| 摘 要： | 目的 初步探讨可摘局部义齿卡环对基牙健康的影响。方法 对铸造、冷弯卡环可摘局部义齿初截一周前后，基牙菌斑中的主要致龋菌进行分析比较。结果 铸造卡环组初戴一周后，基牙菌斑中粘性放线菌与变形链球菌的百分比分别上升了２．３％和３．８％；冷弯卡环组初戴一周后，上述细菌百分比分别上升了５．９％和３．３％，二者间差异有显著性；铸造卡环组粘性放线菌上升的百分比显著低于冷弯卡环组。结论 可摘局部义齿卡环会增加基牙 |

| Abstract: | Objective The effect of clasp on the health of abutment teeth. Methods To analyse and compare the cariogenic bacteria plaque getting from the buccal cervical third of casting and wrought wire clasp teeth before and one week after wearing removable partial dentures. Results The average percentages of Streptococcus Mutans and Actinomyces Viscosus in total culturable bacteria rised significently in statistical analysis, but there was no significent difference of Lactobacilli. The average percentage of Actinomyces Viscosus increased less after wearing casting clasp RPD than that of wrought wire clasp. Conclusion Clasps of RPD increased the risk of root caries of abutment teeth. However the influence of casting clasps was smaller than that of wrought wire clasps. |
