title: [The comparision of clinical effects between Dyract complex and glass ionomer cement(GIC) treatment of wedge-shaped defect]
abstract: OBJECTIVE:To evaluate the curative effects of Dyract and Glass ionomer cement treating wedge-shaped defects.METHODS:92 patients with 312 teeth wedge  shaped defects were filled with Dyract and 145 patients with 346 teeth were filled with glass ionomer cement(GIC).The curative effect as to the shape,adaptation,edge coloring,tint,secondary caries,pulp electrical test and gingivitis were observed regularly for 2 years. RESULTS:There was no difference between two groups in half a year (P>0.05),but it showed significant difference after one year (P<0.05)and highly dramatic difference after two years ( P<0.005). The curative effect of Dyract was obviously better than that of GIC in shape,tint,adaptation,secondary caries and gingivitis.CONCLUSION:The long-term curative effect of Dyract was better than that of GIC.
