“…They cite reports of Jones, Larsen and Pritchard (1933) to the effect that natives of Hawaii on an alkaline diet were free from caries while those on cereal diets became very susceptible. As Koehne and Bunting (1934) state, however, "Jones, Larsen and Pritchard (1933) relate the dissolution of enamel so frequently seen in Hawaiian children and which they call odontoclasia, to present acidosis, but have presented no data on the alkaline reserve values for blood serum in support of their belief." The further conclusion of Grove and Grove that salivary ammonia dissolves mucin and thus keeps it from forming plaques is also open to question.…”
