Fluorosis & Race

Post by admin »

REFERENCE SET: FLUOROSIS IN THE BLACK POPULATION

©2004 PFPC

If fluorides indeed function as anti-thyroid agents, the effects of fluoride, such as 'dental fluorosis' and thyroid dysfunction, should be more observable in Black children than in white children. This is because Black individuals generally have a considerably lower 'normal thyroid status,' making the effects more pronounced in the Black population (see: Long et al., 1985; Schectman et al., 1991, etc.).

This is indeed the case.

In 1962 Russel reported on the progress in Grand Rapids, after 16 years of fluoridation. There was fluorosis in 19.3% of white children, and 40.2 percent of black children.

In 1949, Hurme had also observed more enamel opacities in the upper incisors of black children.

Of course, this has been observed many more times since (Butler, 1985; Duncan et al, 1988; Silberman et al, 1991; Kumar 1999; etc.)
