Página 134 - The cause of the prevalence of dental caries is that the natural foodstuffs are to a large extent ridded of their accompanying fibrous parts and prepared and consumed in a manner which renders them liable to lodge and undergo acid fermentation in the mouth ; while from the same cause and the induced condition the micro-organisms of the mouth lodge, multiply, and augment the rapidity and intensity of the acid fermentation.

However some people who are in the habit of eating strongly acid fruits are particuarly free from caries, as for example the Sicilians, who are large consumers of lemons. Goadby (64) suggests "that the acids (in such cases) may act as a protective by preventing the development of acidforming organisms, or dissolving away the outer layers of the enamel and with it the contained bacteria, secondary dentine occluding the...

After quoting my generalization he Fays "That tmh a factor does occur is certain, but it hardly explains the fact that animals, dogs, cats, monkeys, rabbits, etc., which exhibit no dental caries, are yet found to have food particles frequently lodged between their teeth after a meal, the fibrous matters themselves remaining impacted. Interstitial caries is rare in animals, and yet commonly occurs in man.
