828 DENTAL CARIES.
given above, combined with a microscopic and chemical examination of
carious tissue and comparative studies of caries of living and dead teeth,
appear to me to furnish a fair solution of the phenomena of dental
caries. That other agents than those of a parasitic nature are also
often concerned there can be no doubt. To say nothing of predispos-
ing causes, an acid reaction of the oral secretions, acid medicines, acid
foods, etc. may give rise to caries at points which otherwise probably
would have escaped.
