摘要: 采用实验室方法,对临床常用的不同托槽进行主要致龋菌变形链球菌(简称变链菌)附着后清除的定量对比研究,即将每种托槽分为2组放入变链菌的选择性培养基中培养48h,吸附组烘干称质量,清除组放入磁力搅拌器搅拌1min后烘干称质量,并进行清除率比较.发现金属不锈钢托槽清除率最好:进口托槽为88.29%,国产托槽为83.54%,陶瓷托槽与塑料托槽的清除率分别为80.95%与14.28%.建议口腔卫生习惯较差或好发龋病的患者使用金属不锈钢托槽.

Abstract: For the selection of orthodontic appliances in clinic and the guidance of demineralizing prevention, the streptococcus was studied in attachment and cleaning ratio and ratio from brackets. In vitro, two groups of many kinds of brackets were cultivated in streptococcus culture medium for 48 h. The brackets in attachments group were dried and weighed up and in the cleaning group were churned up in puddler and weighed up. In comparison of the two groups, result displayed that the cleaning rate of stainless steel brackets was higher(the brackets made abroad were 88.29% and those made in China were 83.54%). Ceramic brackets were 80.95% and the plastic ones were 14.28%. So the stainless steel brackets are recommended to patients whose oral hygiene is not good and who live in easy-carious areas.
