| Objective: To evaluate the effects of retention force of casting metal full crown on different luting cements.Material and methods: 90 extracted intact human pre-molar teeth were invested and prepared by lathe .The size of tooth about height is 4㎜, about perimeter is 20㎜.The casting metal full crown was made by losting wax. The casting was cemented by different luting cements. The retention fore of casting metal crown was measured and evaluated by One-way ANOVA (P<0.5).Results: Cements voried with effection on retention force of casting metal crown.Conclusion: Luting cements differed considerably with effection on retention force of casting metal crown. |
