复合树脂加玻璃离子夹层修复老年牙根面龋的应用效果

摘要

目的：研究复合树脂加玻璃离子夹层修复老年牙根面龋的临床效果。方法选取本院2011年1月~2013年12月接收的180例(295颗)老年牙根面龋患者为研究对象，根据患者意愿将其分为三组。A组(91颗)采用玻璃离子进行治疗；B组(109颗)采用光固化复合树脂进行治疗；C组(95颗)采用复合树脂加玻璃离子夹层修复。比较三组患者治疗6、12个月后的成功率。结果治疗6个月后，A组成功率为93.41%，B组为77.06%，C组为95.79%，从高到低依次为C组>A组>B组，且A、C组显著高于B组(P<0.05)，A、C组比较差异无统计学意义(P>0.05)。治疗12个月后，A组成功率为76.92%，B组为65.14%，C组为94.74%，从高到低依次为C组>A组>B组，且C组显著高于A、B组(P<0.05)。结论对于老年牙根面龋患者，复合树脂加玻璃离子夹层修复的近远期疗效确切，值得临床推广应用。%Objective To study the clinical effect of composite resin and glass ion sandwich restoration on the root caries in the elderly. Methods 180 cases of the patients with geriatric root caries (295 teeth) admitted into our hospital from January 2011 to December 2013 were selected as the research object and divided into three groups according to the wishes of patients.The patients in group A (91 teeth) were treated with glass ion,the patients in group B (109 teeth) were treated with light-cured composite resin while the patients in group C (95 teeth) were treated with the technique of composite resin and glass ion sandwich restoration.The success rates were compared between the two groups after the treatment of 6 months and 12 months. Results Six months after the treatment,the success rate of group A was 93.41%, the success rate of group B was 77.06%and that of group C was 95.79%.The order of the success rate from high to low was group C>group A>group B.The success rate of group A and C was significantly higher than that of group B (P<0.05).There was no difference of statistical significance between group A and group C (P>0.05).After 12 months of treat-ment,the success rate of group A was 76.92%,the success rate of group B was 65.14%and that of group C was 94.76%. The order of the success rate from high to low was group C > group A > group B,but the success rate in group C was significantly higher than that of group A and B (P<0.05). Conclusion For the patients with geriatric root caries,the short-term and long-term effect of composite resin and glass ion sandwich restoration is perfect.This method is worthy of clinical application.
