摘　　要：目的:分析应用断冠再接的方法治疗恒前牙外伤冠折的效果及对口腔卫生状况的影响。方法:选取我院2019年1月—2020年6月收治的100例(131颗患牙)恒前牙外伤冠折患者,采用随机数字表法分为试验组(66颗牙)与对照组(65颗牙),每组50例,对照组使用复合树脂直接修复方式治疗,试验组使用断冠再接方式治疗,持续随访12个月,比较两组冠折再接成功率、口腔卫生状况(菌斑控制情况、牙周指数、牙石指数分度、龈沟探诊深度)。结果:随访6、12个月,试验组的冠折再接成功率分别为100.00%、95.45%,对照组分别为92.31%、76.92%,组间对比差异有统计学意义(P<0.05);随访3个月,两组菌斑控制情况、牙周指数、牙石指数分度、龈沟探诊深度比较,差异无统计学意义(P>0.05);随访6、12个月,试验组患者菌斑控制情况、牙周指数分值、牙石指数分度、龈沟探诊深度均低于对照组,差异有统计学意义(P<0.05)。结论:针对恒前牙外伤冠折患者,采取断冠再接的成功率较高,且可改善患者的口腔卫生状况。Objective To investigate the effect of applying the method of broken crown reattachment in the treatment of traumatic crown fracture of permanent anterior teeth and its influence on oral hygiene.Methods A total of 100 patients(131 teeth)with permanent anterior teeth trauma and crown fractures admitted to our hospital from January 2019 to June 2020 were selected as the research objects,and they were divided into the experimental group(65 teeth)and the control group(65 teeth)by random number table method,50 cases in each group,the control group used composite resin direct restoration method,and the experimental group used broken crown reconnection method.The follow-up continued for 12 months,the success rate of crown fracture reconnection and oral hygiene status(plaque control,periodontal index,calculus index indexing,and probing depth of gingival sulcus)were compared between the two groups.Results The success rates of crown fracture reconnection in the experimental group were 100.00%and 95.45%,and the control group was 92.31%and 76.92%,the differences between the groups were statistically significant(P<0.05).After 3 months of follow-up,there was no significant difference in plaque control,periodontal index,calculus index indexing and probing depth of gingival sulcus between the two groups(P>0.05).After 6 and 12 months of follow-up,the plaque control,periodontal index score,calculus index,and probing depth of gingival sulcus in the experimental group were lower than those in the control group,and the differences were statistically significant(P<0.05).Conclusion For patients with traumatic crown fractures of permanent anterior teeth,the success rate of broken crown reattachment is high,which can significantly improve the oral hygiene of patients.
