Outline of Final Research Achievements

The purpose of this study was to verify whether basic practice with a dental handpiece-type skill training tool is effective in acquiring skills before actually preparing teeth or artificial teeth. Self-study using this training device was conducted at our college of dentistry for students in the lower grades. We were unable to collect a statistically significant sample size because face-to-face classes were discontinued due to the widespread of COVID-19. With regard to the improved training protocol, three-dimensional manipulation, as in the previous study in which only two-dimensional manipulation was used, there was a tendency for those who met both the conditions of continuous self-study and a high number of self-study sessions to improve their skills. In addition, training using this training tool improved the motivation of students in the lower grades of dental school to learn.

Academic Significance and Societal Importance of the Research Achievements

歯学部教育では、実際に患者の歯を削る技能までを修得させる。過去には抜去歯を用いて訓練してきたが、倫理的・衛生的観点から人工歯に切り替えられてきたものの、コストと場所、時間の制約が大きく、技能修得の障害となっている。本技能訓練具は、安価な消耗品でいつでもどこでも頻度高く訓練を行うことが可能である。これは初学者のみならず、教育コストをかけることが困難な開発途上国においても有効な訓練方法である。
