Abstract
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.关键词
