title: Linear polarized near-infrared irradiation stimulates mechanical expansion of the rat sagittal suture.
abstract: Mechanical sutural separation has been carried out in clinical orthodontics for controlling the growth of the craniofacial skeleton. This study was designed to evaluate the effects of linear polarized near-infrared ray irradiation on the sutural expansion of rat sagittal suture. Twenty 8-week-old Wistar strain male rats were equally divided into experimental and control groups. Suture expansion was carried out for 5 days for all animals using an expansion appliance. The experimental animals were subjected to linear polarized near-infrared irradiation. This study has demonstrated that linear polarized near-infrared irradiation stimulates sutural expansion without any pathological changes.
