Abstract
Abstract: For the purpose of investigating severe deciduous caries from seroimmunological standpoint, a total of 34 infants ranged in age from 3.4-6.9 years were examined. The subjects, having pulpinfected caries and diseases on root apex but free from any pediatric diseases (henceforth referred to as S group), were subjected to seroimmunological examinations, namely, serum protein and serum immunoglobulin tests, before and after the dental treatment. Infants having no dental caries and physically in good condition (henceforth referred to as C group) were also subjected to immunological examinations, and the results were compared with those of the S group. The following were the results of the investigation.
