Photodiagnosis of White Spot Lesions after Orthodontic Treatment with a Quantitative Light-induced Fluorescence-Digital System: A Pilot Study

Kang, Si-Mook / Jeong, Seung-Hwa / Kim, Hee-Eun / Kim, Baek-IlPage 483 - 488Purpose: To confirm that the quantitative light-induced fluorescence-digital (QLF-D) system is an adequate tool for monitoring changes in the mineral contents of white spot lesions.Materials and Methods: Twenty-three anterior teeth from five orthodontic patients were selected for the samples. Initial fluorescent images were taken with the QLF-D system immediately after removing the fixed orthodontic appliances, and the white spot lesions were visualised in the fluorescent images that were selected. Subsequently, a fluoride varnish containing 0.1% fluoride was applied to all white spot lesions, and the final QLF-D images were taken two weeks after fluoride treatment. Finally, the following four parameters were compared between the images taken at baseline and two weeks after the treatment with paired t-tests: the mean fluorescence loss ( ∆F), maximum fluorescence loss (∆Fmax), lesion area (area), and lesion volume (∆Q).Results: All the parameters obtained by QLF-D after two weeks had improved significantly when compared with baseline (p
