Periodontal Disease and Mineral Composition of Saliva among Adolescents in the Nenets Autonomous District

Periodontal diseases are among the most common dental pathologies in the world. Studying the composition of saliva can help with early diagnosis of periodontal diseases. Aim: To study associations between periodontal disease (PD) and mineral composition of saliva among adolescents in the Arctic. A total of 171 15–17-year-old adolescents participated in a cross-sectional study based on the method-ology of the World Health Organization. Prevalence ratios (PR) were used as measures of association. Higher concentration of Na was associated with bleeding (OR = 2.01, p = 0.053). Higher Mg content in saliva was significantly associated with fewer sextants with bleeding (PR = 0.39, p = 0.041), calculus (OR = 0.46, p = 0.005) and with PD (OR = 0.46, p = 0.001). The high amount of P was significantly associated with more sextants with calculus (OR = 2.16, p = 0.013). Saliva ionomics is currently gain-ing an increasing importance due to its simple implementation, non-invasiveness and significant poten-tial for early diagnosis and prediction of the course of PD among adolescents.
