Abstract：AIM：To compare the clinical effects of repairing the residual roots and residual crowns of molar teeth with silver amalgam or composite resin. METHODS: 100 lower first molars with residual roots or residual crowns by caries were chosen. After root canal therapy, pin retention was adopted, 50 were repaired ones with silver amalgam and 50 ones with composite resin. Then compare their clinical effects for two years. RESULTS: The clinical effects of silver amalgam group showed 45 teeth best or better(90%), 4 teeth good(8%), 1 tooth bad(2%). The clinical effects of composite resin group showed 40 teeth best or better (80%), 6 teeth good(10%), 4 teeth bad(8%) Both successful rates were checked by χ2, P>0.05. CONCLUSION: The clinical effects of repairing residual roots and residual crowns silver amalgam or composite resin are no differece obviously.
