surgical procedure for removal of impacted teeth is a challenge for clinicians as it involves accuracy in the diagnosis and localization of the dental elements. the cone-beam computed tomography (cbct), compared to the conventional radiography, has a greater potential to provide complementary information because of its three-dimensional (3d) images, reducing the possibility of failures in surgi...

mandibular canal is the most important anatomical landmark in the body of mandible which always must be considered for implant surgery in posterior mandibular region. damage to vessels and inferior alveolar nerve that passes through the mandibular canal can cause problems such as hemorrhage and neurosensory disturbances. damage to the mandibular canal can occur during implant surgery. depending...

Introduction: Knowledge of the presence of the alveolar antral artery in the lateral maxillary sinus wall is essential for surgeons who operate in this region. The purpose of this study was to investigate the correlation between alveolar antral artery diameter and lateral maxillary bony wall thickness in dentate patients.   Materials and Methods: Thirty five Cone-Beam Computed Tomography (CBCT)...

Three dimensional computed tomography is a computationally intensive procedure, requiring large amounts of R A M and processing power. Parallel methods for two dimensional computed tomography have been studied, but not edended or applied to 3D cone beam tomography. A discussion on how the 3D cone beam tomography problem can be implemented in parallel using MPI is given. W e show an improvement ...

background: providing a cross-sectional image is essential for preimplant assessments. computed tomography (ct) and cone beam ct (cbct) images are very expensive and provide high radiation dose. tangential projection is a very simple, available, and low-dose technique that can be used in the anterior portion of mandible. the purpose of this study was to evaluate the accuracy of tangential proje...

The incidence of condylar fractures is high and the condylar fractures can be seen different types. Cone beam computed tomography (CBCT), conventional radiographic techniques such as orthopantomography (OPG) can be used in diagnosis of the fracture. CBCT is relatively a new imaging modality and uses commonly in dental implantology. In our study, it is aimed to present detailed the imaging of co...

The recent surge of interest by both cardiologists and patients in electron beam computed tomography, an imaging technique developed in the 1970s, stems from reports about its excellent ability to depict high grade coronary artery stenoses and its capability to quantify coronary calcification and monitor the development of calcific deposits. This editorial will focus on the current evidence ind...

Purpose: The objective of this study was to investigate the prevalence of pituitary calcifications using cone beam computed tomography in a group of Turkish individuals. Material and methods: Cone beam computed tomography scans in the axial, coronal and sagittal planes of the pituitary gland of 284 patients were examined for evidence of pituitary calcification. Results: In the cone beam compute...

fewer than 15% of lipomas occur in the head and neck. lipomas of the larynx are very rare benign laryngeal tumors (0.6%). to date less than 100 case of laryngeal lipoma have been reported in the literature.clinical manifestation include progressive horseness, dyspnea, and even dysphagia. in the direct exam smooth or pedunculated mass is seen in the larynx and sometimes if tumor is large enough ...
