目的探究正畸治疗中预防牙釉质脱矿的有效方法。方法选取2008年3月—2013年3月广西科技大学第一附属医院收治的使用固定矫治器治疗的患者240例,入院前均无矫治病史。将患者随机分为第一组和第二组,每组120例。再将第一组前60例患者即为A组,后60例患者即为B组;第二组前60例患者即为C组,后60例患者即为D组。第一组中,A组患者刷牙使用含氟牙膏,B组患者使用普通牙膏;第二组中,C组患者使用传统直丝弓矫治器,D组患者使用自锁托槽直丝弓矫治器。分别统计每一组患者两种防治方法对于牙釉质的脱矿情况,并分析比较。结果第一组内,A、B组患者预防前的发生率比较,差异无统计学意义(P>0.05);A组患者预防后发生率低于B组,差异有统计学意义(P<0.05)。第二组内,C、D组患者预防前的发生率比较,差异无统计学意义(P>0.05);D组患者预防后发生率低于C组,差异有统计学意义(P<0.05)。结论患者在正畸治疗中可以采取以下措施预防牙釉质脱矿:使用含氟制剂,使用有更好防治作用的矫治器,二者均能有效减少患者牙釉质脱矿的发生。
Objective To explore an effective method to prevent enamel demineralization during orthodontic treatment. Methods From March 2008 to March 2013, 240 patients were treated with fixed appliance in the First Affiliated Hospital of Guangxi University of Science and Technology. There was no history of hospitalization before admission. The patients were randomly divided into the first group and the second group, 120 cases in each group. Then the first group of 60 patients is the A group, the latter 60 patients is the B group; the first group of 60 patients is the C group, the latter 60 patients is the D group. In the first group, group A patients used fluoride toothpaste to brush their teeth, while group B used ordinary toothpaste. In the second group, patients in group C used traditional straight wire appliance and group D patients used self-ligating appliance . The statistics of demineralization and enamel demineralization in two groups of patients in each group were analyzed and compared. Results There was no significant difference in the incidence of pre-prevention in group A and group B (P> 0.05). The incidence of post-prevention in group A was lower than that in group B (P <0.05) ). There was no significant difference in the incidence of pre-prevention among patients in group C and group D (P> 0.05). The incidence of post-prevention in group D was lower than that in group C (P <0.05) . Conclusion In orthodontic treatment, the following measures can be taken to prevent enamel demineralization: Fluoride-containing preparations and appliances with better prevention and treatment effects can both reduce the occurrence of enamel demineralization in patients.
