Periodontitis was assessed by the community periodontal index (CPI), including clinical attachment loss (CAL) at index teeth. The prevalence of individuals with at least one tooth with periodontal probing depth (PPD) \u2265\u20094\u2009mm was estimated for 16 capitals and CAL \u2265\u20094\u2009mm for the whole country according to age group, sex, dental visit in the previous year and household income.

CAL\u2010estimated prevalence reduction was 51% from 2003 to 2023. The decline in prevalence was stronger and statistically significant among adults of higher income groups for PPD and CAL, indicating increasing relative inequalities in age groups.
