Abstract: Introduction The present study aimed to assess environmental health literacy (EHL) among oral healthcare professionals and compare levels between dentists and non-dentist personnel in oral healthcare settings in Saudi Arabia. Methods The study included dentists and non-dentist oral healthcare professionals (academicians, dental assistants, and allied health professionals) recruited using a convenience sampling approach. Data was collected using a structured questionnaire assessing four EHL domains: knowledge, attitude, confidence, and practice, along with demographic and professional characteristics. Responses were recorded on a 5-point Likert scale, and composite scores were calculated, with ≥70% considered a good literacy level. Data was analyzed using R Statistical Software, employing descriptive statistics, chi-square and t-tests, Spearman correlation, and multivariable logistic regression analyses. Results A total of 384 participants were included, of whom 258 were dentists and 126 were non-dentists. The overall literacy mean (SD) scores were comparable between dentists and non-dentists, with no statistically significant difference in overall literacy levels, at 70.5 (15.1) and 73.4 (15.8), respectively ( p = 0.090). However, non-dentists demonstrated significantly higher knowledge scores and a greater proportion of good knowledge levels compared with dentists ( p < 0.05), while no significant differences were observed in attitude, confidence, or practice domains. Significant positive correlations were found among all literacy domains in both groups. Regression analysis showed that among dentists, older age, attendance at environmental health events, and prior training were significantly associated with higher literacy levels, whereas among non-dentists, attendance at scientific events and place of residence were significant predictors. Conclusion Overall, EHL was moderate among oral healthcare professionals, with notable differences in knowledge favoring non-dentists. Strengthening environmental health education and continuing professional development is essential to enhance literacy levels and promote sustainable oral healthcare practices.
