The cone beam computed tomography (CBCT) image provides clear differentiation of soft tissues from empty spaces. This paper presents a literature review to evaluate the effects of orthopedic and surgical treatment on the pharyngeal dimension by CBCT. It was concluded that treatments involving dentofacial orthopedics and orthognathic surgery have been related with an increase in the upper airway volume. Standardized capturing of tomographic images and more controlled and randomized studies are necessary.

Bilateral inverse canine impaction: a case report.

J Med Case Rep

December 2024

School of Dentistry, China Medical University, Taichung, 404, Taiwan, Republic of China.

Background: Maxillary canine impaction can result in malocclusion, temporomandibular joint complications, and esthetic concerns, thus influencing craniofacial development. Although cases of impacted canines are not uncommon in clinical practice, the likelihood of simultaneous bilateral impaction is extremely low; very few reports have documented cases of bilaterally symmetrical, inversely impacted canines.

Case Presentation: This paper reports a rare case of maxillary canine impaction, a condition characterized by the abnormal eruption of teeth.

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.

Introduction: The dentoskeletal effects of clear aligner treatment (CAT) with Invisalign vs temporary skeletal anchorage device-anchored Sydney intrusion spring (SIS) were compared in consecutively treated growing patients with anterior open bite using cone-beam computed tomography scans.

Methods: Fifteen adolescents treated exclusively with Invisalign, and 14 with SIS (first-phase treatment) were assessed retrospectively. Rigid-wise, voxel-based registration of pretreatment and posttreatment cone-beam computed tomography scans were performed using the anterior cranial base, maxillary plane, and mandibular body as reference regions.

Investigating paranasal sinuses developmental disorders and septum deviation angle effects on olfactory fossa depth using cone-beam computed tomography.

Dent Res J (Isfahan)

November 2024

Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Islamic Azad University, Isfahan (Khorasgan) Branch, Isfahan, Iran.

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.
