Introduction: The aim of this study was to determine the incidence and morphometric and morphological characteristics of fossa navicularis (FN) on cone beam computed tomography (CBCT) images of healthy adults MATERIALS AND METHODS: CBCT images of 900 individuals (450 males, 450 females, over the age of 18) admitted to Gaziantep University, Dentistry Faculty were retrospectively examined. The incidence and shape of FN were determined. Transverse diameter (TDFN), sagittal diameter (SDFN), depth in transverse section (DFNT), depth in sagittal section (DFNS), and the shortest distance between the deepest point of FN and intracranial cavity (FNI) were measured.
Results: FN was detected in 122 (59 males and 63 females) of 900 (13.56%) CBCT images. No statistically significant difference was observed between gender and the incidence of FN. SDFN, TDFN, DFNS, DFNT and FNI were measured as 4.04 ± 1.71, 4.28 ± 1.34, 1.79 ± 0.68, 2.34 ± 0.85, and 6.76 ± 2.23 mm, respectively. Besides, FN was described as oval in 95 of 122 (77.87%) cases, while as round in 27 (22.23%) cases.
Conclusions: The incidence of FN is rare; however, it may be responsible for serious consequences by causing infections from the nasopharynx to the intracranial cavity. As far as we know, the distance between the deepest point of FN and the intracranial cavity was measured for the first time in the literature with this study.

Background: This study aims to evaluate the impact of different thresholds and voxel sizes on the accuracy of Cone-beam computed tomography (CBCT) tooth reconstruction and to assess the accuracy of fused CBCT and intraoral scanning (IOS) tooth models using curvature continuity algorithms under varying thresholds and voxel conditions.
Methods: Thirty-two isolated teeth were digitized using IOS and CBCT at two voxel sizes and five threshold settings. Crown-root fusion was performed using a curvature continuity algorithm.

Background: The ethmoid roof separates the ethmoid cells from the anterior cranial fossa. From the medial side, the roof of the ethmoid is connected to the lateral lamella of the ethmoid plate, which is the thinnest bone at the base of the skull and is most vulnerable to damage during endoscopic surgeries. The purpose of this study is to investigate the height of the lateral lamella in patients with hypoplasia/aplasia of the paranasal sinuses and deviation of the nasal septum using reconstructed multiplanar images by cone-beam computed tomography (CBCT).

Background: Dens invaginatus is a developmental abnormality originating from tooth development, including coronal invaginatus and radicular invaginatus. The reported incidence varies greatly due to diagnostic techniques, classification criteria and race. The incidence of dens invaginatus in China was not clear, and the impact of dens invaginatus on periodontal support tissue were rarely reported.

As maxillofacial surgery becomes increasingly digitized and the transformative impact of pre-surgical scanning and computer simulation is recognized, this clinical paper presents an algorithm for the selection of interventions in severe congenital oligodontia with Angle class-III malocclusion (OCIII) utilizing such technologies. A complex, multifactorial condition with varying degrees of craniofacial involvement, OCIII is associated with edentulous facial appearance, mandibular prognathism and deep underbite, as well as malocclusion. Our methodology involves the integration of CBCT imaging, intra- and extra- oral scanning, and 3D planning with the assessment of bone volume, number of missing teeth, skeletal discrepancies, and patient compliance in the selection of suitable treatments.

Purpose/objective: MR-only radiotherapy planning exploits the benefits of MRI soft-tissue delineation, whilst negating the registration inaccuracies caused by MRI CT fusion. Fiducial markers have conventionally been used in prostate radiotherapy to reduce on-treatment image matching variability. However, this is an invasive procedure for the patient, and presents technical difficulties in an MR-only pathway as fiducial markers are difficult to visualise on MRI.
