Investigation on physiological and clinical effects of different light sources in TMJ Photobiomodulation therapy

摘要

Introduction Laser light Electromagnetic energy has some typical properties for discussions on laser irradiation abilities to control the acute and chronic disorders in TMJ. Material and Methods During the last six years we have been completed well controlled clinical trials based on the criteria of the American Academy of orofacial pain. The study over the 600 patients (300 women and 300 men), mean age of 47 years have been developed. Patients have been selected on the main clinical sign of TMJ pain and have been divided into four main groups according to the type of PDT method. Based on the action spectra, various wavelengths have been used for TMJ Photodynamic Therapy. Constant dose and time of exposition, as well as various range of frequencies have been applied. In this way the Laser biostimulation response has been directly proportional to the total energy dose, depending of light intensity. Physiological and clinical effects of the followed "active regions"- 660 - 680, 760 - 780, 810-830 and 904 - 987 nm have been valued by method of comparative analysis. Methods applied: LLLT - TENS - red surface laser acupuncture (LA), PIPBM - LA, Laser bioenergetics approach, Complex therapeutic program (CTP). Results evaluation will be demonstrated by comparative digital ortopantomograph analysis, EEG brain maps, VAS, a metric analysis of the level of the maximum active Mandible opening and EPST through electrophysiological signal evaluation of the patient's body.
