目的 探究纤维桩联合复合树脂及氧化锆烤瓷冠修复治疗根管治疗(RCT)后后牙楔状缺损(WSD)的效果.方法 选取2019年8月—2022年8月在新乡市口腔医院治疗的300例(300牙)RCT后后牙WSD患者,按随机数字表法分成A组(n=150)、B组(n=150).A组接受纤维桩联合复合树脂及氧化锆烤瓷冠修复治疗,B组接受金属烤瓷冠(PFM)联合金属桩核(MPC)修复治疗.对比2组修复成功率、修复效果、修复前后牙周健康指标[牙龈指数(GI)、菌斑指数(PLI)、牙周探诊深度(PD)]、龈沟液炎性因子[白细胞介素-6(IL-6)、白细胞介素-10(IL-10)、肿瘤坏死因子-α(TNF-α)]水平.结果 A组修复成功率为97.33%(146/150),高于B组的87.33%(131/150)(P＜0.05);A组边缘密合性、表面质地、颜色匹配均优于B组(P＜0.05);修复6个月后A组GI、PLI、PD较B组低(P＜0.05);修复1个月后A组龈沟液TNF-α、IL-6水平较B组低,IL-10水平较B组高(P＜0.05).结论 与PFM联合MPC修复治疗RCT后后牙WSD患者相比,应用纤维桩联合复合树脂及氧化锆烤瓷冠修复治疗更有助于提升修复成功率及修复效果,改善牙周健康,且对组织产生创伤更小.
Objective To investigate the restorations outcome of fibre post+composite resin+zirconia porcelain crown for patients with wedge-shaped defects(WSD)in posterior teeth after root canal therapy(RCT).Methods A total of 300 patients(300 teeth)with posterior WSD after RCT in our hospital(from August 2019 to August 2022)were selected and divided into group A(n=150)and group B(n=150)according to random number table method.Group A received composite resin+zirconia porcelain crown+fiber post repair treatment,while group B received porcelain fused to metal(PFM)+metal post core(MPC)repair treatment.The success rate of repair,the effect of repair,the periodontal health indicators before and after repair[gingival index(GI),plaque index(PLI),periodontal probing depth(PD)],and the levels of gingival creval fluid inflammatory factors[interleukin-6(IL-6),IL-10,tumor necrosis factor-α(TNF-α)]were compared between the two groups.Results The success rate of repair in group A was 97.33%(146/150),higher than 87.33%(131/150)of group B(P＜0.05).The edge tightness,surface texture and color matching of group A were better than those of group B(P＜0.05).After 6 months of repair,GI,PLI and PD in group A were lower than those in group B(P＜0.05).After one month of repair,the contents of TNF-α and IL-6 in gingival crevicular fluid of group A were lower than those of group B,and the contents of IL-10 were higher than those of group B(P＜0.05).Conclusions Compared with PFM+MPC in the treatment of posterior WSD patients after RCT,the application of composite resin+zirconia porcelain crown+fiber post repair is more helpful to improve the success rate and effect of repair,improve periodontal health,and cause less tissue trauma.
