    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.

    Comparison of periapical radiography, panoramic, and cone-beam CT in the detection of dental caries in dog teeth
    (2019) Orhan, Kaan; Ozemre, Mehmet Ozgur; Secgin, Cansu Koseoglu; Vural, Sevil Atalay; Gur, Gurkan; Kamburoglu, Kivanc
    The aim of this study was to compare the effectiveness of panoramic, periapical and two different Cone Beam Computed Tomography (CBCT) devices in the detection of dental caries of dog teeth ex vivo. A total of 880 teeth were investigated, 33 of which were with caries, whereas; 33 healthy teeth were the controls. Periapical, panoramic and CBCT scans were made for the assessment of the teeth. All images were evaluated separately by two observers experienced in image interpretation. The presence or absence of occlusal caries was scored using a 5-point scale. Kappa values were calculated to assess intra and interobserver agreement. Receiver Operating Characteristic (ROC) analysis was performed to compare the effectiveness of different imaging methods in the detection of dental caries. For both observers, the order of success of the image sets in the estimation of the caries tooth was CBCT Morita, CBCT Iluma, periapical and panoramic radiograph (Area Under Curve (AUC): 0.929, 0.882, 0.861, and 0.704 for observer 1, AUC: 0.927, 0.896, 0.875, and 0.693 for observer 2, respectively). CBCT was found to be the best imaging method for the ex vivo detection of caries in dog teeth. In addition, panoramic images performed worse than all other modalities.
