Objectives: The objectives of this study included using the cone beam computed tomography (CBCT) technology to assess: (1) intra- and inter-observer reliability of the volume measurement of the nasal cavity; (2) the accuracy of the segmentation protocol for evaluation of the nasal cavity.
Materials And Methods: This study used test-retest reliability and accuracy methods within two different population sample groups, from Eastern Asia and North America. Thirty obstructive sleep apnea (OSA) patients were randomly selected from administrative and research oral health data archived at two dental faculties in China and Canada.
Article Synopsis
- - The study aimed to compare the anatomical balance of the upper airway between Dutch and Chinese patients with obstructive sleep apnea (OSA) using cone beam computed tomography (CBCT) images, focusing on the ratio of the tongue area to maxillomandibular enclosure area.
- - Researchers included 28 Dutch and 24 Chinese adults with similar apnea-hypopnea indices (AHI), age, and body mass index (BMI), but found that the Dutch had larger tongue measurements while the Chinese had a smaller maxilla length.
- - Despite these differences in individual anatomical features, the overall upper airway anatomical balance was not significantly different between the two groups, suggesting that race may not play a crucial role in this aspect of OSA pathology
The objective of this study was to examine to what extent the anatomic characteristics of the upper airway can influence the effect of nocturnal wearing of dentures on the sleep of edentulous elders with untreated sleep apnea. This study used the data from a randomized crossover clinical trial and an exploratory approach to address its objectives. Cone beam computed tomography scans of 65 edentulous individuals (female, = 37; male, = 28; mean ± SD age, 74.

Second, to examine the correlation between the severity of OSA and the anatomic and aerodynamic characteristic(s) of the upper airway in these edentulous individuals.
Methods: NewTom5G cone beam computed tomography scans of 58 edentulous individuals with mild, moderate, and severe OSA were included in this analysis.
Background: The aim of this study was to compare the trabecular bone microstructures of anterior and posterior edentulous regions of human mandible using cone-beam computed tomography (CBCT) and micro computed tomography (µCT).
Methods: Twenty volumes of interests consisting of six anterior and fourteen posterior edentulous regions were obtained from human mandibular cadavers. A CBCT system with a resolution of 80 µm (3D Accuitomo 170, J.
