树脂直接充填与嵌体修复治疗后牙牙体缺损的疗效

Efficacy of direct filling resin and inlay restoration in the treatment of posterior tooth defect

目的对比主要针对后牙牙体缺损治疗中树脂直接充填与嵌体修复技术应用效果进行。方法80例后牙牙体缺损患者作为研究对象,随机分为对照组和研究组,各40例。对照组行树脂直接充填法,研究组行嵌体修复法。比较两组临床疗效、牙本质敏感疗效、填充成功率、咀嚼效率和生活质量评分。结果研究组患者的总有效率97.5%(39/40)高于对照组的77.5%(31/40),差异具有统计学意义(P<0.05)。研究组患者牙本质敏感总有效率97.5%(39/40)高于对照组的80.0%(32/40),差异具有统计意义(P<0.05)。研究组和对照组患者治疗3个月后填充成功率分别为75.0%(30/40)、75.0%(30/40),比较差异无统计意义(P<0.05)。研究组治疗1年后填充成功率97.5%(39/40)高于对照组的80.0%(32/40),差异具有统计意义(P<0.05)。治疗后,两组患者生活质量评分和咀嚼效率均高于本组治疗前,且研究组患者生活质量评分和咀嚼效率明显高于对照组,差异具有统计意义(P<0.05)。结论通过使用嵌体修复治疗后牙牙体缺损,能够有效改善患者牙齿功能,填充成功率较高、提高牙齿敏感性,增加牙齿使用寿命,较树脂填充法临床治疗效率好。

Objective To compare the practical effect of direct filling resin and inlay restoration in the treatment of posterior tooth defect.Methods A total of 80 patients with posterior tooth defect as study subjects were randomly divided into control group and research group,with 40 cases in each group.The control group was treated with direct filling resin,and the research group was treated with inlay restoration.The clinical efficacy,efficacy of dentin sensitivity,filling success rate,chewing efficiency and quality of life score were compared between the two groups.Results The total effective rate 97.5%(39/40)of the research group was higher than 77.5%(31/40)of the control group,and the difference was statistically significant(P<0.05).The total effective rate of dentin sensitivity 97.5%(39/40)of the research group was higher than 80.0%(32/40)of the control group,and the difference was statistically significant(P<0.05).The filling success rate of the research group and control group after 3 months of treatment were 75.0%(30/40)and 75.0%(30/40),respectively,and the difference was not statistically significant(P<0.05).The filling success rate of the research group and control group after 1 month of treatment was 97.5%(39/40),which was higher than 80.0%(32/40)of the control group,and the difference was statistically significant(P<0.05).After treatment,the quality of life score and chewing efficiency of the two groups were higher than those before treatment,and the research group was obviously higher than the control group.All the difference was statistically significant(P<0.05).Conclusion Compared with direct filling resin,inlay restoration has better clinical efficacy on patients with posterior teeth defect,and it can effectively improve the patient’s tooth function and filling success rate,tooth sensitivity,increase tooth service life.
