Design outcomes

Primary

Measure	Time frame
This study is not clinical treatment. We apply innocuous cold stimulation onto the anterior teeth. We examine pulpal sensationlinguistically and cognitive-neurobiologically.	—

Secondary

Measure	Time frame
(1)After applying temperature-controlled cold water onto enamel surface of intact anterior teeth through each mouth piece, we examine what kind of sensation individual subject perceives. (2)Using fMRA, we cognitive-neurobiologically analyze the activated areas in the brain.	—
