PurposeFear of missing out (FoMO) and internet addiction are significant phenomena in today's digital age. This study aims to explore the relationships between FoMO levels, internet addiction levels, time spent on the internet, and other factors among dental students.MethodsData were collected from 252 dental students, including 127 females. Information gathered included FoMO levels, internet addiction levels, university year, age, time spent on the internet, and income level. Correlation analysis and statistical tests were performed to explore relationships between variables.ResultsDescriptive statistics revealed that the majority of participants were between 21 and 24 years old, with most reporting a middle income. The correlation analysis showed a moderate positive relationship between FoMO and internet addiction (r = 0.356, p < 0.001). Time spent on the internet showed a moderately strong positive correlation with internet addiction levels (r = 0.583) and a moderate correlation with FoMO levels (r = 0.316). Average FoMO and internet addiction levels varied across university years, showing fluctuations without a consistent trend.ConclusionFoMO is positively associated with internet addiction and time spent on the internet, highlighting its potential influence on dental students in the digital age. Addressing FoMO and promoting healthier digital habits may help mitigate internet addiction and excessive internet usage. Further research is needed to explore causal relationships and other influencing factors.
