An interventional study of Laser and light-emitting diode (LED) in Orthodontic Pathological Resorption of External Root, Orthodontic Appliance Complication and Orthodontic Tooth Movement, sponsored by University of Gaziantep. Completed at 1 site in Turkey. Open to participants aged 15 Years to 17 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-08-05.

Objectives: The aim of this study is to investigate the effect of photobiomodulation therapies on root resorption compared with the placebo group. Materials and Methods: 30 patients, who were admitted to the ............. University Faculty of Dentistry Orthodontics Department for treatment, with an indication of upper right 1st premolar tooth extraction was included. Before the individuals' orthodontic treatment, 0.022 slot MBT brackets and tubes were placed on the maxillary 1st premolar and molar. A 150g buccal tipping force was applied to the 1st premolar. Individuals were then randomly divided into 3 groups. For the first group; laser application was performed with a 810 nm GaAlAs laser device at 0,3,7,14,21 and 28 days to 8 J/cm2. Second group; an LED application according to the manufacturer's instructions with a 850 nm wavelength and 20 mW/cm2 output power for 10 minutes per day during the experiment. Third group; a placebo therapy was completed whereby a laser device that did not make active pulses was used. At the end of four weeks, the amount of root surface resorption was compared using micro-CT imaging after the extraction of the teeth.
Exclusion Criteria:
The resorption cavities on the root surface were determined and the volumes of the cavities were measured in CTAn software (micro-CT).
