[Pulp diseases in the deciduous teeth. I. Histopathological changes (correlation between microscopic picture and clinical diagnosis)].

Clinical and histopathological examinations of 85 deciduous molars from children aged between 2.5 and 8 years show considerable disagreement between the microscopical picture and the clinical diagnosis according to the classification of WILGA. This calls in question the appropriateness of the histopathological classification for clinical diagnosis. For this reason, the present study was undertaken to elaborate a new classification of pulpal affections in the deciduous dentition with special regard to the various clinical pictures.
