Condylar distances in hypermobile temporomandibular joints of @entity1 with XXXX by using computed tomography.

@entity1 @entity1348 @entity3137 @entity8018
OBJECTIVES: @entity8018 in @entity1348 ( @entity1348 ) can manifest higher range of motions in mandible. The aim of this study was to compare the position and distances of the head of condyle to glenoid fossa in TMJs of healthy individuals and @entity1 with mild, moderate and severe @entity1348 @entity8018 . MATERIAL AND METHODS: In this clinical study, 69 @entity1 (between the ages of 22 to 42) with manifestation of joint @entity8018 were included and Computed tomography were administered for both TMJs. The @entity1 were divided into three groups based on their maximum mouth opening (MMO): (A) with MMO of 50-55 mm; (B) with MMO between 55 to 65 mm; and (C) with MMO >65 mm. Also, 15 healthy @entity1 with profiled tomography in the last 6 months were assumed as control group (N) with normal MMO (<50 mm). The position of condyle from articular eminence while MMO; and the distances from anterior, superior and posterior border of condyle and facing wall of glenoid fossa were measured in closed mouth from the tomography of all contributors. The collected data were analyzed by one-way ANOVA, Post Hoc and Chi-Square tests using SPSS software version 15 at significant level of 0.05. RESULTS: The superior and posterior distances were significantly higher in groups A, B and C than healthy individuals (all P values<0.01). The anterior distance was significant between groups B and N only in right @entity1348 (P=0.013). CONCLUSIONS: @entity1348 @entity8018 showed the characteristic of increased condylar distance in posterior and superior specially in higher @entity3137 . Key words:Computed tomography, joint @entity8018 , mandibular condyle, mouth opening.
