  • virtual reality simulator for dental Anesthesia training in the inferior alveolar nerve block
    Journal of Applied Oral Science, 2017
    Co-Authors: Cleber Gimenez Correa, Maria Aparecida De Andrade Moreira Machado, Edith Ranzini, Romero Tori, 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<0.01). 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.

  • A comparison between topical and retrobulbar Anesthesia in 27-gauge vitrectomy for vitreous floaters: a randomized controlled trial
    BMC ophthalmology, 2018
    Co-Authors: Rui Zhang, Zhong Lin, Qi Hua Liang, Nived Moonasar
    Abstract:

    To compare the safety and efficacy of topical Anesthesia versus retrobulbar Anesthesia in 27-gauge pars plana vitrectomy (PPV) for vitreous floaters. 30 patients with vitreous floaters were randomized into Group T (topical Anesthesia, proparacaine eye drop) and Group R (retrobulbar Anesthesia), and underwent 27-gauge PPV. A 5-point visual analogue pain scale (VAPS) was used to assess patients' pain experience of Anesthesia and surgery Procedure (during surgery, 2 h and 1 day after surgery). The VAPS of Anesthesia Procedure was 1.27 ± 0.59 for patients in Group R, while it was all 0 for patients in Group T (p < 0.001). There was no significant difference for VAPS during surgery (Group T: 1.13 ± 0.74, Group R: 0.67 ± 0.62, p = 0.67), 2 h (Group T: 0.80 ± 1.01, Group R: 0.67 ± 0.62, p = 0.67) and 1 day (Group T: 0.20 ± 0.41, Group R: 0.27 ± 0.46, p = 0.68) after surgery between these two groups. Only one patient (6.7%) in Group T required additional topical Anesthesia during the surgery. Most of the patients reported the pain experience came from initial trocar insertion in both groups. None of the patients required post operative analgesia in both groups. No intraoperative or postoperative complications were noted in both groups. This study suggested that topical Anesthesia is a safe and effective anesthetic approach for patients with floaters who underwent 27-gauge PPV. ClinicalTrials.gov NCT03049163 . Registered 8 February 2017.

    Abstract:

    Review of post-operative morbidity reports for pediatric dental care under general Anesthesia (GA) show great variations. Until now, no morbidity data has been available to estimate the safety of pediatric patients under GA for dental rehabilitation in Saudi Arabia. The purposes of this study were to (1) investigate post-operative complications associated with dental care under GA and (2) correlate morbidity reports with patient's characteristics, dental Procedures, and hospital protocol. Study sample included 90 children attending GA for dental treatment at major governmental hospitals in Jeddah. Data were collected from every patient on three occasions, intra-operatively at the operating room, and post-operatively via phone calls in the first and third days after operation. Results showed that 99% of the children had one or more complaints in the first day in contrast to only 33% in the third day. Inability to eat (86%), sleepiness (71%), and pain (48%) were the most common complaints in the first day, followed by bleeding (40%), drowsiness (39%), sore throat (34%), vomiting (26%), psychological changes (24%), fever (21%), cough (12%), and nausea (8%). A great significant complaints reduction was reported by the third post-operative day. Age, gender, admission type of the patients and GA duration were the factors that showed a significant relationship with post-operative complaints. Post-operative morbidity was common, but mostly of mild severity and limited to the first day. Hospital staff efforts should be directed to control commonly reported postoperative complaints.
