Effects comparison of glass ionomer and light-cured composite resin in treatment of root caries of premolars in elderly patients
Objective To compare the clinical efficacy of Fuji Ⅸ glass ionomer and light-cured composite resin in treatment of root caries of premolars in elderly patients,and explore the better filling materials. Methods One hundred and sixty premolars with root caries were selected from 143 elderly patients,and were divided into 2 groups medially.Group A was treated with Fuji Ⅸ glass ionomer,and group B was treated with light-cured composite resin. All patients were followed up 12 months after treatment. Treatment effects was evaluated according to certain standards. The results of evaluation were analyzed using Chi-square test. Results In group A,75 teeth succeeded,5 teeth failed,and the success rate was 93. 75%. In group B,67 teeth succeeded,13 teeth failed,and the success rate was 83. 75%. The success rate of group A was higher than that of Group B,and the difference was statistically significant( χ2= 4. 006,P = 0. 045).Conclusion Fuji Ⅸ glass ionomer showed better clinical efficacy than light-cured composite resin treatment of root caries of premolars in aged patients,and was more preferable.
