| Outline of Final Research Achievements |
The present study utilized functional magnetic resonance imaging to assess the relationships between cerebral activation in response to auditory stimuli and levels of dental fear and trait anxiety. We found that activation in the left posterior superior temporal gyrus and bilateral precentral gyri positively correlated with dental fear scores in all participants. In contrast, activation in the right middle temporal gyrus, the left inferior frontal gyrus, and the right insula positively correlated with trait anxiety scores in all participants. This difference in activation may indicate some differential level of processing for both types of anxious behaviors.
