Combined effect of trace elements and fluoride on caries: changes over ten years in northwest Ohio (U.S.A.)
M. E. Curzon
Dental caries examinations were carried out in an area of low caries
prevalence, ascribed to a combined effect of fluoride and other trace
elements. Repeat examinations in 1978 on lifelong resident children aged
from 12 to 14 yr showed caries distribution patterns to be essentially the
same as those found in a previous study in 1968. Some changes in DMFS
scores had occurred, which were associated with changes in the strontium
content of the drinking water; low caries levels were significantly
associated with high strontium concentrations.
