Abstract

Abstract

Objective This study seeks to understand the prevalence of dental fluorosis in children residing in ethnic minority areas of Gansu Province and to explore the risk factors of dental fluorosis. Methods Between June and November 2019, 1 344 students from eight ethnic minority counties in Gansu Province were included using the stratified cluster random sampling method. These participants underwent data collection, dental fluorosis diagnosis and fluoride detection in urine samples. Results The prevalence of dental fluorosis among children aged 8-12 years in minority areas of Gansu Province was 29.1%, with a geometric mean urinary fluoride concentration of 1.02 mg/L. Living in the areas of Aksai (OR=2.625, 95% CI: 1.530-4.597, P=0.001), Sunan (OR=2.421, 95% CI: 1.411-4.154, P=0.001), Tianzhu (OR=2.813, 95% CI: 1.599-4.946, P < 0.001) and Xiahe (OR=1.719, 95% CI: 1.022-2.892, P=0.041) counties, having tea-drinking habits (OR=1.508, 95% CI: 1.072-2.120, P=0.018), older age (8-12 years old)(OR = 1.122, 95% CI: 1.021-1.233, P=0.017) and high urinary fluoride concentration (0.10-5.87 mg/L)(OR=1.549, 95% CI: 1.223-1.962, P < 0.001) were risk factors affecting the prevalence of dental fluorosis in children. Conclusions The prevalence of dental fluorosis among children is high in ethnic minority areas of Gansu Province. The factors such as region, tea-drinking habits, age, and urinary fluoride can affect the prevalence of dental fluorosis. Continuous prevention and treatment of tea-drinking type dental fluorosis should be carried out in a targeted manner.
