Item Evaluation of the Appearance, Location and Morphology of Lingual Foramens in Dentates and Edentulous Mandibles Using CBCT(2022) Citir, Mesude; Karslioglu, Hazal; Sumer, Ayse Pinar; Kasap, PelinObjective: The lingual foramen (LF) in the anterior mandibular region is important for surgical planning. Our aim was to assess the anatomical variations of the mandibular LF and canals using cone beam computed tomography (CBCT). Materials and Methods: CBCT images of 148 patients were evaluated. The LF presence, number, position, diameter and trajectory was established. The relationship between the findings and gender, dental status was evaluated using Mann-Whitney U, independent samples t-test, and Spearman correlation. Results: Of 102 patients, 5.9% had the inferior foramen, 60.8% had the superior foramen, and 33.3% had two foramina. The average diameter of the inferior LF was 1.08 mm and superior LF was 1.21 mm. There is a statistical difference between genders according to the diameter of the inferior LF (p=0.031). Conclusion: Due to the prevalence of foramines of different sizes and locations, we recommend assessing with CBCT before surgical procedures.Item Gray value measurement for the evaluation of local alveolar bone density around impacted maxillary canine teeth using cone beam computed tomography(2021) Secgin, Cansu Koseoglu; Karslioglu, Hazal; Ozemre, Mehmet Ozgur; Orhan, Kaan; 34162816Background: To investigate whether any relationship between local alveolar bone density and maxillary canine impaction using gray values from cone beam computed tomography. Material and Methods: The cone beam computed tomography images of 151 patients were retrospectively evaluated. Maxillary canine was defined as an impacted tooth when root formation was complete and the patient's age older than 13 or the other side of the maxillary canine has completely erupted. Similarly, complete eruption was defined as the tooth in its expected occlusion and position. Using the cone beam computed tomography software, the region of interest which was 5 mm2 in area, was placed in the trabecular bone on cross sectional cone beam computed tomography images and the gray value measurements were recorded. After measuring the gray values of all the teeth, the images were grouped according to the field of view size. Comparison of the gray values of impacted and non-impacted teeth was made between images with the same field of view size. Results: A total of 151 patients, 101 (66.9%) female and 50 (33.1%) male, were included in the study. The mean age of the patients was 24.94 +/- 13.9. In images with a 40X40 field of view, the gray values of the impacted canine teeth were higher than the gray values of the non-impacted ones and statistically significant difference was found between them (p= 0.003). However no statistically significant difference was found between the gray values of impacted and non-impacted canine teeth in 60x60 and 100x50 field of view (p= 0.197, p= 0.170, respectively). Conclusions: We suggest using the smallest field of view size when evaluating bone density using gray values from cone beam computed tomography images and we support the idea that the local increased bone density may influence on impaction.
