Abstract：Objective:To compare the clinical effect of the wedge-shaped defect with pulp exposure restored by strengthened filling method by glass fiber post and the simple filling method.Method:A total of 48 premolar teeth with wedge-shaped defect with pulp exposure from 41 women were examined. After perfect root canal therapy, 24 of them were restored by strengthened filling method, and 24 of them were restored by simple filling method. The clinical effect was evaluated 2 years after the prostheses rehabilitation. The success rate of restoration were compared usingχ2 Test, and the statistical significance (α=0.05) of the results was determined. Statistical analysis was performed with SPSS 18.0 software package.Results:In strengthened filling group, no tooth fracture occured, and two secondary caries were recorded; while in simple filling group, three restorations fell out, one secondary caries and four fractures occured. The difference was statistically significant (P<0.05).Conclusion:The strengthened filling method can protect the wedge-shaped defect with pulp exposure after root canal therapy more effectively than the simple filling method.
