Our aim was to evaluate haptic virtual reality (VR) simulation with repetitive training as a tool in teaching caries removal (CR) and periodontal pocket probing (PPP) skills. For the CR simulation, multilayered virtual models composed of tooth substance, caries, and pulp were developed. Seven students completed three training sessions each, which were scored based on the volume of the cut region, the number of instances of handpiece overload, and total cutting time. For the PPP task, we developed a virtual periodontal disease model and 26 students received training in measuring pocket depth. Pocket probing force was measured and proficiency was evaluated. In the CR task, scores for the second and third training sessions were significantly higher than for the first training session. We likewise obtained effective repetitive training results for the PPP task. Our simulator was effective at teaching hand skills for both tasks within short-term evaluation.

“…Recently, digital simulations with haptic devices have been utilized in education to train medical students prior to their interaction with real patients 39) . These training systems are extensively used across various dental fields, including restorative dentistry, prosthodontics, maxillofacial surgery, and implantology [40][41][42][43][44] . In training simulations, the ability to change and display the situation in real time is essential, emphasizing the significance of the calculation speed 45) .…”

Traditionally, simulation studies in dentistry have relied on the finite element method (FEM). However, the smoothed particle hydrodynamics (SPH) method, which represents objects as particle collections without the use of meshes, has gained recent attention. Despite its application in dentistry, there is currently a lack of comprehensive literature summarizing the specific applications of the SPH method in the oral region. This review aims to provide a summary of studies that have utilized the SPH method in dentistry, focusing on its applications in analyzing large deformations, such as dental ceramic collisions, soft material analysis (e.g., denture adhesive), and virtual training simulations for dental treatments. By combining the advantages of the SPH and FEM methods, more accurate simulations can be achieved, and further applications of the SPH method in dentistry are anticipated.

“…For example, a search in Scopus including the terms "3D" and "dental education" reveals only one paper in the year 2000 containing those terms; while 14 appeared in the year 2019 and 11 have been published so far in 2020. A review of the literature shows that 20 papers describe new software or novel uses of 3D technology for dental education [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] and 10 focus on students' perception of the use of 3D tools [19,30,[35][36][37][38][39][40]. However, only eight were comparative studies [35,38,[40][41][42][43].…”

3D Technology Development and Dental Education: What Topics Are Best Suited for 3D Learning Resources?

2020

View full text Add to dashboard Cite

The aim of this study is to identify topics (knowledge and skills) from the dental curricula that would benefit from having a 3D learning resource using an exploratory sequential design method. The first phase targeted stakeholders from a Scottish dental school. Seven focus groups and three interviews disclosed 97 suitable topics for 3D technology development. These results were used to construct a survey that was sent to final year dental students, newly dental graduates and academics from three Scottish universities. The survey asked participants to rank each item based on the perceived benefit that a 3D learning resource would have for dental education. Results revealed that detailed anatomy of the temporomandibular joint, dental anaesthesiology, dental clinical skills techniques, dental occlusion and mandibular functioning were top priorities. Gender differences only appeared in relation to ‘Extraction techniques: movements and force’ (p < 0.05), this topic was considered to be more beneficial by females than by males. No statistical difference was found when comparing results of graduates with undergraduates. These results serve as a starting point when developing a new 3D technology tool for dental education, considering users demands and perceived needs has the potential to benefit dental students and dental education directly.
