Background: Recently, the number of children seeking dental care for traumatic tooth injuries has increased substantially. Aim: This study was aimed at assessing the prevalence of primary tooth traumatic injuries (PTTI) in the paediatric populace of Ekaterinburg, a large industrial centre of the Russian Federation. Design: Following ethical approval, an epidemiological investigation of primary dentition was conducted, evaluating 1,149 children aged 6-72 months (males 586/1,149, 51 %; females 563/1,149, 49 %). The average age of subjects overall was 43.9±17.7 months (males 45.1±17.9 months; females 42.6±17.4 months). Results: The prevalence of PTTI among paediatric residents of this region was 9.75 %, with uncomplicated crown fracture (36.9 %) as the chief primary dental injury. Dental visits attributable to PTTI were most frequent in the age group of 25-36 months, which clearly constitutes the period of greatest vulnerability. Conclusions: The findings of this study suggest that PTTI is a critical issue in children, requiring programmes that address preventive dental care and adhere to established medical treatment standards.
