正畸中釉质脱矿的控制与治疗研究进展

Research progress of the control and treatment of enamel white spot lesions in orthodontics

釉质白色损害即釉质脱矿白斑是固定正畸治疗过程中常见的并发症,发病率在50%~80%之间。早期龋损严重影响牙齿的健康与美观。因此临床上对正畸脱矿白斑的防治提倡早预防、早发现、早治疗。目前,针对正畸脱矿白斑的防治包括清除菌斑、抗菌性粘接剂的使用、局部应用防龋药物、渗透树脂治疗等。研究表明,联合应用多种措施可达到更好的控制菌斑、终止脱矿、促进釉质再矿化的效果。本文将对正畸脱矿白斑的预防、治疗等方面的新进展作一综述,为正畸临床工作提供参考。

The formation of enamel white spot lesions(WSLs)is the most common complication of fixed orthodontic treatment,whose prevalence has been reported to be 50%~80%.As an early caries defect,it severely affects the integrity and aesthetics of the teeth.So the early prevention,diagnosis and treatment are very important in preventing WSLs.There are some methods for the treatment of WSLs including plaque removal,usage of antibacterial adhesives,topical application of fluoride and resin infiltration.Studies have shown that the combination of multiple measures can achieve better control of plaque,termination of demineralization,and promotion of enamel remineralization.The purpose of this article is to review the current researches on the prevention and treatment of WSLs,and to provide clinical recommendations for both the orthodontists and the general dentists.
