57例(患牙92颗)和对照组58例(患牙85颗),观察组采用一次性充填修复,对照组采用分层充填修复,比较两组修复效果、边缘密合度、牙周健康状况及外观满意度。结果:两组色泽协调性、边缘密合性、表面形态和继发龋分级差异无统计学意义(P>0.05),观察组边缘着色满意度高于对照组,差异有统计学意义(P<0.05);两组术后1、6、12个月时修复体与牙体间隙边缘密合度比明显升高(P<0.05),且观察组术后1、6、12个月时间隙边缘密合度比低于对照组,差异有统计学意义(P<0.05);两组术后12个月时探诊深度(Probing depth,PD)、附着指数(Attachment level,AL)及出血指数(Bleeding index,BI)明显降低(P<0.05),且两组间PD、AL和BI比较差异无统计学意义(P>0.05);术后12个月时,观察组患牙颜色视觉模拟法(Visual analogue scale,VAS)评分明显高于对照组(P<0.05),两组整体轮廓和表面形态VAS评分差异无统计学意义(P>0.05)。结论:3M大块充填树脂治疗前磨牙V类洞时采用一次性充填有利于修复体与牙体间隙比,提升修复体边缘密合度,改善美观度,治疗效果较分层充填具有明显优势。Objective To study the restoration effect and aesthetic effect of different thicknesses of 3M bulk resin filling in the treatment of class V cavities of premolars.Methods 115 patients who received light-curing 3M bulk composite resin filling for class V cavities of premolars in the hospital between June 2019 and June 2021 were selected as samples.The patients were numbered according to the order of treatment,and then they were divided into observation group(57 cases,92 affected teeth)and control group(58 cases,85 affected teeth)by the random number table method.The observation group adopted onetime filling restoration while the control group was treated with layered filling restoration.The restoration effect,marginal fit,periodontal health and appearance satisfaction were compared between the two groups.Results There were no significant differences in color coordination,marginal fit,surface morphology and secondary caries grading between the two groups(P>0.05),and the satisfaction of edge coloring in observation group was higher than that in control group(P<0.05).At 1,6 and 12 months after surgery,the restoration-to-tooth gap ratio in the two groups was significantly increased(P<0.05),and the gap ratio in observation group was lower than that in control group at 1,6 and 12 months after surgery(P<0.05).The probing depth(PD),attachment index(AL)and bleeding index(BI)were significantly decreased in both groups at 12 months after surgery(P<0.05),and there were no statistical differences in PD,AL and BI between the two groups(P>0.05).The score of color visual analogue scale(VAS)of the affected teeth in observation group at 12 months after surgery was significantly higher than that in control group(P<0.05),but there was no statistical significance in the overall contour VAS score or surface morphology VAS score between the two groups(P>0.05).Conclusion One-time filling in the treatment of class V cavities of premolars with 3M bulk resin is beneficial to improving the restoration-to-tooth gap ratio,enhancing the margina
