Mr. Abu Jad : A male aged 45-year old, smoker, he works a taxi driver, presented with the chief complaint of pain in the anterior of his right ear and in the zygoma. Medical history: He has CHD and takes Aspirin, Hypoprusre(Beta blocker, Metoprolol), and plavex( Clopidogrel). 3 months ago he went to Dentist with an acute pain in this region and the dentist extracted 18 & 48 but he mentioned that he had a severe pain during anesthesia. Now he suffers from a difficulty in mouth opening in the early morning and the pain in the same region.

A female aged 55-year old, nonsmoker, presented with the chief complaint of a headache & pain in the posterior of her left ear and sometimes in the chin. Medical history: She has osteoarthritis in her knees joints and takes Indomethacin. 6 months ago she went to the hospital and the neurologist refers her to the dentist. Now she suffers from the pain in the same region.

Examination with tissue-specific stress
describes the direction of any load that is responsible for an area of tissue damage within the joint and provides a better understanding of malfunctions of the system. A determination of the specific loading vector is important if one is to follow an effective procedure for arriving at a diagnosis and treatment plan.

Isometric contraction of the elevator (jaw- closing) muscles.The duration of the contraction should be between 20 and 80 seconds.According to EMG studies, correct positioning of cotton rolls between the second premolars and first molars results in maximal loading of the elevator muscles.

Monitoring contraction of the medial pterygoid muscles: Testing for
contraction of the medial pterygoid muscles. Following the contraction the patient is asked if, and exactly where, any pain was felt. The examiner must also ask if the pain is similar to that
reported in the patient history or if it is an unfamiliar pain was evoked only by the
examination.

Specific palpation is usually accomplished by laying the palpating finger parallel with the muscle fibers to be tested. The actual palpating movements then take place at right angles to the direction of the fibers. In this way even lesions in different layers of a muscle, such as the pars profunda and pars superficialis of the masseter, can be reliably differentiated (Goulet et al. 1998). A force of approximately 40 N/cm2 should be used during specific palpation. This procedure results in greater discrimination than do a number of quantitative methods for detecting painful areas (Wolfe et al. 1990).
