“…The incidence of TMJ hypermobility has been reported to be greater in women [4], but this has not been substantiated by this study. The incidence of craniofacial pain conditions is also greater in women [15,19].…”

“…TMJ hypermobility was diagnosed and defined as when the "TMJ condyle overrides joint tubercle making the dull click typical of subluxation" (23.4% were so defined), while GJH was determined by the Carter-Wilkinson test as modified by Beighton [4]. It was concluded that those subjects with TMJ disorders and TMJ hypermobility both had a higher probability of GJH.…”

Generalized joint hypermobility and Temporomandibular joints disorders are more common in women. Computerized electronic 3D axiography has been used to determine whether age and gender are factors in condylar movement in an asymptomatic adolescent sample.Purpose: The present study assesses the influence of age and gender on temporomandibular joint movement.Patients and methods: A total of 63 subjects had their right and left temporomandibular joint movements recorded by 3D electronic axiography. The sample was comprised of two groups: group 11.5-13.5 (23F, 7M) and group 13.5-15.5 (17F, 12M).All subjects were asymptomatic for temporomandibular joint disorders.Results: In the determination of whether there was a gender-related difference between the key variables, one variable (Quantity -right mediotrusion) was significantly different (p > 0.001).Whether there was an age difference relationship between placement in the 11.5-13.5 or the 13.5-15.5 group, the 11.5-13.5 group had variables with significant differences (p > 0.001). These were: left start/end on open/close, DY on protrusion/retrusion, left mediotrusion -left incursive pathway, right quantity -mediotrusion-left, right start/end difference -mediotrusion-left, and left quantity -mediotrusion right.When it was determined whether males have different measurements depending whether they were in the 11.5-13.5 group. There were significant (p > 0.001) differences for right incursive coefficient -open/close, DY -open/close, and DY protrusion-retrusion (13.5-15.5 group had greater variation), while for right start/end difference protrusion-retrusion, and right quantity -mediotrusion-left (11.5-13.5 group had greater variation).For the between group comparison for females, only left quantity -mediotrusion right differed significantly, with the 11.5-13.5 group demonstrating greater variation. Conclusions:Other than for one measurement (Quantity -right -mediotrusion right) there was no difference in TMJ movement based on gender. There were significant age-related differences with both younger males and to a lesser degree females demonstrating greater variation in TMJ movements than their older cohort.

“…Meanwhile there is a stabilizing force produced by the masseter and temporalis, which with a steeper eminence, places a greater relative distalizing force relative to the disc (Atkinson & Bates, 1983;Isberg & Westesson, 1998). This might result in laxity of the ligaments that attach the disc to the condyle (Perrini et al, 1997;Deodato et al, 2006). The disc articulating against a steep eminence during mouth opening would gradually achieve a more anterior position relative to the condyle, predisposing the disc to anterior displacement (Isberg & Westesson).…”

SUMMARY: Articular eminence morphology and inclination are reported to be two predisposing factors for the internal derangement (ID). The purpose of this study is to investigate the relationship between the inclination and morphology of the articular eminence and ID. The study included 70 temporomandibular joints with ID in 35 patients: 51 joints had disc displacements with reduction (DDWR) and 19 joints had disc displacements without reduction (DDWOR). All subjects underwent bilateral high resolution magnetic resonance imaging scans which were performed in the sagittal and coronal planes with mouths closed and opened. Articular eminence morphology was characterized as box, sigmoid, flattened, or deformed. Articular eminence inclination was measured at three positions: steep (from 60° to 90°), moderate (from 30° to 60°) and shallow (from 15° to 30°). The images were divided into two; DDWR and DDWOR, and these two criteria were compared. The images of the two groups were compared; while flattened form was occurred with the highest incidence in the DDWOR group, sigmoid form was the most frequent in the DDWR group and articular eminence inclination was found steeper than it was for the DDWOR group. The steepness of the articular eminence may not have a predisposing effect on the development of disc displacements.

“…The GJH was assessed by the Carter and Wilkinson's criteria, modified by Beighton 29 , which have been used in numerous studies 4,6,[11][12][13][14][15][16] about hypermobility. Beighton's score assesses 9 joints by means of 5 tests: passive thumb opposition to the anterior portion of the forearm, until they touch; passive dorsiflexion of the little finger until it comes parallel to the forearm; elbow and knee hyperextension higher than 10 degrees; trunk flexion with the knees completely extended, in such a way that the palms of the hands touch the floor (Figure 1).…”

“…There are reports that this syndrome is more prevalent in women and in individuals of Asian and African descent, and it reduces with aging 8,9 . GJH has been associated with the development of signs and symptoms of TMD [4][5][6][10][11][12][13][14][15][16] . It is known that although the TMJ is among hypermobile joints, it may predispose some patients to subluxation, although not necessarily with pain or dysfunction 4 .…”

General ized joint hypermobility (GJH) has been considered a predisposing factor for the development of temporomandibular disorder (TMD). Aim:To evaluate clinical and psychosocial aspects in individuals diagnosed with TMD with or without GJH. Materials and methods:Clinical and experimental study, which enrolled 34 women, from 18 to 35 years of age with TMD diagnosed by RDC/TMD. The GJH was assessed by the Beighton score and volunteers were broken down into 2 groups: with GJH (n = 22) and without GJH (n = 12). Results:We found a high percentage of GJH (64.71%). All participants had myofascial pain; 79.41% had arthralgia and 41% had disk displacement. There was a correlation between higher GJH scores and higher passive mouth opening amplitude (p=0.0034), with pain (p=0.0029) and without pain (p=0.0081). Greater mandibular range of motion was observed in the group with GJH, except for protrusion. Painful mouth opening was statistically higher in the GJH group (p=0.0279).Conclusions: Individuals with TMD associated or not to GJH do not differ significantly regarding clinical and psychosocial aspects, except in the mandibular opening range of motion, which if kept at physiological levels can lead to a late diagnosis of TMD in these individuals.
