【Abstract】 his study was undertaken to determine changes of pressure between the disc and fossa in the upper compartment of temporomandibular joint (TMJ) under various moving condi- tions. In order to obtain a referential normal range of synovial fluid pressure ,the author mea- sured 43 sides of intra-articular synovial fluid pressure in the TMJs in 22 normal adult,using Philip’s pressure measuring system. All results were treated statistically (range , -22. 3～+ 6mmHg) and (1) There were negative pressure on opening of the mouth , protrusion of the jaw movement towards the contralateral side , chewing , swallowitng,smilit.g ,speaking as well as in a steady state ,with the highest negatvie value during the chewing movement (mean,- 11. 86mmHg) , (2)There were positive pressure of the mouth on closing ,retrusion and lateral movement of the jaw to the ipsilateral side ,with the highest positive value during mouth clos- ing (mean, 2. 88 mmHg) . (3) When in the resting position, the mean TMJs pressure was -2. 87 mmHg. (4)Only during opening movement TMJ pressure were statistically different beteen male and female. (5)No different joint 0ressure between bilateral TMJs were showed.更多还原
