[Quantitative analysis of thirty-one elements in the stained dental fluorosis of enamel].
OBJECTIVE
To study the relationship between concentrations of thirty elements and fluorine element in teeth with stained dental fluorosis from high fluoride water area and teeth from normal fluoride area.


METHODS
The concentration of thirty-one elements in 43 teeth was measured by plasmatron spectrographic analysis and fluoride selective electrode.


RESULTS
1. Content of F, P, Ca, Mn, As, Se, Al, Ti, Mo, B elements in enamel had a direct relationship to severity of enamel staining. 2. Content of Mn, As, Se, Sr, Nb, Ca, P elements were high positively related to content of fluorine in enamel (P < 0.05).


CONCLUSIONS
Mn, As, Se, F content is closely related to the pigment formation in dental fluorosis of enamel.
