The Impact of the COVID-19 Pandemic Caused by SARS-CoV-2 on Hygiene, Health, and Dietary Habits: A Survey-Based Study

<b>Background:</b> The COVID-19 pandemic significantly disrupted various aspects of daily life, including hygiene routines, dietary habits, and access to dental care. This study aimed to evaluate the impact of the pandemic on the oral health-related and dietary behaviors and dietary pattern of patients from the West Pomeranian region of Poland. <b>Methods:</b> A cross-sectional survey was conducted among 100 healthy adult participants from the West Pomeranian region, including patients from the Pomeranian Medical University and private dental practices. A self-administered questionnaire consisting of 43 items was used to assess changes in hygiene, dietary behaviors, and the frequency of dental visits during the pandemic. <b>Results:</b> The majority of respondents were under 30 years of age, with women representing 56% of the sample. Most participants resided in large urban areas with populations exceeding 300,000. During the pandemic, 41% of participants maintained regular dental visits, while 37% reported experiencing dental problems; all those who sought care received appropriate treatment. Nearly half of the respondents had undergone quarantine due to SARS-CoV-2 exposure, and 38% expressed fear of infection. The results revealed a notable decline in preventive dental care during the pandemic: only 41% of participants reported maintaining regular dental check-ups. Additionally, 34% reported increased consumption of snacks, while 25% indicated more frequent alcohol intake. 22% of respondents experienced involuntary teeth clenching during the day, and 13% reported teeth grinding, These findings reflect a negative shift in health behaviors during the COVID-19 period. <b>Conclusions:</b> The pandemic had a substantial adverse effect on oral health behaviors, dietary choices, and the use of dental services. Nevertheless, participants demonstrated awareness of these changes and, following the pandemic, expressed an increased understanding of the importance of regular dental visits. It is necessary to implement preventive measures that increase awareness of the health consequences (such as dental caries and periodontal diseases) in order to reduce the neglect of routine dental check-ups.
