Background: Dietary habits play a crucial role in the development and progression of various oral pathologies, including dental erosion, caries, and inflammatory conditions. The consumption of acidic foods, high sugar intake, and poor nutritional choices can significantly impact oral health, leading to detrimental effects on the hard and soft tissues of the oral cavity. This study aims to explore the association between dietary habits and the prevalence of these oral pathologies among a diverse population.Materials and Methods: A cross-sectional study was conducted with 500 participants aged 18-65 years, randomly selected from urban and rural areas. Participants completed a detailed food frequency questionnaire, which included questions on their daily intake of acidic foods, sugary beverages, and other dietary habits. Clinical examinations were performed to assess the presence of dental erosion, caries, and inflammatory conditions such as gingivitis and periodontitis. Data were analyzed using statistical software, and the correlation between dietary habits and oral pathologies was assessed using Pearson’s correlation coefficient.Results: The study found that 70% of participants with high consumption of acidic foods and beverages exhibited signs of dental erosion. Similarly, 65% of participants with high sugar intake had a higher prevalence of dental caries. Furthermore, inflammatory conditions were more prevalent among individuals with poor overall dietary habits, with a significant correlation (r = 0.52, p < 0.01) between poor diet and gingivitis. The data suggest a strong association between unhealthy dietary habits and the development of oral pathologies.Conclusion: The findings of this study highlight the critical role of dietary habits in the development of oral pathologies. Public health initiatives should focus on promoting healthier eating habits to reduce the risk of erosion, caries, and inflammatory conditions in the population. Future research should explore the impact of specific dietary interventions on oral health outcomes.
