RESUMO
@#Temporomandibular joint is the pivot joint system in oral and maxillofacial chewing system, bearing the intricate function such as speaking and chewing movement. During the process of derangement or functional impairment of temporomandibular joint, there are some changes in radiograph or the synovial fluid physical and chemical properties. Besides, the variation of intra-articular pressure also reflects the pathological mechanism and course of temporomandibular joint disorders. This article will review our related researches on intra-articular pressure of temporomandibular joint in the last 30 years, including the fluctuating rule, its significance of intra-articular pressure in TMJ and the effect of that on the joint physiopathology and biomechanics, to provide new ideas for clinical diagnosis and treatment of temporomandibular disorders.

RESUMO
Objective:To dynamically observe the change of intra-articular pressure of the hip by means of injecting 2‰Noradrenaline(NA)into the hip joint cavity,to study the effects of intra-articular pressure change on transient synovitis of hip(TSH).Methods:Fourty-eight dogs aged 2~3 months had been randomly divided into 12 groups,with four in each group All were injected 2‰NA into the hip joint an four assessments had been done.①The intra-articular pressure of hip was determined at different times.②99m TC-MDP triphasic imaging was used to observe the local blood supply of femoral head.③Pathological changes were observed to understand the disease course.④X-ray was adopted to exmine the hip.Result:Noradrenaline induced transient synovitis of hip,and synovitis resulted in the increase of intra-articular pressure of hip which was over 20mmHg and lowered to be normal with the inflammation fading away.Transient blood insufficiency was observed in femoral head,but with no putrescence.Conclusion:In transient synovitis of hip,synovitis resulted in the change of intra-articular pressure hip,which changed to be normal as the inflammation faded away;and the intra-articular pressure change would influence the blood supply in femoral head,and could canse transient blood insufficiency.
