In the dental curriculum, the initial administration of local anaesthesia injection on live patients is critical and students may experience a high degree of anxiety. Low self-confidence often caused by insufficient knowledge of anatomy has been repeatedly reported as one of the major causes. In this paper, we focus on the development of a haptic t...

... the tip of the virtual needle has reached the area sur- rounding the nerve, the student can proceed to the injection of local anaesthesia by pressing button 1 of the haptic de- vice. As a result, the syringe plunger is pressed down and the anaesthetised area gradually turns red indicating the region has been numbed ( Figure 5). The procedure can be reset and the injection graphical outcomes removed by pressing the button 2 of the haptic device, and thus rehearsed repeatedly. ...

... the system can be enhanced with the provision of augmented information in the form of three points of view that could not be obtained throughout the training tradition- ally conducted in the real world. Additional points of view are provided in a side panel located on the left side of the monitor ( Figure 5): (1) The top view shows the mandible with the inferior alveolar and lingual nerves, which are rel- evant in this procedure; (2) The middle view shows a simi- lar viewpoint but includes other relevant structures ( parotid glands, buccinator, the superior pharyngeal constrictor and the medial pterygoid); (3) The bottom view consists of a close-up on the tip of the needle. According to behavioral psychologists, such aids may be beneficial at the early stages in the development of practical skills, however they have to be removed when the student achieves proficiency [Sch08]. ...

Objectives
Administering anesthesia to the inferior alveolar nerve is 1 of the most stressful processes in dental training. Most studies using virtual reality (VR) for dental training have used non‐immersive technologies. The purpose of this work is to assess the impact of immersive technologies on skills training.
Methods
On May 2019, an experimental study was conducted with 163 clinical dental students, divided into 4 groups across 2 phases (preceptorship and training) with haptic feedback either On or Off. The participants trained on the inferior alveolar dental anesthesia procedure in a haptic VR simulator. Their technical skills were evaluated in terms of needle insertion features which were computed from a haptic device providing kinematic data. Also, the participants reported their subjective experience with syringe handling and simulator sickness. A machine learning method was implemented to automatically evaluate the needle insertion point performance of the student.
Results
Groups receiving immersive preceptorship and/or immersive training showed more accuracy and confidence in administering the anesthesia. Participants perceived a high sense of realism with the haptic feedback when handling the syringe. The machine learning method was validated, with an accuracy of 84%, as a good classifier to assess a student's needle insertion point performance.
Conclusions
The immersive VR simulator allows the practice of the inferior alveolar nerve block under near real conditions and with immediate feedback to the dental student with respect to the needle insertion point. This machine learning based automatic evaluation provides a method to improve technical skills, contributing to dental training.

... In general, mannequins or mechanical simulators are used, but they are very far from the experience of applying anesthesia to a real patient. Simulators with haptic interfaces [Poyade et al. 2014 help in the development of tactile skills, but the existing ones are neither immersive nor offer evaluation and aid in the execution of the trajectories of instruments by the learner. In this context, an immersive and haptic environment for anesthesia training of the inferior alveolar nerve called VIDA Odonto ] was developed at the Interlab (Laboratory of Interactive Technologies) of the School of Engineering (Escola Politécnica) of USP, with FAPESP funding, in a collaboration with the LaSiT (Laboratory of Simulation and Training) of the School of Dentistry of Bauru (FOB-USP) and LApIS (Laboratory of Computer Applications in Healthcare) of the School of Arts, Sciences and Humanities (EACH-USP). ...
Training anesthetic application is a challenge for teaching dentistry, given the complexity of the procedure and the risks involved. Through an immersive virtual reality environment, the system presented here offers a playful way of learning, through game elements. This serious game allows the user to practice anesthesia technique with or without aids (tactile or visual) and to receive scores at different levels of difficulty. An important differential is the possibility of the syringe being driven automatically (tactile aid) in order to reproduce trajectories inserted by experienced instructors. Thus, the student can feel as if the instructor was conducting the learner's hand while guiding her or him.

As dentistry is a skilled profession, tactile skills of a dentist play an obvious role in delivering dental treatment to the patients. One of the current trends in dental education is to empower dental students on a global platform using advanced technology. The technology of haptic is known to provide a unique experience of a sense of touch either as tactile or kinesthetic to the user. The force feedback system in a haptic device can offer "a clinician in training" to feel the "tissues" during pre-clinical procedures before working on real patients. This paper focuses on how virtual simulators with haptic technology can play a role in bridging the gap in dental education.

Training invasive medical procedures at the pre-clinical development is a considerable educational challenge. The traditional approach, with animals and corpses, presents both ethical and practical issues. So, the use of virtual reality (VR), which enables low-cost realistic simulations, repeatability and real time feedback, is a promising solution. Such ascertainment motivated the development of the virtual environment VIDA Odonto, which resorts to VR technologies, realistic modeling of patient and tridimensional immersive interaction. The developed prototype of the virtual environment of such system was tested and evaluated by professionals with clinical experience and beginners, demonstrating its viability to be a relevant educational resource in dentistry courses.

Aim: to evaluate the use of anatomical models for administration of anaesthesia techniques compared traditional lecture among dental students. Materials and Methods: Group A comprising of twenty five students were made to listen to videos on administration of local anaesthesia and group B consisting of another twenty five students received only lectures on administration of local anaesthesia. Both the groups were assessed by a questionnaire at the end of the section. Statistical analysis was done by using cronbach'salpha, which assesss the reliability between two groups. Results: Group A students were more confident in locating the anaesthetic sites than Group B students. Pass rate and mean value of Group A students was high when compared with Group B .Moreover there was significant variation in anxiety levels between the two groups. Conclusion: This method helps the students to recognise the importance anatomy for learning anaesthetic techniques and also increased patient's safety during first injection.

Resumo
Training invasive medical procedures at the pre-clinical development is a considerable educational challenge. The traditional approach, with animals and corpses, presents both ethical and practical issues. So, the use of virtual reality (VR), which enables low cost realistic simulations, repeatability and real time feedback, is a promising solution. Such ascertainment motivated the development of the virtual environment VIDA Odonto, which resorts to VR technologies, realistic modeling of patient and tridimensional immersive interaction. The developed prototype was tested and evaluated by professionals with clinical experience and beginners, demonstrating its viability to be a relevant educational resource in dentistry courses.
Although medical simulators have benefited from the use of haptics and virtual reality (VR) for decades, the former has become the bottleneck in producing a low-cost, compact, and accurate training experience. This is particularly the case for the inferior alveolar nerve block (IANB) procedure in dentistry, which is one of the most difficult motor skills to acquire. As existing works are still oversimplified or overcomplicated for practical deployment, we introduce an origami-based haptic syringe interface for IANB local anesthesia training. By harnessing the versatile mechanical tunability of the Kresling origami pattern, our interface simulated the tactile experience of the plunger while injecting the anesthetic solution. We present the design, development, and characterization process, as well as a preliminary usability study. The force profile generated by the syringe interface is perceptually similar with that of the Carpule syringe. The usability study suggests that the haptic syringe significantly improves the IANB training simulation and its potential to be utilized in several other medical training/simulation applications.
