Abstract
Introduction: Previously, we reported that there was a relationship between the anxiety tendency （STAI） and oral wetness of dental hygienist school students in clinical observation practice. However, although there have been reports on the relationship between the STAI and sleep survey （PSQI）, it has not been fully clarified. Therefore, we conducted this research to obtain findings.
Method: 105 students, average age 20.1 years old （18–45 years old）, female, and healthy were targeted. Each test was administered before and after the practice for STAI and before the practice for PSQI. The reference values were set at 48.6 points for trait anxiety, 45.9 points for state anxiety, and 6 points for PSQI. The value above the standard value was set as the high value.
Results: The percentage of students with high trait anxiety was 51.4%, and the percentage of students with high PSQI scores was 61.0%. The correlation between trait anxiety and PSQI scores was r = 0.43 （p < 0.01）.
Discussion: Trait anxiety was associated with insomnia in students. From the above, it is considered necessary to understand and improve PSQI for the group with high trait anxiety before the practice.
