Summary

The purpose of this study will be to evaluate the effect of laser therapy on lateral pterygoid muscle in patients with Wilke's stage I and II temporomandibular disorders (TMD).

Interventions

Type	Name	Description
PROCEDURE	laser therapy in TMD	In this study patients will receive the Low-level laser therapy with a 635 nm wavelength diode laser (Lasotronix, Diode Laser DiodeLX model SMART M; Zytnia, Piaseczno, Poland) with 200 mW in a continuous mode, using a handpiece with a cylindrical applicator with a diameter of 8 mm in contact mode extra-orally, fiber-optic applicator with a diameter of 8 mm in contact mode intraorally, with a power density of 400 mW/cm2, delivering 10-12 J/cm2 on each application point, over a period of 20 sec. There are two methods for examination of lateral pterygoid muscle: digital palpation and functional manipulation. For digital palpation of lateral pterygoid muscle, we place our index finger or tip of our little finger in the vestibular area adjacent to the maxillary third molar. Functional manipulation of the inferior head of lateral pterygoid muscle: It is best accomplished by having the patient make a protrusive movement against resistance to contract it since this muscle is the primary pro
