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, Pelin
Objective: 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.
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; 34162816
Background: 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.
The Radiological Evaluation of Posterior Superior Alveolar Artery by Using CBCT
(2021) Karslioglu, Hazal; Citir, Mesude; Gunduz, Kaan; Kasap, Pelin; 32598262
Background: Evaluation of the maxillary sinus anatomy prior to sinus lift procedures is important to avoid surgical complications due to the close anatomical relationship between the posterior maxillary region and the maxillary sinus. Introduction: In order to avoid traumatizing the posterior superior alveolar artery and to prevent perioperative bleeding, locating the exact position of the artery is imperative before the surgical procedures. Methods: 150 CBCT scans were evaluated. The distance from the inferior border of the PSAA to the alveolar crest (the vertical line from the artery to the crest) and floor of the maxillary sinus, the distance from PSAA to medial sinus wall, nasal septum, zygomatic arch, position, the distance from the floor of maxillary sinus to the alveolar crest and diameter of the PSAA were assessed. Locations of the artery were classified. Results: The artery diameters were mostly >= 1 mm. The artery was mostly intraosseous (59.7%), 21.7% was superficial and only 18.7% was intra-sinuscular. Conclusion: The location of PSAA is intraosseous in most patients. The artery diameters were mostly >= 1 mm and we can say that increasing the size also increases the risk of complications.
