    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 cone beam computed tomography voxel size and dental specialty status on the agreement of observers in the detection and measurement of periapical lesions
    (2021) Kamburoglu, Kivanc; Koc, Emre; Sonmez, Gul; Elbahary, Shlomo; Rosen, Eyal; Tsesis, Igor; 34120879
    Objective. To compare observer agreement between endodontists and oral and maxillofacial radiologists (OMRs) in the detection and measurement of periapical lesions as depicted in cone beam computed tomography (CBCT) with 2 voxel sizes. Study Design. In total, 256 CBCT images of maxillary molars were evaluated by 2 endodontists and 2 OMRs. Images were obtained at voxel sizes of 0.2 and 0.4 mm. Observers evaluated 64 endodontically and 64 nonendodontically treated teeth for the presence of periapical lesions using a 5-point confidence scale. Weighted k values were calculated to determine intra- and interobserver agreement. Intraclass correlation coefficients (ICCs) were calculated to assess intra- and interobserver agreement in width and height measurements of the lesions. Results. Intraobserver agreement ranged from fair to almost perfect, with k values higher for the OMRs than for the endodontists. Interobserver agreement between endodontists ranged from fair to moderate at the 0.2mm voxel size and was slight at 0.4 mm. Agreement between OMRs was almost perfect at 0.2 mm and ranged from substantial to almost perfect at 0.4 mm. ICC was excellent for all observers in all conditions. Conclusions. Intra- and interobserver reliability was affected by voxel size and specialty. Correlation for measurements exhibited no variation.
