目的：比较在相同培养条件下，变形链球菌在5种临床常用合金材料（镍铬合金、钴铬合金、金钯合金、74％金合金、86％金合金）表面的黏附情况。方法将5种合金、材料的试件（各5个）逐级打磨、抛光至粗糙度无差异，灭菌后分别置于含有变形链球菌的培养基内厌氧培养，48 h 后检测试件表面菌落生长数量。结果合金材料表面黏附的变形链球菌量：镍铬合金＞钴铬合金＞金钯合金＞74％金合金＞86％金合金。74％金合金组与86％金合金组间变形链球菌量差异无统计学意义（P ＞0．05），其余各组间差异均有统计学意义（P ＜0．05）。结论贵金属修复体在控制变形链球菌黏附方面优于普通合金修复体，临床上可考虑尽量选用贵金属材料进行修复。
目的：比較在相同培養條件下，變形鏈毬菌在5種臨床常用閤金材料（鎳鉻閤金、鈷鉻閤金、金鈀閤金、74％金閤金、86％金閤金）錶麵的黏附情況。方法將5種閤金、材料的試件（各5箇）逐級打磨、拋光至粗糙度無差異，滅菌後分彆置于含有變形鏈毬菌的培養基內厭氧培養，48 h 後檢測試件錶麵菌落生長數量。結果閤金材料錶麵黏附的變形鏈毬菌量：鎳鉻閤金＞鈷鉻閤金＞金鈀閤金＞74％金閤金＞86％金閤金。74％金閤金組與86％金閤金組間變形鏈毬菌量差異無統計學意義（P ＞0．05），其餘各組間差異均有統計學意義（P ＜0．05）。結論貴金屬脩複體在控製變形鏈毬菌黏附方麵優于普通閤金脩複體，臨床上可攷慮儘量選用貴金屬材料進行脩複。

Objective To compare the adhesion of Streptococcus mutans to surfaces of 5 differ-ent alloy materials(Ni-Cr alloy,Co-Cr alloy,Au-Pd alloy,74% Au alloy and 86% Au alloy). Methods The specimens were grinded and polished progressively until there were no significant differences in the surface roughness among the 5 alloy materials.After sterilization,the specimens were placed into the medium containing Streptococcus mutans(UA159)under anaerobic condi-tions.The number of colonies on surfaces of the specimens was counted after 48 hours.Results The number of Streptococcus mutans adhered to alloy surfaces was in the order of Ni-Cr alloy>Co-Cr alloy>Au-Pd alloy>74%Au alloy>86% Au alloy.The on difference was significant be-tween 74% Au alloy and 86% Au alloy(P >0.05).However,there were significant differences a-mong Ni-Cr alloy,Co-Cr alloy and Au-Pd alloy(P <0.05).Conclusion Precious metal prosthesis is superior to ordinary alloy prosthesis for controlling the adhesion of Streptococcus mutans. Therefore,precious metal prosthesis should be chosen as far as possible in clinical repair.
