Hybrid-coat联合树脂充填治疗敏感型楔状缺损的临床疗效观察

Clinical observation of the efficacy of Hybrid coat combined with composite resin for restoring hypersensitive wedge-shaped defect

目的 :研究Hybrid-coat联合树脂充填治疗敏感型楔状缺损的临床疗效。方法 :选择2016年7月—2016年12月在上海交通大学医学院附属第九人民医院口腔综合科就诊的敏感型楔状缺损患者70例,共159颗患牙,随机分为2组。联合组35例患者,81颗患牙采用Hybrid-coat脱敏后,复合树脂充填治疗楔状缺损。直接充填组35例患者,78颗患牙直接使用复合树脂充填。2组经过不同方式治疗后,采用SPSS 13.0软件包对各组患者在统一临床检查标准下的有效率(术后即刻,术后1、3、6个月复查)进行统计学分析。结果:2组在树脂充填后,Hybrid coat联合树脂充填组在术后3个月和术后6个月分别有1颗和2颗牙充填体脱落,直接充填组在术后6个月有2颗牙充填体脱落,2组差异无统计学意义。Hybrid coat联合树脂充填组术后即刻、术后1、3、6个月的脱敏有效率分别为91.36%、88.89%、79.01%和70.37%,均高于直接充填组分别为78.21%、76.92%、69.23%和61.54%;术后即刻和术后1个月,2组差异有统计学意义(P<0.05);术后3个月和6个月,2组差异无统计学意义。结论:Hybrid-coat联合复合树脂充填治疗敏感型楔状缺损有良好疗效,早期能明显改善牙敏感症状。

PURPOSE： The purpose of this study was to explore the effect of Hybrid-coat combined with composite resin filling on reducing hypersensitivity of dental wedge-shaped defect. METHODS： Seventy cases, 159 teeth with sensitive wedge-shaped defects were selected. The patients were randomly divided into 2 groups and treated as below： 35 cases, 81 teeth in group A were treated with Hybrid-coat combined with composite resin; 35 cases,78 teeth in group B were treated with composite resin directly. After treatments, the effective rates under clinical examination standard（immediately, 1, 3 and 6 months after filling） in both groups were collected and statistically analysed with SPSS 13.0 software package.RESULTS： In group A, one and 2 teeth fillings fell off 3 months and 6 months after treatments,respectively. In group B,2 teeth fillings fell off 6 months after operation. There was no significant difference between the two groups. The effective rate of desensitization was 91.36%, 88.89%, 79.01% and 70.37%, respectively, which was higher than those of group B（78.21%, 76.92%, 69.23% and 61.54%, respectively）. There was significant difference between the two groups immediately and 1 months after treatment（P 〈0.05）, but there was no significant difference between the two groups 3 months and 6 months after treatment. CONCLUSIONS： Hybrid-coat combined with composite resin is effective in reducing sensitivity of wedge-shaped defects.
