Abstract: 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, it severely effects the integrity and aesthetics of the teeth. So, the early diagnose and treatment is 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 provides clinical recommendations for both the orthodontist and the general dentist.
