Background The objectives were to determine the percentage of children in Kindergarten through Grade 5 who reported TMD symptoms, to assess whether gender, race, and socioeconomic background mattered, and to explore the relationships between TMD and children’s oral health and oral health-related quality of life (OHRQoL). Methods Face-to-face interviews were conducted with 8,302 children in Kindergarten through Grade 5 (51% female/49% male; 53% African American/42% European American). Oral health screenings were conducted with 7,439 children. Results 23.6% of the children reported pain when chewing tough food and 18.8% when opening their mouth wide; 23.2% reported to hear a sound (clicking) when opening their mouth wide. Female students were more likely than male students and African American children were more likely than European American children to report TMD symptoms. The prevalence of TMD symptoms was not correlated with whether the children had a need for oral health care services, or whether they had an abscess or carious teeth with pulpal involvement. They were significantly associated with children’s OHRQoL. Conclusions Considerable percentages of 4–12 year old children reported TMD symptoms, with girls and African American children being more likely than their counterparts to be affected. Experiencing TMD symptoms is significantly associated with poorer OHRQoL. Practical Implications Dental practitioners need to be aware that substantial percentages of Kindergarten and elementary school age children experience TMD symptoms. Taking a dental history and conducting an oral exam should therefore include assessments of the signs and symptoms of TMD; treatment recommendations should be provided for affected children.

“…It was reported that osteoarthrosis was not observed in patients without ID, indicating a strong correlation between osteoarthrosis and ID 19 . Many studies suggested that there is a strong correlation between ADDWOR and osteoarthrosis, and specifically reported that pain increased significantly in patients with ADDWOR in concurrence with osteoarthrosis 3 20 21 22 23 . Nevertheless, such a correlation between osteoarthrosis and the possibility of pain remains uncertain.…”

ObjectivesThe purpose of this study was to clarify which findings in magnetic resonance imaging (MRI) are good predicators of pain and mouth opening limitation in patients with temporomandibular joint (TMJ) internal derangement (ID).Materials and MethodsClinical examinations for pain and mouth opening limitation were conducted for suspected TMJ ID. MRI scans were taken within a week of clinical examinations. On the oblique-sagittal plane image, readings were obtained in terms of the functional aspect of disc position, degree of displacement, disc deformity, joint effusion, and osteoarthrosis. Multiple logistic regression analyses were conducted to identify the predictors of pain and mouth opening limitation.ResultsA total of 48 patients (96 TMJs) were studied, including 39 female patients and 9 male patients whose ages ranged from 10 to 65 years. The resultant data showed significant correlations between pain and the MR imaging of the degree of disc displacement (P<0.05). The probability of there being pain in moderate to significant cases was 9.69 times higher than in normal cases. No significant correlation was found between mouth opening limitation and MRI findings.ConclusionWe identified a significant correlation between clinical symptoms and MRI findings of ID. The degree of anterior disc displacement may be useful for predicting pain in patients with TMJ ID.

“…17,18 MRIs have provided essential information about disk position, morphology, and integrity. 18,[20][21][22][23][24][25][26] Cone-beam computed tomography (CBCT) has assumed a prominent role in the diagnosis of condylar remodeling. 19 Computed tomography (CT) is generally accepted as the most useful technique for assessing OA changes in the TMJs, being able to provide clinicians and researchers with detailed information on bone remodeling.…”

This study aimed to investigate imaging statistical approaches for classifying three-dimensional (3-D) osteoarthritic morphological variations among 169 temporomandibular joint (TMJ) condyles. Cone-beam computed tomography scans were acquired from 69 subjects with long-term TMJ osteoarthritis (OA), 15 subjects at initial diagnosis of OA, and 7 healthy controls. Three-dimensional surface models of the condyles were constructed and SPHARM-PDM established correspondent points on each model. Multivariate analysis of covariance and direction-projection-permutation (DiProPerm) were used for testing statistical significance of the differences between the groups determined by clinical and radiographic diagnoses. Unsupervised classification using hierarchical agglomerative clustering was then conducted. Compared with healthy controls, OA average condyle was significantly smaller in all dimensions except its anterior surface. Significant flattening of the lateral pole was noticed at initial diagnosis. We observed areas of 3.88-mm bone resorption at the superior surface and 3.10-mm bone apposition at the anterior aspect of the long-term OA average model. DiProPerm supported a significant difference between the healthy control and OA group ([Formula: see text]). Clinically meaningful unsupervised classification of TMJ condylar morphology determined a preliminary diagnostic index of 3-D osteoarthritic changes, which may be the first step towards a more targeted diagnosis of this condition.
