The COVID-19 Pandemic’s Effect on Dental Students’ Attitude and Habits About Oral Hygiene

ObjectiveThis study aimed to evaluate the oral hygienebehaviors and associated factors, such as COVID-19infection history, vaccination status, smoking habits,and gender, among young adults during the COVID-19pandemic.Material and MethodA cross-sectional survey was conducted with 328participants aged 18–25 years. Data were collectedthrough a structured online questionnaire thatincluded demographic information, smoking behavior,COVID-19 history, and oral hygiene practices.ResultsOf the participants, 56.4% were female, and themean age was 21.74 ± 2.21 years. A majority (87.8%)reported brushing twice daily, while only 30.5%changed their toothbrush after a COVID-19 infection.Smoking was significantly more prevalent amongmales (p < 0.001) and was associated with pooreroral hygiene practices. Dental floss and toothbrushcover usage were higher among females (p < 0.001and p = 0.017, respectively). Participants who hadexperienced COVID-19 were more likely to adopt postinfectiontoothbrush replacement (p < 0.001). Mostparticipants (76.8%) believed that good oral hygienehelps reduce the risk of COVID-19 transmission.ConclusionAlthough oral hygiene awareness was generally highamong young adults during the pandemic, importantbehavioral gaps remain, particularly in post-infectionhygiene practices and among smokers. Genderdifferences in hygiene behavior were notable, withfemales demonstrating more preventive habits.Public health strategies should promote targeted oralhealth education focusing on infection prevention andhygiene reinforcement.
