The Current Situation and Future Prospects of Simulators in Dental Education

A study to investigate the effectiveness of the application of virtual reality technology in dental education

BACKGROUND

Today, the use of virtual reality (VR) technology as an educational tool in dental education has expanded considerably. This study was aimed to evaluate the effectiveness of using VR technology in teaching neutral zone and teeth arrangement.

METHODS

This randomized trial was conducted at Kermanshah University of Medical Sciences, Iran in 2019. The study sample consisted of 50 six-year dental students who were randomly divided into experimental (n = 25) and control (n = 25) groups. Students' performance in both groups was assessed using tests. A questionnaire was used to assess the usability of VR technology and students' satisfaction with it.

RESULTS

All faculty members confirmed the usability of VR technology in dental education. The majority of students (76%) were highly satisfied with the use of this technology in their learning process. The mean score of students was significantly higher in the experimental group (16.92 ± 1.12) than in the control group (16.14 ± 1.18).

CONCLUSION

In general, it can be argued that VR technology is useful and effective in the teaching-learning process. Therefore, its use in medical and dental schools can play an effective role in creating a dynamic, attractive, and successful learning environment.

Scoping review of artificial intelligence and immersive digital tools in dental education

PURPOSE

The aim of this scoping review is to examine artificial intelligence (AI) and virtual teaching models within the context of dental education, establish methods to address the resources being investigated, and ultimately augment this approach for future scientific research.

METHODS

To evaluate the applications of AI and immersive technology, a scoping literature review was conducted using the Embase, PubMed, Web of Science, and Cochrane Library database from the years 2018 to May 19, 2021. Additionally, a manual search was completed. The search strategy was formulated according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Studies that addressed the current uses of virtual devices and their revolutionary potential in dental education were categorized separately for further evaluation.

RESULTS

 Of the 2500 articles found in our initial search results, 31 articles met the inclusion criteria set for this review. The selected studies were directly related to AI and immersive tools in dental education.

CONCLUSION

To our knowledge, there are very few comprehensive literature reviews identifying the applications and efficacy of virtual and AI-driven tools in dental education. With limited verifiable evidence, an improved understanding of virtual and AI domains is needed to enable dental students to adapt to changes within and beyond their dental training education. To increase the scientific value of digital-related research, the scientific community must quickly define guidelines to enhance methodological approaches in order to effectively digitalize dentistry.

Virtual Reality as parent education tool in pre-surgical management of cleft lip and palate affected infants-A pilot study

AIM

To assess the influence of virtual reality (VR) in parent acceptance of the pre-surgical nasoalveolar molding (PNAM) as a pre surgical care to the cleft lip and palate affected infants.

MATERIAL AND METHODS

Descriptive Cross sectional pilot study design was planned to assess the pre surgical management of the cleft lip and palate. Twenty parents/caregivers of the infants were randomly divided into two groups. Twelve participants received education through conventional education module (Group I) using verbal explanation supported by the photographs. Another 12 participants received education through customized VR based educational video (Group II). After the education, the parents were provided with questionnaire to assess the acceptance of the treatment procedure. The survey response rate was represented in percentage.

RESULTS

The results of the study indicated that most of the parents were aware of the feeding plate or obturators as an aid in assisting feeding practices among cleft lip and palate affected infants. However, only 33% of participants in Group I were able to understand the doctor's explanation regarding the PNAM whereas 100% of participants in Group II were able to visualize the benefits of PNAM. These participants were willingly accepting PNAM as essential pre-surgical care.

CONCLUSION

Innovative approaches are essential in patient education modalities as the success of any treatment outcome largely depends on the patient acceptance. Within the limits of this study, VR has been successful in the educating the parents and caregivers regarding the acceptance of PNAM therapy in cleft affected infants.

Review on visualization technology in simulation training system for major natural disasters

Major natural disasters have occurred frequently in the last few years, resulting in increased loss of life and economic damage. Most emergency responders do not have first-hand experience with major natural disasters, and thus, there is an urgent need for pre-disaster training. Due to the scenes unreality of traditional emergency drills, the failure to appeal to the target audience and the novel coronavirus pandemic, people are forced to maintain safe social distancing. Therefore, it is difficult to carry out transregional or transnational emergency drills in many countries under the lockdown. There is an increasing demand for simulation training systems that use virtual reality, augmented reality, and mixed reality visualization technologies to simulate major natural disasters. The simulation training system related to natural disasters provides a new way for popular emergency avoidance science education and emergency rescue personnel to master work responsibilities and improve emergency response capabilities. However, to our knowledge, there is no overview of the simulation training system for major natural disasters. Hence, this paper uncovers the visualization techniques commonly used in simulation training systems, and compares, analyses and summarizes the architecture and functions of the existing simulation training systems for different emergency phases of common natural disasters. In addition, the limitations of the existing simulation training system in practical applications and future development directions are discussed to provide reference for relevant researchers to better understand the modern simulation training system.

Effectiveness of Virtual Reality-Based Training on Oral Healthcare for Disabled Elderly Persons: A Randomized Controlled Trial

(1) Background: Virtual reality (VR) technology is a widely used training tool in medical education. The present study aimed to evaluate the effectiveness of VR training of oral hygiene students on providing oral healthcare to disabled elderly persons. (2) Methods: A randomized controlled trial was conducted. In 2021, oral hygiene students were randomly assigned to a VR experimental group (EG; n = 11) and a control group (CG; n = 12). The EG received two-hour, thrice-repeated VR-based training interventions at 2-week, 4-week, and 6-week follow-ups. The CG received no VR-based interventions. Data were collected using a self-administered questionnaire before and immediately after each intervention. We performed generalized estimating equations to compare the responses. (3) Results: The EG exhibited a more significant improvement in oral care-related knowledge, attitude, self-efficacy, and intention at the 6-week follow-up than the CG. The students’ intention to assist the elderly in using interdental brushes (β = 0.91), with soft tissue cleaning (β = 0.53), and with oral desensitization (β = 0.53), and to have regular dental visits (β = 0.61) improved significantly at the 6-week follow-up. (4) Conclusions: VR training positively affected students’ knowledge, attitude, self-efficacy, and intentions on providing oral healthcare to disabled elderly persons.
