Abstract : The calcification ability of body fluids was measured by the techniques developed for studying remineralization of softened tooth surfaces. Human submaxillary, parotid and whole salivas had marked calcifying properties and individual differences were evident. Human blood serums had considerably less calcification ability and were similar to the extracellular fluid synovial fluid. Some of these serums and synovial fluids had no ability. The method offers a new and unique approach to the direct measurement of the calcifying powers of body fluids and of correlating these properties with pathological conditions affecting calcification processes. The method was used for both in vivo and in vitro work. For the latter, small slabs of softened tooth enamel were inserted subdermally in guinea pigs. After eight days, the slabs were removed and the hardness determined.mExtensive rehardening occurred. This variation of the method should be useful for the vitro controlled experiments with animals, and possibly even humans. (Author)
