摘要
目的:比较使用护牙素与健齿膏预防接受牙齿固定正畸治疗的患者发生牙釉质脱矿的临床效果。方法:将2015年10月至2017年3月期间在重庆市綦江区中医院进行牙齿固定正畸治疗的60例患者作为研究对象,并将其随机平均分为甲组、乙组和丙组。为三组患者均使用含氟牙膏进行治疗。在此基础上,为乙组患者使用含CPP-ACP(酪蛋白磷酸多肽-无定形磷酸钙)的护牙素进行治疗。为丙组患者使用含生物活性玻璃的健齿膏进行治疗。然后,比较三组患者的EDI(牙釉质脱矿指数)。结果:进行牙齿固定正畸治疗前,三组患者的EDI相比,P>0.05。进行牙齿固定正畸治疗24个月末,乙组患者和丙组患者的EDI相比,P>0.05。与甲组患者相比,乙组患者和丙组患者的EDI均更低,P <0.05。结论:使用护牙素与健齿膏预防接受牙齿固定正畸治疗的患者发生牙釉质脱矿的效果均较好,用药后其EDI均可显著降低。
objective: to compare the clinical effect of tooth enamel demineralization in patients receiving fixed orthodontic treatment by using dental protectin and jianfang cream. Methods: 60 cases of patients who received orthodontic treatment of fixed teeth in qijiang district hospital of traditional Chinese medicine in chongqing from October 2015 to March 2017 were selected as the research objects, and randomly divided into group a, group b and group c on average. All three groups were treated with fluoride toothpaste. On this basis, dental protectin containing cpp-acp(casein phosphopeptide-amorphous calcium phosphate) was used to treat group b patients.Patients in group c were treated with dental cream containing bioactive glass. Then EDI(enamel demineralization index) was compared among the three groups. Results:compared with EDI before orthodontic treatment, P > was 0.05. At the end of 24 months after orthodontic treatment, EDI of group b and group c showed P > 0.05.Compared with group a, patients in group b and group c had lower EDI, P < 0.05. Conclusion: the effect of enamel demineralization in patients receiving fixed orthodontic treatment is better by using dental protectin and jianfang cream, and EDI can be significantly reduced after the treatment.
