Abstract:
Objective To investigate the status of endemic fluorosis in Boxing County in Shandong Province at present,and to provide the scientific evidence for making strategies in prevention and control.Methods Children aged 8-12 years old and adults above 30 years old were selected from 8 endemic fluorosis villages in 2 fluorosis of children aged 8-12 years old were diagnosed by Dean method and skeletal fluomsis diagnosed by clinic and X-Rays.Results Eight villages in 2 towns were chosen underwent epidemiological investigation.Eight villages had water fluoride content>4.50 mg/L.the highest water fluoride content was 5.78 mg/L.The total rate of dental fluorosis of children aged 8-12 years old WaS 90.70%(195/215),the index of dental fluorosis was 2.15 and the rate of dental damage was 24.65%(53/215).The rate of skeletal fluorosis detected by clinic and X-rays in adults older than 30 years old were 30.71%(78/254)and 16.54%(42/254),respectively.The averaged fuoride level in urine wa8 over 1.50 mg/L in 98.95%(189/191)of children aged 8-12 years old and in 97.92%(235/240)adults older than 30 years old,with the highest respectively being 14.50 mg/L and 17.99 mg/L.Conclusions In Boxing County in Shandong Province,endemic fluorosis is not effectively controlled.So endemic fluorosis control mfist be strengthened.
