摘要
目的:观察根管填充联合冠修复术治疗乳牙牙体大面积缺损的临床疗效。方法:回顾性分析2017年1月至2018年1月温岭市第四人民医院收治的乳牙牙体大面积缺损160例的临床资料,患儿均接受根管填充术治疗,根据采用的不同术后修复方式分为两组,观察组(80例)给予金属预成冠修复术,对照组(80例)给予树脂填充修复。比较两组牙龈健康情况(牙龈指数)及修复效果,包括有无继发龋、牙龈情况(有无充血)、有无食物嵌塞;随访1年,比较两组牙体情况(边缘密合性、邻接关系)以及修复安全性(修复体情况、磨耗情况)。结果:修复前,两组牙龈指数[(0.76±0.41)比(0.73±0.32)]差异无统计学意义(P>0.05);修复后,观察组的牙龈指数为(0.86±0.55),明显低于对照组的(1.35±0.62)(t=5.288,P<0.001);观察组无继发龋、食物嵌塞等,牙龈出血1例;对照组出现继发龋8例、食物嵌塞4例、牙龈出血9例,观察组明显低于对照组(χ^(2)=6.826,P<0.05)。随访1年发现,观察组黏合合格者79例(98.75%),咬合合格者78例(97.50%);对照组黏合合格者70例(87.50%),咬合合格者69例(86.25%);两组差异均有统计学意义(χ^(2)=7.907、6.781,均P<0.05);观察组边缘密合性成功率、邻接关系成功率以及修复体情况、磨耗情况等成功率均明显高于对照组(98.75%比86.25%、100.00%比87.50%、100.00%比85.00%、98.75%比83.75%),差异均有统计学意义(χ^(2)=9.009、10.666、12.973、11.272,均P<0.05)。结论:采用根管填充联合冠修复术治疗乳牙牙体大面积缺损,黏合合格及咬合合格成功率高,不良缺陷少,可减少食物嵌塞以及牙龈出血的发生,降低继发龋病风险,能较好的保护剩余牙体组织,维护正常咀嚼功能,有利于恒牙的萌出。
Objective To investigate the clinical efficacy of root canal filling combined with crown restoration in the treatment of large area defect of deciduous teeth.Methods The clinical data of 160 children patients with large area defect of deciduous teeth who received treatment in Wenling No.4 People's Hospital from January 2017 to January 2018 were retrospectively analyzed.All included children received root canal filling treatment.According to the different postoperative repair methods,these children were divided into two groups.In the observation group(n=80),repair with a prefabricated metal crown was performed.In the control group(n=80),resin filling repair was given.Gingival health(gingival index)and restoration effect,including secondary caries,gingival condition(congestion or not)and food impaction were compared between the observation and control groups.Tooth condition(marginal tightness,adjacency)and safety(restoration and abrasion)were compared between the two groups after 1 year of follow up.Results Before restoration,there was no significant difference in gingival index between the observation and control groups[(0.76±0.41)vs.(0.73±0.32),P>0.05].After restoration,gingival index in the observation group was significantly lower than that in the control group[(0.86±0.55)vs.(1.35±0.62),t=5.288,P<0.001].In the observation group,no secondary caries or food impaction was observed,and there was one case of gingival bleeding.In the control group,there were eight cases of secondary caries,four cases of good impaction,and nine cases of gingival bleeding.The incidence of adverse reactions in the observation group was significantly lower than that in the control group(χ^(2)=6.826,P<0.05).One-year follow-up results revealed that 79 cases(98.75%)were qualified in tooth bonding and 78 cases(97.50%)were qualified in tooth occlusion in the observation group,while 70 cases(87.50%)were qualified in tooth bonding and 69 cases(86.25%)were qualified in the occlusion in the control group.There were significant differences in qualified bonding and occlusion between the two groups(χ^(2)=7.907,6.781,both P<0.05).The success rate of marginal tightness,the success rate of adjacency,restoration and abrasion in the observation group were higher or superior to those in the control group(98.75%vs.86.25%,100.00%vs.87.50%,100.00%vs.85.00%,98.75%vs.83.75%)(χ^(2)=9.009,10.666,12.973,11.272,all P<0.05).Conclusions Root canal filling combined with crown restoration in the treatment of large area defect of deciduous teeth has a high success rate of qualified bonding and occlusion,less adverse defects,low incidence of food impaction and gingival bleeding,decreases the risk of secondary caries,protects the remaining tooth tissue,maintains normal chewing function,and is conducive to the eruption of permanent teeth.
