Abstract: Students are at a vulnerable age where they will experience a transition period from late adolescence to early adulthood. Individuals who experience stress and depression can increase bad health behaviour, such as irregular brushing of teeth, irregular dental check-ups at the dentist and neglecting oral hygiene. This will cause an increase in plaque accumulation, which is the main cause of periodontal disease, and a decrease in the resistance of the periodontium, which can cause inflammation. This study aims to assess the relationship between academic stress and the occurrence of gingivitis in 2019 FK UMSU students. This research is a cross-sectional study involving 67 students. Subjects were asked to fill out the ESSA questionnaire, and their teeth were examined. The data obtained were analysed using chi-square. From data analysis, it was found that the majority of respondents had the criteria for severe academic stress and mild gingivitis. The p-value obtained is 0.043, which means there is a relationship between academic stress and the occurrence of gingivitis. There is a significant relationship between academic stress and the occurrence of gingivitis in 2019 FK UMSU students.
