Abstract
Objective:To compare the clinical efficacy of glass sonomer cement, light-cured composite resin and flowable resin in the dental repair of wedge-shaped defect.Method:90 patients with wedge-shaped defect in our dental clinic were selected from January 2010 to May 2014 and they were randomly divided into three groups, 30 cases in each group. Group A was given glass sonomer cement, group B adopted light-cured composite resin and group C was given the flowable resin. After 1 year of follow-up visits, the success rate of dental repair, loss rate of materials, incidence rate of irritation symptom of dental pulp and incidence rate of secondary caries of three groups were compared.Result: In 1 year, group A had 6 cases with loss of materials,group B had 4 cases and group C had 1 case,the loss rate of materials of group A was significantly higher than that of group C, the difference was statistically significant(P<0.05).Compared group A and B, the difference was not statistically significant(P>0.05).The incidence rate of irritation symptom of dental pulp of three groups was respectively 10.0%,40.0% and 3.3%,compared group A and C, the difference was not statistically significant(P>0.05)The rate of Group B was significantly higher than that of Group A and Group B, the difference was statistically significant(P<0.05).The incidence rate of secondary caries of group A and B was respectively 13.3% and 16.7%,Group C had no secondary caries,the rate of group A and B was significantly higher than that of group C, the difference was statistically significant(P<0.05).The success rate of dental repair of three groups was respectively 63.3%, 23.3% and 86.7%,the rate of group C was significantly higher than that of group A and B, the difference was statistically significant (P<0.05). After 1 week repaired, the periodontal index of three groups were significantly increased,but compared three groups the differences were not statistically significant (P>0.05).Compared 3 months and 1 weeks after repair, the periodontal index of group B and group C were significantly reduced, the differences were statistically significant (P<0.05).Compared 6 months and 3 months after repair, the periodontal index of the three groups increased, while the group A increased fastest, the difference was statistically significant(P<0.05),the other two groups were not significantly increased,the difference was not statistically significant(P>0.05).Conclusion:The flowable resin is featured as great adhesion, less irritation, ability of filling in the tooth edge, reduction of permeability and fewer damages for periodontal tissues. It has a high success rate of dental repair. It can be promoted and applied in clinical treatment.关键词
