| Abstract: | Objective To contrast the clinical curative effect of GC Fuji IX GP with those 3M Z250 in repairing the midrange wedge-shaped defect of dental cervix. Melhods Tooth of wedge-shaped defect were randomly divided into 2 groups. Group A were repaired by GC Fuji IX GP, Group B were repaired by 3M Z250. The curative effect were reexamined after one year. Results The sueess rate of group A was 91.3% , that of group B was 81.1%. the sueess rate of group A was significant higher than that of group B. Conclusion GC Fuji IX GP is an ideal material to repair wedge-shaped defect. It possess favourable biocompatility. The coefficient of expansion due to heat is similar to odontal tissue. The block of the wedge is well. It can prevent caries through releasing fluorine. |
