Abstract
We thank the authors for their randomized clinical trial (Albhaisi Z, Al-Khateeb SN, Abu Alhaija ES. Enamel demineralization during clear aligner orthodontic treatment compared with fixed appliance therapy, evaluated with quantitative light-induced fluorescence: a randomized clinical trial. Am J Orthod Dentofacial Orthop 2020;157:594-601). This study was interesting and extensive, and we would like to put forward a few queries regarding the article.1.It was not described in the study whether brackets and composite resin were present or removed from the teeth to visualize white spot lesions (WSL) using quantitative light-induced fluorescence. Brackets and accessories on a tooth affect the correct estimation of fluorescence loss and area of the lesion because there is less healthy tooth tissue available to use as a reference in the assessment of WSL. The full extent of WSL developed adjacent to orthodontic brackets will only become apparent after debonding.1van der Kaaij N.C.W. Faaij M.J. Ten Cate J.M. van der Veen M.H.
