We developed a portable device (Breathtron™) to measure volatile sulfur compounds (VSC). The aim of this study was to elucidate the circadian changes of VSC using this device. Five male students of Tohoku University Graduate School of Dentistry participated in the experiment; the VSC of the participants was measured for 2 days. VSC levels showed drastic changes according to meals and brushings. VSC level was the highest in the early morning, significantly reduced after meals and gradually increased until next meals. The results of the present study show that circadian changes exist in VSC level.
