Taste disorder in youth is possibly related to the changes in their lifestyle, such as the reverse of night and day time, population of internet, short sleep, change in eating habit and so on. However, until now, there have been few epidemiological studies regarding the relationship between taste disorder and the changes in life style in youth. We suveyed the prevalence of taste disorder in Japanese youth, and examined to clarify the causes. The subjects of this study were 153 freshmen (first grade students) of Tohoku University Graduate School of Dentistery (male n=103, female n=50), who agreed with our project, aged from 18 to 31 years old (mean=19.4). The gustatory test by means of taste disc method was carried out to them for examining their taste disorder. Gum teste was also carried out for examining their secretory function of the whole saliva. Besides, we asked them detailed questions about their systemic disease, the medication and life styles including eating habit. The result
