title: The geopathological significance of drinking water on the Great Hungarian Plain.
abstract: The author has stated that the teeth of the population of a village on the Great Hungarian Plain were much better in the last century than now concerning the quality of teeth. The water supply of the village has changed by the turn of the century, as the population began to drink the water of deep wells instead of that of the superficial ones. The relation between the decay of teeth and the change in the quality of drinking water could be detected on the basis of the chemical analysis of the water. The water of the last century contained much more fluoride than the water used at present. It must be pointed out that the change in the quality of drinking water was much more favourable from the point of view of epidemiology.
