The Journal of the Michigan Dental Association

This feature explores the integration of Cone Beam Computed Tomography (CBCT) into dental practice, offering guidelines for best practices. Introduced in 2001, CBCT revolutionized dental radiography, impacting various clinical areas. The article emphasizes the need for clinicians to comprehend CBCT technology, its benefits, and potential risks. It delves into CBCT imaging considerations, technical parameters (Field of View, Voxel Size, Spatial and Contrast Resolution), image viewing, artifacts, machine calibration, and service. Addressing radiation dose, risks, and protection, the article outlines decision-making for 2D vs. 3D imaging. It underscores the responsibility of interpreting CBCT images, legal considerations, return on investment, and the …

The Pharyngeal Airways Of Patients With Class Ii Malocclusion: A Cone-Beam Computed Tomography Analysis, Yazgı Ay Ünüvar, Fundagül Bilgiç Zortuk, Törün Özer, Kadir Beycan

Makara Journal of Health Research

Background: This study aimed to compare the minimum axial (min Ax) area and the volumes of the nasopharyngeal (NP) and oropharyngeal (OP) airways of patients with Class II malocclusion with different sagittal positions of the mandible and maxilla and patients with Class I malocclusion with normal jaw positions.

Methods: Airway areas and volumes of 51 patients with Class I malocclusion with normal maxillary and mandibular positions (0 < ANB < 4, 84 > SNA > 80, and 82 > SNB > 78) were compared with 21 patients with Class II malocclusion with normal maxillary and retrognathic mandibular positions (ANB>4, 84>SNA>80, and SNB4, SNA>84, …

Effects Of Ectodermal Dysplasia On The Maxilla: A Study Of Cone-Beam Computed Tomography, Beyza Karadede Ünal

Makara Journal of Health Research

Background: This study aimed to examine the effects of ectodermal dysplasia (ED) on the transverse width of the maxillary bone.

Methods: The ED group was composed of seven people, while the control group consisted of retrospective cone-beam computed tomography images of seven individuals with skeletal class 1 relationship. Images on the sagittal planes were taken, and cross-sections were taken from the longest point of the Anterior Nasal Spine-Posterior Nasal Spine line. The distance between the distal anterior canine teeth from the right buccal cortical bone to the left buccal cortical bone was measured. At the posterior region, the …

Evaluation Of The Frequency Of Mucous Retention Cysts In The Maxillary Sinus In A Turkish Population Using Cone-Beam Computed Tomography, Nihat Lacin, Birkan Tatar

Makara Journal of Health Research

Background: Mucous retention cyst (MRC) of the maxillary sinus (MS) is an asymptomatic pathology generally found during routine radiographic examination. This study aimed to investigate the frequency of MRCs in the MS from a Turkish population using randomly selected cone-beam computed tomography (CBCT) images. Methods: CBCT images of randomly selected systemically healthy subjects (n = 300; of which 156 were men and 144 were women with a mean age of 40.18 [age range: 18–65 years]) were included in this retrospective study. The images were evaluated, and MRC was detected as a dome-shaped radiopaque lesion on the floor or walls of …

Chulalongkorn University Dental Journal

Objectives The aim of this study is to evaluate the technical image quality and radiation dose of the DentiiScan 2.0 cone-beam computed tomography (CBCT) scanner before widespread clinical use. Materials and methods Image quality was measured for 4 scanning protocols of the DentiiScan 2.0, using 2 dedicated test objects: the SEDENTEXCT IQ phantom and the QRM-ConeBeam phantom. The following image quality parameters were evaluated: contrast-detail, contrast-to-noise ratio (CNR), spatial resolution, grey value uniformity, metal artefacts, and geometric accuracy. Radiation dose was measured using a calibrated ionization chamber placed at the isocenter of rotation, allowing for the calculation of the dose-area …
