An evaluation of root resorption associated with the use of photobiomodulation during orthodontic treatment with clear aligners: a retrospective cohort pilot study.

The article examines the effect of photobiomodulation (PBM) therapy on root resorption in orthodontic treatment with clear aligners, utilizing cone-beam computed tomography (CBCT) to analyze changes in tooth root volume. It discusses the comparison between PBM and control groups regarding orthodontically induced external root resorption, emphasizes the need for cautious interpretation due to study limitations such as sample size and measurement errors in root segmentation.
