玻璃纤维桩树脂核用于上颌前牙区修复的美容效果及牙菌指数和稳固性分析

Cosmetic Results of Glass Fiber Post and Resin Core in Restoration of Maxillary Anterior Teeth and Analysis of Dental Plaque Index and Stability

目的:探讨玻璃纤维桩树脂核在上颌前牙区修复中的美容效果及牙菌指数和稳固性。方法:选取2017年5月至2019年6月本院收治的226例上颌前牙区修复患者,简单随机法分为对照组和研究组各113例,对照组给予金属桩核修复,研究组给予玻璃纤维桩树脂核修复,比较两组美容效果、牙周指标、咀嚼功能及抗折性能。结果:两组修复前、修复后3个月、12个月红美学分数(PES)、白美学分数(WES)评分逐渐升高,且组间存在交互效应(P<0.05),其中修复后3个月PES、WES评分比较无显著差异(P>0.05),修复后12个月研究组PES、WES评分均高于对照组(P<0.05);修复后3个月研究组牙龈指数、出血指数、牙菌斑指数、探诊深度水平均低于对照组,且修复前后差值均明显高于对照组(P<0.05);研究组修复后12个月咀嚼功能优良率95.58%高于对照组的87.61%(P<0.05);随访2年,研究组桩折断、桩松动脱落发生率1.77%、3.54%均低于对照组的7.96%、11.50%(P<0.05)。结论:玻璃纤维桩树脂核应用于上颌前牙区修复中可提升美容效果,改善牙周指标,降低牙菌指数,促进稳固性。

Objective:To investigate the cosmetic results of glass fiber post and resin core in the restoration of maxillary anterior teeth,and analyze the dental plaque index and stability.Methods:A total of 226 patients who underwent a restoration of maxillary anterior teeth in the hospital from May 2017 to June 2019 were selected,and randomly divided into control group and study group,with 113 cases in each.The control group received restoration with metal post and core,while the study group received restoration with glass fiber post and resin core.Cosmetic results,periodontal indicators,masticatory function,and fracture resistance were compared between the two groups.Results:The pink esthetic scores(PES)and white esthetic scores(WES)of the two groups increased over time,with an interaction effect between groups(P<0.05).The above scores showed no significant difference at 3 months after restoration(P>0.05).The study group had higher PES scores and WES scores than the control group at 12 months after restoration(P<0.05).Gingival index,bleeding index,plaque index,and probing depth in the study group were lower than those in the control group at 3 months after restoration.The differences before and after restoration were significantly greater than those of the control group(P<0.05).The excellent and good rate of masticatory function in the study group at 12 months after restoration(95.58%)was higher than that in the control group(87.61%)(P<0.05).The incidence rates of post fracture,post loosening,and falling off in the study group during 2 years of follow-up(1.77%and 3.54%)were lower than those in the control group(7.96%and 11.50%)(P<0.05).Conclusion:The application of glass fiber post and resin core in the restoration of maxillary anterior teeth can improve the cosmetic results and periodontal index,reduce dental plaque index,and improve stability.
