The use of CBCT in orthodontics with special focus on upper airway analysis in patients with sleep-disordered breathing. Dentomaxillofac Radiol 2024; 53:178-188. [PMID: 38265247 PMCID: PMC11003665 DOI: 10.1093/dmfr/twae001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 11/14/2023] [Accepted: 12/29/2023] [Indexed: 01/25/2024] Open
Abstract
Applications of cone-beam CT (CBCT) in orthodontics have been increasingly discussed and evaluated in science and practice over the last two decades. The present work provides a comprehensive summary of current consolidated practice guidelines, cutting-edge innovative applications, and future outlooks about potential use of CBCT in orthodontics with a special focus on upper airway analysis in patients with sleep-disordered breathing. The present scoping review reveals that clinical applications of CBCT in orthodontics are broadly supported by evidence for the diagnosis of dental anomalies, temporomandibular joint disorders, and craniofacial malformations. On the other hand, CBCT imaging for upper airway analysis-including soft tissue diagnosis and airway morphology-needs further validation in order to provide better understanding regarding which diagnostic questions it can be expected to answer. Internationally recognized guidelines for CBCT use in orthodontics are existent, and similar ones should be developed to provide clear indications about the appropriate use of CBCT for upper airway assessment, including a list of specific clinical questions justifying its prescription.

Kim DH. Distance versus face-to-face education of gross anatomy for dental hygiene students: Perceptions and academic achievements of learners. Clin Anat 2023; 36:1016-1026. [PMID: 37476934 DOI: 10.1002/ca.24097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 06/12/2023] [Accepted: 06/29/2023] [Indexed: 07/22/2023]
Abstract
The provision of distance education has increased rapidly over the past few years owing to the COVID-19 pandemic. The core of gross anatomy distance education is three-dimensional (3D) visualization of anatomical structures, and the use of simple 3D visualization tools has increased as distance education has become more popular. The purpose of this study was to establish a more effective operation plan in dental hygiene by investigating learners' opinions about distance education of gross anatomy and 3D visualization tools, and by comparing and analyzing their academic achievements. The study involved 250 students and comprised an analysis of 120 students who took a head and neck anatomy class at the Department of Dental Hygiene at D University via distance learning during 2020-2022, and 130 graduates who had completed the class via face-to-face learning during 2015-2017. An online survey of 120 of the enrolled students comprised 10 questions asking for opinions on the head and neck anatomy distance learning classes, five questions on the 3D visualization tool, and five on general characteristics. Overall, the learners had positive perceptions of distance education for head and neck anatomy and the 3D visualization tool. Among the education methods compared, they generally preferred blended learning (n = 47, 39.2%). There was a significant preference for the distance learning method of asynchronous classes (n = 86, 94.5%). Analysis of academic achievements according to whether or not distance education was conducted revealed a significantly higher score in the face-to-face class group (P < 0.05). A blended learning method can be effective in increasing learner satisfaction and improving academic achievement in gross anatomy classes on dental hygiene. It is suggested that theoretical material should be learned through asynchronous content and knowledge expanded through small-group activities during face-to-face learning. This will help establish a standard model for teaching of gross anatomy in dental hygiene in the postpandemic era.

Abstract
Background and Objectives: The ever more complex modern dental education requires permanent adaptation to expanding medical knowledge and new advancements in digital technologies as well as intensification of interdisciplinary collaboration. Our study presents a newly developed computerized method allowing virtual case simulation on modular digital dental models and 3D-printing of the obtained digital models; additionally, undergraduate dental students' opinion on the advanced method is investigated in this paper. Materials and Methods: Based on the digitalization of didactic dental models, the proposed method generates modular digital dental models that can be easily converted into different types of partial edentulism scenarios, thus allowing the development of a digital library. Three-dimensionally printed simulated dental models can subsequently be manufactured based on the previously obtained digital models. The opinion of a group of undergraduate dental students (n = 205) on the proposed method was assessed via a questionnaire, administered as a Google form, sent via email. Results: The modular digital models allow students to perform repeated virtual simulations of any possible partial edentulism cases, to project 3D virtual treatment plans and to observe the subtle differences between diverse teeth preparations; the resulting 3D-printed models could be used in students' practical training. The proposed method received positive feedback from the undergraduate students. Conclusions: The advanced method is adequate for dental students' training, enabling the gradual design of modular digital dental models with partial edentulism, from simple to complex cases, and the hands-on training on corresponding 3D-printed dental models.

Abstract
Recent studies have shown that global variation in body proportions is more complex than previously thought as some traits formerly associated with climate adaptation are better explained by geographic proximity and neutral evolutionary forces. While the recent incorporation of quantitative genetic methodologies has improved understanding of patterns related to climate in Africa, Europe, and the Americas, Asia remains underrepresented in recent and historic studies of body form. As ecogeographic studies tend to focus on male morphology, potential sex differences in features influenced by climate remain largely unexplored. Skeletal measurements encompassing the dimensions of the skull, pelvis, limbs, hands, and feet were collected from male (n = 459) and female (n = 442) remains curated in 13 collections across seven countries in East Asia (n = 901). Osteological data were analyzed with sex and minimum temperature as covariates adjusted by autosomal single-nucleotide polymorphism population genetic distance using univariate Bayesian linear mixed models, and credible intervals were calculated for each trait. Analysis supports a relationship between specific traits and climate as well as providing the magnitude of response in both sexes. After accounting for genetic distance between populations, greater association between climate and morphology was found in postcranial traits, with the relationship between climate and the skull limited primarily to breadth measurements. Larger body size is associated with colder climates with most measurements increasing with decreased temperature. The same traits were not always associated with climate for males and females nor correlated with the same intensity for both sexes. The varied directional association with climate for different regions of the skeleton and between the sexes underscores the necessity of future ecogeographic research to holistically evaluate body form and to look for sex-specific patterns to better understand population responses to environmental stresses.

Abstract
It is essential for dental hygienists to have basic knowledge of gross anatomy to provide efficient treatment. However, gross anatomy course is relatively neglected due to their disparity from actual clinical dental practice. This study aimed to propose an effective dental hygiene gross anatomy curriculum that reflects the opinions of professional clinical dental hygienists. The study had an online-based cross-sectional design and the survey was distributed to clinical dental hygienists via social networks (n = 200). The questionnaire consisted of questions on the utilization of anatomical knowledge in clinical practice, opinions on the contents and methods of gross anatomy education, and general characteristics. The present study found that 186 (93%) used anatomical knowledge at an above-average level. Qualitative analysis indicated that dental implant surgery, radiography, and extraction were the clinical procedures that required the most anatomical knowledge. The clinical dental hygienists answered that the most-necessary knowledge is that of the mandibular nerve, followed by that on the temporomandibular joint, mandible, maxilla, maxillary nerve, and masticatory muscle. The methods proposed to improve gross anatomy education were (in decreasing order of importance) using videos or photographs (X-rays, CT, MRI, etc.), integrating education with clinical subjects, and using a three-dimensional visualization program. Higher education levels of respondents have increased their tendency to believe that the contents and methods of the presented education were necessary. Dental hygienists who utilized anatomical knowledge more often tended to be had a greater appreciation of the necessity of all educational contents and methods.

[PMID: 33650773 DOI: 10.1002/ase.2066] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 02/18/2021] [Accepted: 02/24/2021] [Indexed: 06/12/2023]
Abstract
E-learning is an educational method that improves knowledge innovation by sharing relevant images for advanced learning, especially in a pandemic state. Furthermore, cone-beam computed tomography (CBCT) is a method that gathers medical or dental diagnostic images. This study aimed to analyze the effectiveness of dental anatomy education through a CBCT technology tool, through teachers' and students' perspectives, adjusted according to the disruptions caused by the Covid-19 pandemic. A cohort study and longitudinal exploratory analysis were performed. Forty undergraduate first-year dental students, from the University of Coimbra in Portugal, were selected as per the inclusion and exclusion criteria. Two different teaching methods were applied during an identical time-period: face-to-face lectures complemented by physical models (T1 cohort) and webinar lectures complemented by CBCT images (T2 cohort). Learning outcomes were then studied according to theoretical and spatial orientation contexts. A self-reported survey that focused on students' satisfaction, stress, and support was studied. Both teaching methods were analyzed with paired sample student's t-test and Pearson Correlation Confidence intervals 95% with P < 0.05. Furthermore, exploratory factor analysis (EFA) was used for self-reported satisfaction survey validity and reliability analysis. The learning outcomes between T1 and T2 cohorts were statistically significant, (P < 0.001) corresponding to differences with a large effect degree (r > 0.60). Students' satisfaction, as measured on a six-point Likert scale, was positively influenced by the webinar lectures supplemented with CBCT images (T2 cohort) in a learning context (4.95 ± 0.5) and future applications (5.92 ± 0.27). In conclusion, the webinar approach with CBCT images was more effective and better learning method for teaching dental anatomy.

Abstract
OBJECTIVES The present work describes the status and contents of The Human Bone Collection of the Faculty of Dentistry at the University of Hong Kong. MATERIALS AND METHODS The Collection originates from the 1980s and became officially established in 2017 for teaching and research purposes. Most of the Collection consists of unclaimed human remains of southern Chinese individuals exhumed from local cemeteries and donated to the Faculty in the last few decades. The demographic information was provided largely from burial records and forensic estimations. Since 2016, the Collection has undergone a process of reorganization into cranial and postcranial remains, followed by preservation procedures that included cleaning and classification. RESULTS The Collection currently consists of remains belonging to about 368 individuals (243 males, 54 females, 71 unknown), with ages ranging from 0.8 to 90 years (mean 57.4 years). It comprises cranial remains belonging to 260 individuals (169 males, 39 females, 52 unknown), and postcranial remains belonging to 248 individuals (180 males, 42 females, 26 unknown). The preservation status ranges from poor to good, with the cranial remains better preserved than the postcranial elements. For a large number of individuals, ear ossicles, soil samples, and other materials are also available. DISCUSSION The Collection is accessible to local and international institutions for teaching and research.
