Outline of Final Research Achievements

Brain activity during listening to dental turbine sounds was investigated using functional magnetic resonance imaging (fMRI) to simulate unpleasant stimuli related to dental treatment and compared with the use of the counting method. The results showed that the brain activity areas stimulated while listening to the dental turbine sound were perceived more exclusively as auditory stimuli with the addition of the counting sound. Therefore, it was suggested that when performing invasive procedures, such as the use of a dental turbine, the counting method externalizes patient awareness and suppresses anxiety.

Academic Significance and Societal Importance of the Research Achievements

歯科臨床において、歯科恐怖症患者への対応は多種多様である。治療中の不快刺激を軽減するための方策としてカウント法が頻用されている。カウント法とは歯科器械に恐怖を感じる者に対して、1から10までの数を数えながら、歯科器械を提示する方法である。患者は、数を数えることで注意が引き付けられ、器械そのものの刺激が減弱すると考えられている。しかし、歯科聴覚刺激に対する脳活動の観点から、その効果を検討した研究はみられない。そこで、歯科治療時の不快な聴覚刺激を聴取中の脳活動をfMRIにて評価することでカウント法の有効性を脳機能の観点から検討した本研究成果には学術的・社会的意義を認める。
