Video Demonstration

Introduction: Demonstration of the access cavity preparation procedures to dental students is challenging due to the limited operating field and detailed nature of the procedures. It is especially difficult to visualize how instruments are functioning inside the pulp space. The aim of this study was to develop and compare two different views of video demonstration in teaching access cavity preparation. Materials and Methods: Two videos of access cavity preparation were filmed, showing occlusal view of a whole tooth (WT) and sagittal view of a sectioned tooth (ST). Using quasirandomization, third year dental students (n=57) were divided into two groups to watch either one of the videos. The perception and performance of both groups were compared using Mann-Whitney U test and Fisher exact test. Results: At baseline, group WT (n=29) and group ST (n=28) were not significantly different in terms of operative scores (p=0.330). After watching the videos, the basic understanding of the theories were similar between both groups. However, ST responded more positively towards the helpfulness of the video in visualizing the inner anatomy of the tooth and in implementing the procedures (p<0.05). ST also completed the exercise within a shorter time (p<0.001). Nevertheless, the quality of the prepared access cavities was not significantly different between groups. Conclusion(s): Using sagittal view of sectioned tooth in video demonstration of access cavity preparation can improve students learning and performance speed. We highly recommend showing the sagittal view of sectioned tooth in video demonstration of access cavity preparation.

The availability of datasets comprising of digitized images of human body cross sections (as well as images acquired with other modalities such as CT and MRI) along with the recent advances in fields like graphics, 3D visualization, virtual reality, 2D and 3D image processing and analysis (segmentation, registration, filtering, etc.) have given rise to a broad range of educational, diagnostic and treatment planning applications, such as virtual anatomy and digital atlases, virtual endoscopy, intervention planning etc. This chapter describes efforts towards the creation of the Virtual Dental Patient (VDP) i.e. a 3D face and oral cavity model constructed using human anatomical data that is accompanied by detailed teeth models obtained from digitized cross sections of extracted teeth. VDP can be animated and adapted to the characteristics of a specific patient. Numerous dentistry-related applications can be envisioned for the created VDP model. Here we focus on its use in a virtual tooth drilling system whose aim is to aid dentists, dental students and researchers in getting acquainted with the handling of drilling instruments and the skills and challenges associated with cavity preparation procedures in endodontic therapy. Virtual drilling can be performed within the VDP oral cavity, on 3D volumetric and surface models (meshes) of virtual teeth. The drilling procedure is controlled by the Phantom Desktop (Sensable Technologies Inc., Woburn, MA) force feedback haptic device. The application is a very promising educational and research tool that allows the user to practice in a realistic manner virtual tooth drilling for endodontic treatment cavity preparation and other related tasks.

The paper is regarding the automating of driver’s license testing system and updating the results to the person through website and conjointly through registered email. Usually, while driving test the person who requested for license have to be compelled to show his driving skills ahead of the authorities. The person need to operate the vehicle according to several rules. If he fails, he/she are knocked out and have to appear for the driving test next time. The Officials observe mistakes of the applicant physically. The proposed solution for the automation of existing manual test method permits the elimination of intervention of humans and improves the accuracy of driving test thereby going paperless, with Driving Skill Evaluation System. In the proposed system, we have a tendency of taking data from sensor as inputs from hardware simulator and stores into the database. In this system, the person participating in the test are obsereved by sensors. Therefore weather the person is qualified or not is informed to the applicant as well as the authorities. Gradual increase in number of road hazards are due to less practice in driving and illegal driving license given to the unskilled drivers by taking bribe. To beat this drawback, automated driving license test will be advantageous. This solution is introduced for ensuring the quality in approving in license to enhance safety.

BACKGROUND The current cariology education based on the traditional teaching method faces a lot of challenges. Meanwhile, the COVID-19 pandemic causes an unprecedented disruption in medical education and healthcare systems worldwide. Innovative teaching mode of Cariology education is required to change the situation. OBJECTIVE To evaluate the application effects of a case-based social-media-assisted teaching method in cariology education. METHODS Dental students of Class 2019 and Class 2018 were enrolled into the experimental group and the control group, respectively. A case-based social-media-assisted teaching method was used in the experimental group, which included pre-class activity via social media, additional discussion and practice process record in class, and questions and answers via the platform after class. The traditional teaching method was used in the control group, which was conventional preparation before class, traditional lectures and demonstrations, followed with students practice in class, and questions and answers step after class. The teaching materials were the same in both groups. At the end of the program, students from both groups took cavity preparation skill evaluation tests. Questionnaires were tested on the case-based social-media-assisted teaching group students anonymously. All data were analyzed using the SPSS statistical software. RESULTS The students cavity preparation skill evaluation scores was 82.51±6.82 in the experimental group while 77.19±5.98 in the control group (P<.05). The questionnaire response rate was 100%. Of those, 94.3% of the students recommended the case-based social-media-assisted teaching method in cariology education. The majority of the participants agreed that it helped them memorize the theoretical knowledge of cariology, facilitated in-depth discussion, improved their enthusiasm and initiative in learning, and enhanced the relationship between teachers and students (98.1%). They also recognized that the classroom atmosphere was active (88.7%). CONCLUSIONS The case-based social-media-assisted teaching method was beneficial in terms of learning, as demonstrated by the statistically significant improvement of the cavity preparation skill evaluation scores and satisfaction from attended students. It could be used to supplement the teaching of cariology.

Background: Goal-Oriented Learning (GOL) pedagogy might increase dental students' skill to achieve desired public health goal. Purpose: The objective of this study is to assess the effectiveness of GOL system in terms of increasing knowledge retention as method of curriculum delivery in comparison to traditional lecture method and to explore the perceptions and experiences of students and tutors in regards to GOL system. Method: The study was conducted among all the 2nd  year BDS, Sapporo Dental College using Quasi-Experimental design. Intervention and control group were taught using GOL and lecture based method, respectively. SAQ type questions were used to assess the level of knowledge before and after intervention in both groups. Students and tutors perceptions and experiences were evaluated using modified course experience questionnaire and tutor response questionnaire. Result: Level of good score and mean knowledge score differences between pre-test and post-test were more observed in GOL group. These differences found are statistically significant. Though most of the students of GOL system perceived that it contributes in developing their generic skill like improving problem solving, analytic and expression skill, majority of them reported that workload was heavy on them. Most of students were satisfied relating to tutor role, facilities available and evaluation system in GOL group. Overall satisfactions were superior in GOL groups in comparison to lecture group among both students and tutors. Conclusion: The study showed that GOL system significantly improves knowledge retention in comparison to traditional lecture system. Moreover, majority of students and tutors gave more positive feedback regarding GOL experience and consider it superior than lecture-based system.

Accurate assessment of dental student performance during preclinical operative mannequin courses is an essential milestone within the educational process. Training on novel, multicolored 3D-printed teeth resulted in higher performances of the students in comparison to training on standard, monochromatic plastic teeth. However, low reliability of students’ grading using standard, monochromatic plastic teeth was reported. The aim of this study was to verify whether the use of 3D multicolored teeth can (1) provide better inter- and intra-examiner reliability, and (2) assess the effect of instructors’ experience on their reliability. The novel tooth analogs consisted of digitally planned and 3D-printed plastic teeth containing green, yellow, and red stratifications according to increasing depths of preparation. Thirty-seven dental students performed three Class I preparations on the 3D-printed teeth, and these underwent blind evaluation by two examiners of varied experience at two timepoints. The data were compared with preparations done on conventional (monochromatic) plastic teeth. Results indicated excellent inter-examiner reliability on 3D-printed teeth (0.768 < ICC < 0.929), but only moderate reliability with conventional plastic teeth (0.314 < ICC < 0.672). The examiner having more experience was found to show higher intra-examiner reliability (ICC = 0.716 and 0.612 using 3D-printed teeth and conventional teeth, respectively) than the less experienced examiner (ICC = 0.481 and 0.095 using 3D-printed teeth and conventional teeth, respectively). The novel, multicolored 3D-printed teeth can provide more objective evaluation of cavity preparation compared with conventional plastic teeth.
