氟漆对正畸后白垩斑的预防作用研究

The comparative study on the fluorine paint and resin permeability in the preventive effect of chalk spots after orthodontic treatment

目的:研究氟漆对正畸后白垩斑的预防作用,为临床提供参考。方法:选取我中心2015年1月~2015年12月接受正畸治疗者68例,分为两组:氟漆组34例正畸后采用氟漆预防白垩斑,对照组34例不加预防白垩斑。正畸前、6个月后分别采用分光光度计比色仪测色,记录L*a*b*值,计算前后色差值(△E)。结果:氟漆组与对照组正畸前、后6个月牙齿各部平均色差值均小于1.7的可辨色差值,但对照组体部、颈部、切端平均色差值明显高于氟漆组,差异均有统计学意义(P<0.05)。氟漆组未出现明显不良反应。结论:氟漆可有效预防正畸后白垩斑,而且操作简便,不依赖患者配合程度,便于临床推广应用。

Objective：To compare the fluorine paint and resin permeability in chalk spots after orthodontic treatment.Methods：Sixty-eight cases from January 2015 to December 2015 who used the orthodontic treatment were selected,were used by the digital table randomly to divide into two groups.The treatment with fluorine paint group were 34 cases,and resin permeability group of 34 patients with resin treatment.Before and 6 months after orthodontic treatment,the degree of spot improvement were compared between the two groups after orthodontic chalk.Results：After six months,the value of chromatism in orthodontic chalk spot in resin group were higher than in the fluorine paint group,with statistically significant differences（P〈0.05）.Conclusion：Fluorine paint can promote orthodontic early cretaceous spot mineralization,but shortterm therapeutic effect than resin permeability.
