正畸牙釉质脱矿与应用3种不同牙刷的比较

背景：近年来，有大量关于防正畸牙釉质脱矿方面的研究，但目前还未有学者对普通牙刷、正畸专用牙刷及牙间刷3者做过这方面的比较研究。目的：比较分别使用普通牙刷、正畸牙刷及牙间刷对正畸牙釉质脱矿的影响。方法：将12-17岁的青少年正畸患者按使用牙刷的种类不同，随机分成普通牙刷组、正畸专用牙刷组和牙间刷组。由同一正畸专科医生检查并计算矫治前和矫治1年后釉质脱矿指数和釉质脱矿增加指数。结果与结论：正畸治疗前，3组患者的釉质脱矿指数差异无显著性意义(P > 0.05)。治疗1年后，各组患者的釉质脱矿指数均大于其矫治前(P < 0.05)。矫治1年后，3组间脱矿指数及脱矿增加指数的两两比较：正畸专用牙刷组< 普通牙刷组< 牙间刷组(P < 0.05)。结果证实，使用正畸专用牙刷对防治正畸治疗中的釉质脱矿效果更好，更适用于正畸人群；而单独使用牙间刷并不能起到很好的防止釉质脱矿的作用。中国组织工程研究杂志出版内容重点：生物材料；骨生物材料; 口腔生物材料; 纳米材料; 缓释材料; 材料相容性；组织工程全文链接：

Influence of three types of toothbrushes on enamel decalcification in orthodontic patients: a comparative study

BACKGROUND:A number of studies have been conducted on the prevention of enamel demineralization in orthodontic treatment, but no work has been carried out on the comparative studies addressing manual toothbrush, orthodontic fur V brush and interdental brush.OBJECTIVE:To compare the efficacy of manual toothbrush, orthodontic fur V brush and interdental brush on enamel decalcification during orthodontic treatment.METHODS:Adolescents, aged 12 to 17 years old, were randomly and averagely divided into three groups: manual toothbrush, orthodontic fur V brush, and interdental brush groups. Enamel decalcification index and augmenter of enamel decalcification index were examined and calculated by the same orthodontist before treatment and 1 year later.RESULTS AND CONCLUSION: There was no statistical difference in the enamel decalcification index among the three groups at the beginning (P > 0.05). After 1 year of treatment, the enamel decalcification index of each group was higher than that at the beginning (P < 0.05); the enamel decalcification index and augmenter of enamel decalcification index in the three groups were ranked as follows: orthodontic Fur V toothbrush group < manual toothbrush < interdental toothbrush group , and there was a statistical significant difference among the three groups (P < 0.05). Orthodontic fur V brush is proved to have advantages over manual toothbrush and interdental brush in the respect of controlling enamel decalcification, and interdental brush has no good effect on preventing enamel demineralization while it is used alone.
