Abstract
Aim: To evaluate the effects of laser versus anterior repositioning splint (ARS) in the treatment of disc displacement with reduction (DDWR) on the improvement of signs and symptoms of Temporomandibular Disorders (TMD) as well as articular disc position and morphology. Methods: A total of 30 TMD patients diagnosed with DDwR according to the research diagnostic criteria of TMD (RDC/TMD) and confirmed by magnetic resonance imaging were randomly divided into 3 groups: group (1) received an anterior repositioning splint (ARS) worn at night for 3 months, group (2) received low-level laser therapy (InGaAsP Semi-conductor diode, n=940 nm, P=40 mW, CW, ED= 1.8 KJ) while group (3) received placebo laser therapy. Both laser and placebo groups received 12 laser/sham sessions over 3 months. Measurement of Pain Visual Analogue Scale, presence or absence of joint sounds, jaw opening, and disc recapture (change in the articular disc position and configuration) on MRI using a 2D imaging software, were performed before treatment (T1) and repeated after treatment (T2). Results: Despite that statistically significant improvements were found within the laser and splint groups after treatment concerning characteristic pain intensity, joint sounds, and mouth opening; no significant inter-group differences were found. MRI measurements showed improvements in the angular deviation of the articular disc within the splint and laser groups, yet on comparing the 3 groups no statistically significant differences were noted. Conclusions: Although not statistically significant, clinically beneficial effects were noted for both LLLT and ARS, Clinically beneficial results were noted which require further investigation
