摘要
目的探究活髓牙冠修复后临时冠粘固剂对牙髓的影响。方法选择2018年7月~12月我院收治的活髓牙冠修复患者共60例(81颗活髓牙),采用随机数字表法分为观察1组(20例,29颗活髓牙)、观察2组(20例,28颗活髓牙)和对照组(20例,24颗活髓牙)。对照组采用氧化锌丁香酚水门汀粘固,观察1组采用玻璃离子水门汀粘固,观察2组采用藻酸盐弹性印模材料,对比三组视觉模拟评分(VAS)与并发症状况。结果三组临时冠粘固后1、7 d VAS评分比较,差异有统计学意义(P<0.05);观察1组临时冠粘固后1、7 d VAS评分低于观察2组和对照组,差异具有统计学意义(P<0.05);观察2组临时冠粘固后1、7 d VAS评分低于对照组,差异具有统计学意义(P<0.05);三组临时冠粘固后7 d VAS评分低于粘固后1 d,差异具有统计学意义(P<0.05)。三组冷热刺激反应与牙髓炎发生率比较,差异无统计学意义(P>0.05)。结论活髓牙冠修复后采用玻璃离子水门汀粘固临时冠可有效减轻牙齿敏感状况,并可减少牙髓并发症。
Objective To investigate the effect of temporary crown cement on the pulp after the restoration of the vital crown.Methods A total of 60 patients(81 live pulp teeth)were enrolled in our hospital from July to December 2018.The patients were randomly divided into observation group one(20 cases,29 live pulp teeth).Observation group two(20 cases,28 vital pulp teeth)and control group(20 cases,24 live pulp teeth).The control group was adhered with zinc oxide eugenol cement.The observation group one was cemented with glass ionomer cement,the observation group two used alginate elastic impression materials to compare the three groups of visual analogue scale(VAS)and complications.Results There was significant difference in VAS score between the three groups on the 1st and 7th d after temporary crown bonding(P<0.05).The VAS score of the observation group one was lower than that of the observation group two and the control group on the 1st and 7th d after temporary crown adhesion,the difference was statistically significant(P<0.05).The VAS scores of the observation group two were lower than that of the control group at 1st and 7 d after the temporary crown adhesion,the difference was statistically significant(P<0.05).The VAS score of the three groups on the 7th d after temporary crown bonding was lower than that on the 1st day after bonding,the difference was statistically significant(P<0.05).There was no significant difference between the three groups in the incidence of cold and heat stimulation and pulpitis(P>0.05).Conclusion The use of glass ionomer cement to fix the temporary crown after the restoration of the viable crown can effectively reduce the sensitivity of the teeth and reduce the complications of the pulp.
