摘要
目的:比较采取口腔卫生措施前后金属烤瓷桥基牙牙周健康的变化,探讨维持基牙牙周健康的方法。方法:随机选取54例金属烤瓷桥患者,观察对比其采取口腔卫生措施前及采取口腔卫生措施3个月后基牙与同颌同名非基牙的龈沟出血指数、牙周探诊深度、附着丧失以及龈下菌斑细菌的构成比。结果:施加口腔卫生措施后,基牙各临床指标均有改善;与治疗前相比,龈下菌斑球菌、螺旋体和梭形杆菌构成比有显著差异(P<0.01),治疗前基牙各项指标均劣于非基牙,有显著差异(P<0.01),治疗后基牙与非基牙的龈沟出血指数、附着丧失以及龈下菌斑梭形杆菌的构成比无统计学意义(P>0.05),而二者牙周探诊深度和龈下菌斑球菌构成比的差别仍有显著差异(P<0.01),螺旋体构成比的差别有差异性(0.01<P<0.05)。结论:金属烤瓷桥基牙比非基牙更容易形成牙周破坏,施加口腔卫生措施可以改善基牙的牙周健康状况,但基牙的菌斑控制较非基牙困难。
Objective： T o co mpare with the abutment teeth of metal-porcelain fixed bridge on periodontal health before and after oral hygiene measure, and discover the method of maintain the periodontal health of abutment teeth. Methods： 54 patients wearing metal-porcelain fixed bridge were chosen randomly, applied oral hygiene measure for 3 month, bleeding index （BI）, probing depth （PD）, attactment loss （AL） and the constituent of subgingival flora of abutment and nonahutment teeth with the same name in the same jaw were observed before and after treatment. Results： After applied oral hygiene measure, all clinical index of abutment teeth were improved. The differences of the constituent of cocci, spirochaetes and fusobacterium in subgingival plaque of abutment teeth before and after treatment had highly statistical significant （P〈0.01）.Before oral hygiene measure was taken, all index of abutment teeth were worse than that of nonabutment teeth, the difference between abutment and nonabutment had highly statistical significance （P〈0.01）. But after treatment, the differences of BI,AL and the constituent of fusobacterium in subgingival plaque between abutment and nonabutment had no statistical significance （P〉0.05）, the difference of PD and the constituent of cocci in subgingival plaque between them had highly statistical significance （P 〈0.01）, and there was a significant difference between abutment and nonabutment on the constituent of spirochaetes （0.01 〈P〈0.05）. Conclusion： The periodontium of the abutment teeth of metal-porcelain fixed bridge are more easily to be destroyed than nonabutment teeth. Oral hygiene measure can improve the periodontal health of abutment teeth, but the plaque control on abutment teeth are more difficult than that of nonabutment teeth.
