Objective To observe the clinical effect of 3M vitremer TM in treating wedge-shaped defect. Method 300 teeth from the 128 patients with wedge-shaped defect were divided randomly into two groups：3M vitremer TM group and light-cured composite resin. Then 150 teeth were treated with 3M vitremer TM and the other 150 teeth were treated with light-cured composite resin. Follow-up examina- tions were conducted after one year. Result There were significant difference between the two groups（P 〈0.05）. Conclusion 3M glass vitremer restorative has better effect in treating wedge-shaped defect.
