Caries may result in (a) impairment of digestive functions, (b) dental granulomas or dental-root cysts, (c) local spread of infection in bone or soft tissues, and (d) secondary infection in other tissues or organs ( focal infection) .
Caries is not a disease to be considered only from its local aspects, but its far-reaching systemic effects should also be ascertained. Basic studies of structure and composition of dental tissues should be furthered; salivary norms and the immune factor in saliva should be determined; and caries should be further classified.

In the Goms-Valley, in the upper part of the mountain district of Valais, the 4000 inhabitants, before the construction of the main street and railway 50-80 years ago, lived an isolated and primitive but healthy life. Today there are complete and caries-free dentitions in the old people in different localities, but the younger generation, and especially the children, show increasing incidence of caries. A study of their living habits and especially of their diet, in comparison with those of 50-80 years ago, demonstrates the deteriorating effects of soft bread made in modern bakeries with imported flour, and of other imported, refined, or canned foods.
