    An Evaluation of the Relationship Between the Mesiobuccal Canal Configuration, the Interorifice Distance, and the Root Lengths of the Permanent Maxillary First Molars with Cone Beam Computed Tomography
    (DIAGNOSTICS, 2024-12) Ozemre, Mehmet Ozgur; Karslioglu, Hazal; Kamburoglu, Kivanc
    Background/Objectives: This study aimed to investigate the relationship between the mesiobuccal root canal configuration (MB RCC), the interorifice distance (IOD) and the corresponding root and other root lengths of the permanent maxillary first molars; Methods: Cone beam computed tomography (CBCT) images were acquired between 2020 and 2023 for different purposes unrelated to this study. Overall, 1550 CBCT images were retrospectively evaluated. A dentomaxillofacial radiologist with 15 years of experience evaluated the CBCT images and performed the measurements; Results: According to the MB RCC, there was no statistically significant difference between the Vertucci type II and Vertucci type IV groups in terms of the mean age and sex distribution (p = 0.694 and p = 0.273). There was no statistically significant difference in the IOD between the MB RCC groups (p = 0.755). Moreover, according to the MB RCC, there was no statistically significant difference between the Vertucci type II and Vertucci type IV groups in terms of the mesiobuccal, distobuccal, palatinal, and mean root lengths (p > 0.05); Conclusions: There was no association between the IOD and the type of RCC in the maxillary first molars. New studies conducted by collecting data from different centers to explore the different morphological features of maxillary first molars and detect their anatomical differences will provide more reliable and accurate results.

    Effect of the COVID-19 Pandemic on Anxiety in Patients with Masticatory Muscle Pain
    (2023) Arifagaoglu, Ozge; Secgin, Cansu Koseoglu; Yuzugullu, Bulem; 0000-0001-9816-2486; 34702584; GRR-7726-2022
    Statement of problem. Although psychological disorders have been established as one of the etiological factors for temporomandibular disorders, anxiety levels in individuals with masticatory muscle pain before and during the coronavirus 2019 (COVID-19) pandemic have not previously been compared.Purpose. The purpose of this clinical study was to evaluate anxiety levels in patients with masticatory muscle pain at times before and during the COVID-19 pandemic.Material and methods. Eighty patients (18 to 68 years) with masticatory muscle pain were included in the study. All participants had completed the Generalized Anxiety Disorder 7 questionnaire (GAD-7) before the first COVID-19 infection had been reported in Turkey. After the onset of the COVID-19 pandemic, all participants were contacted by telephone to repeat the GAD-7 to evaluate changes in their psychology during the first lockdown. However, 18 of the 80 patients were unreachable. A statistical analysis was performed by using the Mann-Whitney U test. Proportion comparisons between sociodemographic characteristics and GAD-7 levels were performed by using the Fisher exact test (a=.05).Results. Forty-eight (60%) of the study population were women, and 32 (40%) were men, with a mean age & PLUSMN;standard deviation of 36.63 & PLUSMN;13.85 years. Both before and during the pandemic, GAD-7 scores were statistically similar as was each demographic parameter, including sex, educational status, and occupational status (P>.05). Also, no significant correlation was recorded between age and GAD-7 global scores obtained before and during the pandemic (r=-0.098 and r=-0.052, respectively, P>.05). However, during-pandemic GAD-7 scores were statistically higher than before-pandemic GAD-7 scores (P<.001).Conclusions. Demographic parameters had no connection with anxiety levels in patients with masticatory muscle pain before and during the COVID-19 pandemic. However, the COVID-19 pandemic anxiety levels in the participants were higher than the levels before the pandemic. (J Prosthet Dent 2023;130:74-9)
