Influence of Myofascial Pain Disorder on Mandibular Border Movements and Bennett Angle Values

Myofascial pain was the most common cause of oro-facial chronic pains. It was also the leads cause of the patient to a dentist due to some other problems than toothache. Myofascial pain was the most common form of mandibular joint disorders. The Jaw movement measurements combined with clinical examination of the masticatory system could be utilize in the diagnosis of different tempromandibular joint disorders. Twenty patients with myofascial pain examined according to Research Diagnostic Criteria for Temporomandibular Disorders and twenty-control group. Cadiax compact used to evaluate Bennett angle value. The result showed lower mean value of boarder movement and Bennett angle for myofascial group compared with control with significant difference between the two groups.
