Electromagnetic energy of laser light has some typical properties which are found to be a premise for discussions on laser irradiation abilities to control the severe and chronic disorders in TMJ. In world literature PDT application is recommended when soft tissues in TMJ are damaged, in cases of degenerative diseases of discus articularis, medial and lateral distensions of joint ligaments, chronic inflammatory processes in TMJ, occlusion trauma, etc. The aim of our clinical study was to analyze the theoretical achievements up to now in depth and basing on our clinic
al observations suggest new methods guaranteeing high therapeutic efficacy of Photodynamic therapy.
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.
