Abstract

Background and Objective: Many surgeries are performed on anterior region of mandible. Incisive branch of the inferior alveolar nerve is located in the anterior region of mandible. The identification of various form of nerve is important for diagnosis and treatment plan. This study was carried out to the assessment of visibility and extension rate of incisive branch of the inferior alveolar nerve in cone beam computed tomography (CBCT) imagings. Methods: This descriptive – analytic study was performed on 105 CBCT images. The presences or absence of incisive branch of the inferior alveolar nerve and assessment of visibility and extension rate of mandibular incisive canal were studied. Results: In 79% extension of the incisive branch of the inferior alveolar nerve were observed. 18.07% of extensions were observed in one-side and 78.31% were bilateral. Extension of the incisive branch of the inferior alveolar nerve was observed to central, lateral and canine tooth in 59%, 26.5% and 14.5% respectively. There was no significant relation beween gender and age of subjects with extension of the incisive branch of the inferior alveolar nerve. Conclusion: Regarding the high visibility of the incisive nerve branches in the lower dental CBCT images this method can be used to evaluate the anterior region of mandible.

Abstract

Understanding maxillary sinus hypoplasia (MSH) and associated sinonasal variants is crucial for the success of diagnostic and therapeutic procedures in maxillary sinus and maxillary dental implant surgery. The aim of this study was to investigate a rare case of unilateral maxillary sinus hypoplasia associated with lower orbital floor displacement, without involving the Uncinate process. A 31-year-old woman presented to the Department of Oral and Maxillofacial Surgery at Babol Dental School for rhinoplasty without any complaints of headache or nasal congestion. She had no history of trauma, congenital or bone diseases/abnormalities. Cone Beam Computed Tomography (CBCT) images revealed left maxillary sinus hypoplasia, lower orbital floor, and increased thickening of the sinus mucosa. The patient's photograph also showed lower displacement of the orbital floor. The diagnosis of unilateral maxillary sinus hypoplasia in this study was based on clinical manifestations and coronal views of CBCT and CT scans. Symptoms of hypoplastic sinus include chronic headache, facial pain, voice problems, or may sometimes be asymptomatic. If the surgeon is not aware of the hypoplasticity of the sinus, complications during surgery may increase, including post-surgery complications such as visibility of the low orbital floor and resulting patient confusion. This study highlights the importance of using CBCT as a valuable diagnostic tool to identify anatomical variations and details of the hypoplastic sinus. This approach helps the surgeon to inform the patient and provide an appropriate treatment plan, especially in cases involving dental implants or sinus surgery.

Abstract

Background and Objective: Sinus extension is a physiological process that occurs in the growth cells of the paranasal sinuses and leads to increasing their volume over time, causing challenges in the dental implant process. This study was conducted to evaluate maxillary sinus morphometrics by cone-beam computed tomography (CBCT).
Methods: This descriptive-analytical study was conducted on the CBCT images of 100 people (52 male and 48 female) with a mean age of 45.32 ± 17.41 and the age range of 27 to 63 years referring to an oral and maxillofacial specialized radiology clinic in Babol, Iran during 2019. The amount of maxillary sinus extension in the panoramic-like view was recorded based on the amount of its extension in terms of the first anterior tooth and the last posterior tooth. In the new net technologies (NNT) software, in the section related to creating panoramic-like views, first, in the axial sections, the starting point of the maxillary sinus was specified from the occlusal side, and the mediolateral dimensions were measured at distances of 3 mm above and 3 mm below.
Results: The highest amount of maxillary sinus progress in the right anterior side was related to the mesial of tooth 5 (15%), and the highest amount of sinus progress in the left anterior side was related to the distal of tooth 3 (15%) and the mesial of tooth 4 (15%), which had no statistically significant differences. The most progress in the anterior area was related to the distal of the canine tooth and the mesial of the first premolar. The mean mediolateral sinus progress at 3 mm above the right nasal floor was higher in females than in males (P<0.05). Gender and age had no statistically significant relationship with maxillary sinus progress.
Conclusion: The maxillary sinus progress was almost equal in the left and right sides and also in males and females.
