    Comparison of condylar and ramal asymmetries in different temporomandibular joint disorders
    (2020) Polat, Mehmet Emrah; Polat, Mevlude
    Aim: The aim of this study is to compare condylar and ramal asymmetries in different temporomandibular joint disorders.Material and Methods: A total of 91 patients ranging in age from 15 to 79 were included in this study. The study groups were as follows: temporomandibular joint osteoarthritis (OA) group (N=24), disc displacement with reduction (DDWR) group (N=26), disc displacement without reduction (DDWoR) group (N=20), and control group (N=21). All patients’ vertical condylar and ramal heights were measured from panoramic radiographs, and condylar (CAI) ramal (RAI), and total (TAI; condylar + ramal) asymmetry indices were calculated according to Habets el al’s formula.Results: Statistical evaluations were made with the Kruskal–Wallis test using SPSS. Although TAI (p=0.110) and age (p = 0.610) did not differ significantly among the four groups, RAI (p=0.003) and CAI (p = 0.034) did. In intergroup estimates for RAI comparisons, significant differences were observed between the OA and DDWR groups (p=0.004, p=0.033) and between the OA and control groups (p=0.033). Evaluations of CAI among groups showed significant differences only for the OA vs. control group comparison (p=0.022). Conclusion: These results show that OA, a degenerative disease, has greater effects on vertical condylar and ramal asymmetry than on disc displacements and that there are no significant differences between the control and disc displacement groups in terms of CAI.

    Evaluation of the compatibility of clinical primary diagnoses with mri reports in patients with temporomandibular disc displacement
    (2020) Yanik, Saim; Polat, Mevlude
    Aim: Temporomandibular joint disorder (TMD) is a common disease group in the community that includes chewing muscles and temporomandibular joint (TMJ) components. TMJ diseases are also the main cause of non-odontogenic pain of the orofacial region. The aim of this study is to evaluate the consistency between clinical diagnosis and Magnetic Resonance Imaging (MRI) reports in patients with reduction with disc displacement (DDWR) and reduction without disc displacement (DDWoR).Materials and Methods: A total of 62 TMJ anamnesis records and MRI results were evaluated by authors. Radiology reports and anamnesis records were divided into two groups according to the clinical primary diagnosis file as DDWR and DDWoR. The clinical and radiographic results were compared each other and the correlation between these results was evaluated statistically.Results: The study includes sixty-two patients’ MRI reports and TMJ clinical anamnesis files (12 males and 50 female) with a mean age of 31.20±13.66 years. In group DDWoR there is only 41.9 % and in group DDWR there is only 45.2 % correlation found between clinical and MRI reports of the patients. Although the values obtained are statistically significant, there is insignificant agreement between in the TMJ clinical anamnesis file and MRI report results. There is no statistically significant difference between primary clinical diagnosis groups in terms of clinical and MRI diagnosis compatibility.Conclusion: It is concluded that clinical findings determined by the clinicians do not compatible MRI reports determined by radiologist. This may be due to the subjective nature of the clinical findings, and both MRI and clinical results are needed for precise results.
