Enamel Decalcification by Cereals of Different Geographic Origin

Abstract

SYNOPSIS IN INTERLINGUADECALCIFICATION DE ADAMANTE PER CEREALES DE DIFFERENTE ORIGINES GEOGRAPHIC.—Pro comparer le decalcification de adamante per productos de fermentation ab frumento, mais, avena, e hordeo ab California, Texas, Ohio, Iowa, Saskatchewan, e Ontario, filtratos preparate per quatro horas de incubation a 37 C in diluite saliva esseva testate durante duo horas contra adamante radioactive, e le dissolution esseva mesurate in referentia a cognoscite standards. Le plus raffinate fractiones de cereal rendeva differentias de usque ad 1: 3 inter le regiones geographic in le quantitate de adamante solvite. Nonraffinate specimens rendeva minus marcate differentias. Le differentias revelava nulle correlation con le nitrogeno, le calcium, le phosphoro, le fluoro, o le oligoelementos contenite in le fractiones o con le prevalentia de carie in le regiones del tests.
