초록
이 연구의 목적은 가상현실 시뮬레이션을 이용한 소아환자 치아우식 진단 경험에 대한 설문조사를 통하여, 임상 실습 전 단계의 치의학 전공 학생들을 대상으로 소아치과적 교육에서의 활용 가능성을 평가하는 것이다. 소아 환자 모델로 유치열기의 5세 여아를 개발하였고, 가상현실 속 진단을 위한 치아 우식 모델을 제작하였다. 치의학 전공 학생들은 15분에 걸친 치아 우식 진단 시뮬레이션을 경험한 뒤, 설문지를 통하여 프로그램 사용 경험을 통한 실재감 및 응용 가능성을 평가하였다. 그 결과, 가상실재감과 외양 평가에서 높은 점수를 얻었다. 또한, 가상현실을 통한 치아 우식 진단 시뮬레이션은 임상 실습 전, 후의학년, 성별, 가상현실 체험 경험의 유무에 따른 유의미한 차이가 없다는 설문 결과를 얻었다. 이 프로그램을 지속적으로 발전시킨다면, 치의학 교육 분야에 응용 가능성이 높아질 것이다.
Abstract
The purpose of this study was to evaluate the applicability of virtual reality simulation after experience of dental caries diagnosis for dental students before exposing to clinical pediatric practice. A pediatric patient model of a five-year-old child with primary dentition was developed and a caries model that is amenable to VR(virtual reality) diagnosis was organized and set-up. The dental student’s were allowed to use the simulated model for fifteen minutes and their experiences were evaluated using a self-reported questionnaire to evaluate presence and usability of this application. Overall, virtual presence and appearance area of the simulation were highly scored. The result indicates that the VR model has no significant difference from the actual clinical caries regardless of grade of students, gender and VR experience. If the prototype is continuously advanced, its applicability in dental education will increase.
