Objectives
This study aimed to determine the frequency of temporomandibular joint (TMJ) involvement in patients with rheumatoid arthritis (RA) and to find out the correlation of serological tests with clinical symptoms of TMJs in RA patients.
Patients and Methods
This cross‐sectional study was performed on 40 patients with RA classified into two groups according to their duration of the disease. Clinical examination as well as laboratory tests were done for participants.
Results
The frequency of TMJ involvement clinically was 15% in Group A and 40% in Group B. The most frequently observed clinical symptom was facial pain (25%), and the slightest symptom was clicking (2.5%) during mouth opening. There was a positive correlation between ESR, RF, CRP and anti‐CCP and clinical sign and symptoms of TMJs in RA patients. An elevated ESR, RF CRP and anti‐CCP may indicate the presence of TMJ complains in RA patients. The chronicity of RA affects the frequency of TMJ involvement clinically, patients with longer disease duration have more clinical symptoms of TMJs. An elevated level of ESR, RF, CRP and anti‐CCP predict clinical symptoms of TMJs.
Objectives: This study aimed to determine the features of temporomandibular joint involvement in rheumatoid arthritis patients and to examine the association of radiographic changes with RA duration by comparing the diagnostic efficacy of cone-beam computerized tomography to magnetic resonance imaging in identifying changes of TMJs.Methods: This case-control study was performed on 40 RA patients with 10 healthy adults (control cases). Clinical examination with CBCT and MRI as well as laboratory tests were done for participants. Independent and paired t-tests and correlation coefficient test were used for data analysis by SPSS program Results: The frequency of TMJ involvement using CBCT and MRI techniques were 82.5% and 87.5% in RA patients and were 50% and 30% in control cases. The most frequently observed clinical symptom was facial pain (25%), and the slightest symptom was clicking (2.5%) during mouth opening. The commonest change in CBCT of RA patients was condylar head erosion (67.5%), and the less common change was articular eminence erosion (7.5%). The commonest changes in MRI of RA patients were an osseous change of condylar head (80%), and the minor change was effusion (10%), while in controls were an osseous change of condylar head (30%) and condylar head flattening (10%). There was a positive correlation between ESR, RF, and Anti-CCP and osseous TMJ changes, while CRP shows a negative correlation. Conclusions: Osseous changes occur in TMJs of RA patients with no/mild symptoms, MRI can be used as efficient imaging modality for detecting changes in TMJ, and elevated ESR, RF and Anti-CCP may indicate the presence of osseous changes in RA patients.
(1) Background: Accurate diagnosis and treatment plans in orthodontics were facilitated by novel technologies. The prediction of occlusal problems is of utmost importance for clinicians. This present study aimed to find any possible correlation between unilateral and bilateral palatally impacted maxillary canine, palatal dimensions, and maxillary arch perimeter using digital measurements and determine the factors that could be used as predictors for maxillary palatal canine impaction. (2) Method: A cross-sectional study was conducted on cone-beam computed tomography images of orthodontic patients aged 15 to 25. Palatal dimensions and maxillary arch perimeter were digitally measured using Materialize Interactive Medical Image Control System. (3) Results: A significant difference was found between the case and the study groups regarding palatal depth, length, and arch perimeter, except for the palatal width. A weak correlation was reported in palatal depth and length with canine impaction, whereas the correlation was moderate concerning the arch perimeter. They can be used as predictors for palatal canine impaction. (4) Conclusion: Palatal dimensions and dental arch perimeter affect maxillary palatal canine impaction. Deficient arch perimeter, palatal depth, and length could be helpful in the prediction of maxillary palatal canine impaction.
Dental agenesis of one or more teeth is the mostly common anomaly of dental development in man (1). Various definitions are used in the literature to describe this phenomenon. Anodontia denotes complete dental agenesis. Oligodontia referred to patients with the absence of six or more teeth, apart from the third molars. Hypodontia is used to indicate the congenital absence of one to six teeth (excluding third molars) (2,3) .
