Item 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, KivancBackground/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.Item Characterizing The Unseen: Clinical And Radiographic Perspectives On Unilateral Condylar Hyperplasia(JOURNAL OF STOMATOLOGY ORAL AND MAXILLOFACIAL SURGERY, 2024-12) Ergezen, Ezgi; Salyut, Ardakgul; Akdeniz, Sidika Sinem; Cubuk, SecilObjectives: Unilateral condylar hyperplasia (UCH), marked by progressive condylar growth, occurs between ages 11-30 with unclear etiology. This retrospective study aims to clarify the clinical, radiographic, and demographic features of UCH to improve its diagnosis and treatment. Material and methods: Data for all patients included in this study were retrieved from the archive. Inclusion criteria were the diagnosis of UCH supported by a positive bone scan above 10% of condylar uptake in SPECT/ CT, the patient's history of progressive facial asymmetry, symptoms confirmed by the orthodontist during follow-up, and clinical and radiological evaluation. Demographic characteristics, along with volumetric and linear measurements, were statistically evaluated. Results: Forty-one patients were included in this study with 70.73% female predominance. Patients were classified as transverse and vertical type condylar hyperplasia (CH) according to their prominent asymmetry characteristics. Eighteen patients were classified as vertical type CH and 23 patients were classified as transverse type CH. Twenty had left-side condylar overgrowth, and 21 had right-side overgrowth. Condylar volume difference was significantly higher in vertical type CH patients compared to transverse type CH (p = 0.004). No correlation was found between growth rate (bone scan uptake ratio) and condylar volume difference in patients with vertical type and transverse type CH patients (p = 0.205). Conclusion: Particularly in cases that exhibit a pronounced vertical growth tendency, volumetric and linear measurements can guide the timing and treatment planning process.

Accuracy was evaluated using the difference between planned and executed IPR. Anxiety and discomfort levels experienced by the patients were evaluated using a questionnaire of 17 questions.ResultsThe accuracy of IPR was high in groups 2 and 3; however, it was low in group 1 with the executed IPR significantly less than the planned amount. On quadrant-level, executed IPR was significantly less in the upper left quadrant in group 1, and significantly more in the upper right quadrant in group 2. The difference between planned IPR and executed IPR was significant for teeth 11, 21, 32, 33, and 43 in group 1, indicating deficiency. The average difference between planned IPR and executed IPR was 0.08 mm for group 1, 0.09 mm for group 2, and 0.1 mm for group 3. Anxiety and discomfort levels did not differ between the methods, but a negative correlation was observed between age and discomfort and anxiety levels.ConclusionsThe overall accuracy of the 2 motor-driven IPR methods was found to be better than the hand-operated system. Maxillary central incisors and mandibular canines were more prone to IPR deficiency when hand-operated abrasive strips were utilized. Patients were similarly comfortable with all 3 methods, and discomfort and anxiety levels decreased with age.Clinical relevanceMotor-driven methods have proven to be more effective when compared to the hand-operated ones by means of precision, speed, and patient comfort. If the clinician favors a hand-operated method, it may be advised to perform slightly more IPR especially on mandibular canines and maxillary central incisors.
