Objectives: This study aimed to evaluate the position of the mandibular lingula (ML) in adult patients (aged between 18 and 35 years old) with different skeletal and growth patterns using cone-beam computed tomography (CBCT).
Design: Cross-sectional.
Setting: Dentistry department of University.
Article Synopsis
- The size of the field of view (FOV) in cone-beam computed tomography (CBCT) impacts both image quality and patient radiation dose, necessitating careful selection based on therapeutic goals.
- The study assessed how different FOV sizes affect the contrast-to-noise ratio (CNR) across five different CBCT units using scanned images from a dried human mandible with simulated soft tissue.
- Results indicated that smaller FOVs significantly reduced CNR (P<0.05), highlighting a direct relationship between FOV size and image quality, although variations in exposure settings across devices affected the CNR outcomes for similarly sized FOVs.
Background: Considering the adverse consequences of respiratory insufficiency in cleft lip and palate (CLP) patients, this study aimed to assess the pharyngeal airway dimensions in 9-12-year-old patients with unilateral CLP. This historical cohort evaluated the cone-beam computed tomography (CBCT) scans of 30 patients with non-syndromic unilateral CLP between 9 and 12 years and 30 age- and sex-matched non-cleft controls. Three-dimensional (3D) images were reconstructed by the Mimics software, and the nasopharyngeal, oropharyngeal, and total airway volumes, as well as the minimal cross-sectional area of the airway (minAx), and posterior airway length (PAL) were all measured in the sagittal plane.

The location of the mandibular foramen (MF) on digital panoramic radiographs can be an important guide for clinicians when administering the inferior alveolar nerve block (IANB) for dental anesthesia of the mandible. This study, aimed to assess the location of the MF relative to the anterior border (AB) of the ramus and the occlusal plane (OP) from digital panoramic radiographs. An observational case series study was conducted on digital panoramic radiographs from the oral and maxillofacial radiology department archives of patients at least 18 years of age with a 1:1 scale (100%).

Materials And Methods: In this ex vivo diagnostic study, one-millimeter defects were created in the alveolar sockets of 15 bone blocks, each with two posterior teeth. A no-defect control group was also included.
