*2.2. Statistical Methods*

The prevalence of dental caries (DMFT/dmft Index), oral mucosa lesions, and gingival health status (CPI) was obtained using means ± standard deviation and percentages. The calculation was performed according to country of origin, age group, and sex. The one-way ANOVA test was performed to analyse the correlation between the educational level and the clinical parameters (DMFT/dmft Index and CPI).
