“…It has been suggested that in the absence of any disc displacements in subjects with positive RDC/TMD signs, abnormal condylar morphology might be suspected. 30 We found a higher asymmetry index of the distance from AGo to the vertical plane in subjects with unilateral TMD than those with bilateral or no TMD. Unlike our results, Trpkova et al 31 found a significantly increased asymmetry of the vertical position of AGo in bilateral TMD when exploring the asymmetry in young female patients aged between 10 and 17 years.…”

Objectives: The aim of the study was to establish the changes in posteroanterior cephalometric variables in subjects with temporomandibular joint disorders (TMDs). Methods: Posteroanterior cephalograms of 61 subjects (age range 16-36.6 years, standard deviation 4.88 years) were used to determine cephalometric differences. Subjects were classified according to the Research Diagnostic Criteria for Temporomandibular Joint Disorders into three groups: unilateral TMD, bilateral TMD and no TMD. 14 linear and angular measurements were assessed on the posteroanterior cephalogram. For assessing facial asymmetry, the asymmetry index for bilateral measurements was calculated between the right and the left side. In cases with unilateral TMD, the asymmetry index was calculated using the difference between the unaffected and affected side. The differences among multiple groups were analysed using the one-way analysis of variance test and Scheffé post hoc test. Results: 47 subjects were females (77%) and 14 were males (23%). 19 subjects had unilateral TMDs and 16 subjects had bilateral TMDs. The asymmetry index of the distance from the horizontal plane to the antegonion was higher in subjects with unilateral TMD than in patients with bilateral or no TMD (p , 0.05). Also, the asymmetry index of the distances from the vertical plane to the condyle (p 5 0.05), gonion (Go) (p 5 0.0004), antegonion (p 5 0.002) and chin (Ch) (p 5 0.02) was higher in subjects with unilateral TMDs. The asymmetry index of the O point-Go-Go9 and O point-Ch-Ch9 angles differed significantly in subjects with unilateral TMDs (p , 0.05). Conclusions: Unilateral TMDs are associated with changes in posteroanterior cephalometric measurements. The assessment of posteroanterior cephalometric variables could be used as a key factor for evaluating the presence of TMDs.

“…Condylar position may also play a significant role in the etiopathogenesis of TMJ disorders [ 21 , 22 ]. A recent study conducted by Padala et al [ 23 ] evaluated the relationship between condylar position and centric occlusion-centric relation discrepancy and presence of signs and symptoms of TMD.…”

Background and aimThis review aims at presenting a current view on the most frequent factors involved in the mechanisms causing temporomandibular disorders (TMD).MethodWe conducted a critical review of the literature for the period January 2000 to December 2014 to identify factors related to TMD development and persistence.ResultsThe etiology of TMD is multidimensional: biomechanical, neuromuscular, bio-psychosocial and biological factors may contribute to the disorder. Occlusal overloading and parafunctions (bruxism) are frequently involved as biomechanical factors; increased levels of estrogen hormones are considered biological factors affecting the temporo-mandibular-joint. Among bio-psychosocial factors, stress, anxiety or depression, were frequently encountered.ConclusionsThe etiopathogenesis of this condition is poorly understood, therefore TMDs are difficult to diagnose and manage. Early and correct identification of the possible etiologic factors will enable the appropriate treatment scheme application in order to reduce or eliminate TMDs debilitating signs and symptoms.

“…On the other hand, a few studies reported BMC patients complaining of TMJ clicking, limited mouth opening, and pain 5,23,25,26. Our study showed no significant differences in the distribution of clinical symptoms between normally shaped condyles and BMC sides (p>0.05), which meant that BMC was not provoking any TMJ symptoms.…”

PurposeThis study was performed to determine the prevalence of bifid mandibular condyles (BMCs) in asymptomatic and symptomatic temporomandibular joint (TMJ) subjects with no traumatic history, and to assess their impact on clinical and radiographic manifestations of TMJ.Materials and MethodsA total of 3,046 asymptomatic and 4,378 symptomatic patients were included in the study. Cone-beam computed tomography (CBCT) images were reviewed for bifid condyles. T-tests were used to compare the frequency of BMCs when stratified by symptom, gender, and side. In BMC patients, the clinical features of pain and noise, osseous changes, and parasagittal positioning of the condyles were compared between the normally shaped condyle side and the BMC side using chi-squared tests.ResultsFifteen (0.49%) asymptomatic and 22 (0.50%) symptomatic patients were found to have BMCs. Among the bilateral cases, the number of condyles were 19 (0.31%) and 25 (0.29%), respectively. No statistically significant differences were found between asymptomatic and symptomatic patients, between female and male patients, or between the right and left sides (p>0.05). Compared with the normally shaped condyle side, the BMC side showed no statistically significant differences in the distribution of pain and noise, parasagittal condylar position, or condylar osseous changes, with the exception of osteophytes. In the symptomatic group, osteophytes were found more frequently on the normally shaped condyle side than the BMC side (p<0.05).ConclusionBMCs tended to be identified as an incidental finding. The presence of BMC would not lead to any TMJ symptoms or cause osseous changes.
