    A Bibliometric Analysis of International Publication Trends in Total Temporomandibular Joint Replacement Research (1986-2020)
    (W B Saunders Co-Elsevier Inc, 2021) Balel, Yunus; Tumer, Mehmet Kemal
    Purpose: To conduct a bibliometric analysis that systematically characterizes publications on temporo-mandibular joint temporomandibular joint replacement from 1986 to 2020. Materials and Methods: The articles were retrieved on the same day from the Web of Science Core Collection database of the Web of Science on December 31, 2020 to prevent bias due to daily database updates. Excel 2016, CiteSpace IV, and VOSviewer v1.6.16 were used for analysis. Results: A sum of 610 publications from 1986 to 2020 were analyzed. The highest number of publi-cations were identified and published in the Journal of Oral and Maxillofacial Surgery. The United States had the highest number of publications and the highest H-index. The highest co-citations were from Mercuri. Conclusions: In this study, developments, the most influential publications, journals, and countries in the field of temporomandibular joint temporomandibular joint replacement were determined based on evidence through bibliometric analysis.

    Does Temporomandibular Joint Magnetic Resonance Imaging Diagnosis Support Clinical Examination Diagnosis Following Diagnostic Criteria for Temporomandibular Disorders?
    (W B Saunders Co-Elsevier Inc, 2023) Balel, Yunus; Yildiz, Serkan; Gokce, Erkan; Tumer, Mehmet Kemal; Ege, Bilal
    Purpose: The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) has been validated as a clinical diagnostic guideline with high-sensitivity and -specificity in identifying TMDs. The purpose of this study was to evaluate the agreement between DC/TMD diagnoses and magnetic resonance imaging (MRI) diagnoses in patients with TMD. Methods: A prospective cohort study was conducted on patients with TMD. The predictor variable was the clinical diagnosis of TMD based on DC/TMD criteria. The outcome variable was the MRI diagnosis of TMD. The diagnoses used for both the predictor variable and the outcome variable were the same. They were normal, disc displacement with reduction (DDWR), DDWR with intermittent locking, disc displacement without reduction (DDWOR) with limited opening, DDWOR without limited opening, degenerative joint disease, and subluxation. Age and gender of the patients and number of joints evaluated were covariates. Each subject had clinical examination performed by two independent Oral and Maxillofacial Surgeons. All subjects had a bilateral temporomandibular joint (TMJ) MRI performed which was evaluated by a radiologist. The correlation between the clinical and MRI diagnoses was calculated using Cohen's kappa value with a P value of <.05 considered significant. Results: A total of fifty patients (100 TMJs) were enrolled with 38 females and 12 males. The mean ages were 31.92 and 31.75 years, respectively, with a total of 100 TMJs analyzed. Internal derangement was clinically identified in 76% of the joints and with MRI in 69% of joints. The Cohen's kappa value between DC/TMD and MRI diagnoses was found to be kappa = 0.720 (P < .01). The respective sensitivity and specificity in determining disc position clinically for DDWR was 1 and 0.96; for DDWR with intermittent locking 0.78 and 0.91; for DDWOR with limited opening 0.9 and 0.98; for DDWOR without limited opening 1 and 0.9; for degenerative joint disease 0.63 and 0.97 and for subluxation 0.28 and 1.00. Conclusion: The DC/TMD clinical examination performed well in all types of disc displacement but is less reliable than MRI in detecting the presence of degenerative disc diseases and subluxation.

    Evaluation of prevalence of temporomandibular disorders based on DC/TMD Axis I diagnosis in Turkish population and correlation with Axis II
    (Elsevier, 2023) Yildiz, Serkan; Balel, Yunus; Tumer, Mehmet Kemal
    Purpose: The prevalence of DC / TMD diagnosis of individuals with internal derangement of TMJ who want to receive TMD treatment in a tertiary clinic in the Turkish population and comparison of the criteria applied in Axis I and Axis II. Methods: This study was carried out on 200 individuals older than 18 years of age who have internal disorder of Temporomandibular Joint (TMJ). Diagnostic Criteria for Temporomandibular Disorders (DC / TMD) Axis I and II were applied. Results: The female to male ratio of individuals with internal derangement of TMJ in the Turkish population was 3.5. The Pearson correlation coefficient between the internal derangement of the Right TMJ and the internal derangement of the Left TMJ is 0.804 and has a statistically significant relationship (p <0.05). Conclusions: For DC / TMD, a more comprehensive study is needed to compare the results found in the Turkish population with other populations. (c) 2022 Published by Elsevier Masson SAS.
