Aim: To compare the effect of Low-Level Laser Therapy (LLLT) versus Pulsed Electromagnetic Field (PEMF) on intensity of pain and on increasing maximum mouth opening on temporomandibular joint after maxillofacial surgeries. Design: Prospective single blinded pretest-post test controlled randomized trial. Patients and Methods: The present work was conducted on sixty patients (20 males and 40 females) and suffered from pain as well as decrease maximum mouth opening after 6 weeks of maxillofacial surgeries and their age range was between 18 to 42 years old. The participants selected from Outpatient Oro and Maxillofacial surgeries department of Shebin Elkom Hospital for Specialized Surgeries, and were randomly divided into two equally sized groups, each consisting of thirty patients. Group (A): (Low-Level Laser group), received treatment using infrared diode laser with a wavelength of 810 NM to 940 NM, power output of 25 MW), The laser was applied to the both side of the face to 2 points st6 and st7 for 40 second each point for 3 sessions per week for 4 weeks. In addition, NSAID twice a day for 4 weeks. Group (B): (Pulsed Electromagnetic Field group) received pulsed electromagnetic field treatment with parameters included, power 60 gauss and frequency from 50 HZ) on both side of the face for 15 min 3 sessions per week for 4 weeks in addition, NSAID twice a day for 4 weeks, the pain measured by Visual Analogue Scale before and after treatment and the maximum mouth opening measured by Digital Vernier Caliper before and after 4 weeks of treatment.
