Abstract
Real Decreto 140/2003 of February 7, provides the opportunity to request approval of a temporary exception to the parametric value for the parameter B of Annex I, including fluoride.
The work presented aims at testing the effect of water with fluoride levels above the parametric value on the prevalence of caries and dental fluorosis, total and by grade, in the permanent dentition of schoolchildren in 12 years in order to establish the basis for the valuation of non-compliance and health decisions to applications for permits for temporary emergency situations and new parametric value.
Sixty students were explored in a municipality of Tenerife where the concentration of fluoride in the water for human consumption has remained at 2,7 ± 0,5 mg / L, ie around the value ± 0,5 considered adequate to prevent dental caries and minimize the occurrence of dental fluorosis.
The methodology used is standardized by the WHO. The examination included the recording of caries and dental fluorosis measured by the index Thylstrup and Fejerskov (TF).
There was a prevalence of dental caries of 38,33%, with a CAOD 0,87 and 81,67% of dental fluorosis: 35% for TF1-2, a 31,67% for TF3-4 and 15 % for grades TF5-9.
Passing the values established requires the establishment of measures for health protection by restricting the use and consumption of water for children up to 8 years old.
