  • immersive game for Dental Anesthesia training with haptic feedback
    International Conference on Computer Graphics and Interactive Techniques, 2019
    Co-Authors: Matheus A. O. Ribeiro, Romero Tori, Allan Amaral Tori, Fatima L S Nunes
    Abstract:

    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.

  • SVR - Visual and Haptic Trajectories Applied to Dental Anesthesia Training: Conceptualization, Implementation and Preliminary Evaluation
    2018 20th Symposium on Virtual and Augmented Reality (SVR), 2018
    Co-Authors: Matheus A. O. Ribeiro, Cleber Gimenez Correa, Fatima L S Nunes
    Abstract:

    The virtual training of procedures in the health area must be effective to contribute to the training of apprentices. Although several approaches use computational mechanisms to aid learning in this type of training, the reproduction of visual trajectories of medical instruments coupled with haptic assistance (tactile) assistance to increase the apprentice’s sensory perception is little explored. This work proposes, implements and evaluates a method to provide visual and haptic assistance in the accomplishment of needle trajectories in a gamified simulator of Dental Anesthesia. The trajectory executed by a specialist is recorded and reconstructed through B-Spline interpolations, to be displayed to the learner. The path is also used to provide haptic forces, through which the device can guide the apprentice’s hand. The efficiency of the trajectory executed by the user is obtained from the proportion of the trajectory of the expert done correctly. Tolerances in the calculation of efficiency can be modified in order to create different training scenarios with different levels of flexibility. An evaluation of the proposed method was conducted with volunteers, indicating that visual and haptic aids contribute to the correct performance of the trajectory and that prolonged training can improve accuracy.

  • SVR - Gamification as a Learning Strategy in a Simulation of Dental Anesthesia
    2017 19th Symposium on Virtual and Augmented Reality (SVR), 2017
    Co-Authors: Matheus A. O. Ribeiro, Cleber Gimenez Correa, Fatima L S Nunes
    Abstract:

    Considering the high failure rate in the procedure of applying Dental Anesthesia, this paper presents the process of gamification of a simulator of this procedure. The objective of this serious game is to promote a more attractive learning strategy that encourages and at the same time evaluates training, reducing risks to patients. For this, it was conducted a literature review about serious games applications related to health care. From these examples, the elements of games that could be added to the current context were highlighted. An analysis of the simulator, describing its most relevant points was performed. Results, as well as discussion of problems, solutions and testing showed that the gamification process was successful and the game can be submitted to the experts evaluation.

  • Virtual Reality simulator for Dental Anesthesia training in the inferior alveolar nerve block
    Journal of Applied Oral Science, 2017
    Co-Authors: Cleber Gimenez Correa, Romero Tori, Maria Aparecida De Andrade Moreira Machado, Edith Ranzini, Fatima L S Nunes
    Abstract:

    Objectives This study shows the development and validation of a Dental Anesthesia-training simulator, specifically for the inferior alveolar nerve block (IANB). The system developed provides the tactile sensation of inserting a real needle in a human patient, using Virtual Reality (VR) techniques and a haptic device that can provide a perceived force feedback in the needle insertion task during the Anesthesia procedure. Material and Methods To simulate a realistic Anesthesia procedure, a Carpule syringe was coupled to a haptic device. The Volere method was used to elicit requirements from users in the Dentistry area; Repeated Measures Two-Way ANOVA (Analysis of Variance), Tukey post-hoc test and averages for the results’ analysis. A questionnaire-based subjective evaluation method was applied to collect information about the simulator, and 26 people participated in the experiments (12 beginners, 12 at intermediate level, and 2 experts). The questionnaire included profile, preferences (number of viewpoints, texture of the objects, and haptic device handler), as well as visual (appearance, scale, and position of objects) and haptic aspects (motion space, tactile sensation, and motion reproduction). Results The visual aspect was considered appropriate and the haptic feedback must be improved, which the users can do by calibrating the virtual tissues’ resistance. The evaluation of visual aspects was influenced by the participants’ experience, according to ANOVA test (F=15.6, p=0.0002, with p

The user preferences were the simulator with two viewpoints, objects with texture based on images and the device with a syringe coupled to it. Conclusion The simulation was considered thoroughly satisfactory for the Anesthesia training, considering the needle insertion task, which includes the correct insertion point and depth, as well as the perception of tissues resistances during the insertion.

  • virtual reality based system for training in Dental Anesthesia
    International Conference on Virtual Augmented and Mixed Reality, 2014
    Co-Authors: Cleber Gimenez Correa, Fatima L S Nunes, Romero Tori
    Abstract:

    This paper presents the development and preliminary evaluation of a Virtual Reality-based system for training in Dental Anesthesia. The development focused the simulation of an Anesthesia procedure task. The evaluation involved graphic and haptic issues and had the presence of experts in the dentistry area. The assessment aimed at attributes that may influence the human-computer interaction, hindering realism, an important challenge in systems of this type. The attributes selected were: the update rate, the appearance of the virtual models and the number of viewpoints of the virtual environment, as well as the characteristics of the haptic device. Despite constraints were found, in the perception of the experts, the system may provide realism and help with the training of certain tasks.

  • ethics rounds death after pediatric Dental Anesthesia an avoidable tragedy
    Pediatrics, 2017
    Co-Authors: Peter Milgrom, Colleen E Huebner, Philip Weinstein, Wylie Burke, Erika Blacksher, John D Lantos
    Abstract:

    Early childhood caries (ECC) is the single most common chronic childhood disease. In the treatment of ECC, children are often given moderate sedation or general Anesthesia. An estimated 100 000 to 250 000 pediatric Dental sedations are performed annually in the United States. The most common medications are benzodiazepines, opioids, local anesthetics, and nitrous oxide. All are associated with serious adverse events, including hypoxemia, respiratory depression, airway obstruction, and death. There is no mandated reporting of adverse events or deaths, so we don’t know how often these occur. In this article, we present a case of a death after Dental Anesthesia and ask experts to speculate on how to improve the quality and safety of both the prevention and treatment of ECC.
