The aims of the study were to compare the degree of demineralization and the size alteration of white spot lesions after orthodontic treatment using fluoride dentifrice or tooth mousse therapy. Twelve upper incisors with demineralized white spot lesions of eight participants were identified after fixed appliances were removed. These participants were randomly and double blindly assigned to use one of the two dentifrices (TM and FD). Degree of demineralization was examined using DIAGNodent pen and digital photographs were taken at bracket removal, 4 weeks and 8 weeks later. Image J, one image processing software, was used to measure the size of lesions on digital photographs. The results showed that the degree of demineralization was improved after 4 weeks for both toothpastes. The mean sizes of the white spot lesions for tooth mousse group (TM) decreased from 41.07% to 24.62% after 4 weeks, and it had statistically significant difference. The mean sizes of the white spot lesions for fluoride dentifrice group (FD) decreased from 35.45% to 15.44% after 8 weeks, and it reached statistically significant difference. It was concluded that the degree of demineralization of post-orthodontic white spot lesions could be improved after 4 weeks therapy for two toothpastes. The size of the lesions reduced was earlier detected following tooth mousse treatment than fluoride dentifrice treatment.
