| Sumario: | Chronologic sequences of dental organogenesis rnorphohistochernical characteristicaare described prior to appos:tional stage. They were the following:1) Basal rnernbrane Fuchsin Aldehyde positive ( future arnelo-dentinal junc-tion).2) Increase of cellu1ar layers-in intermediate stratum with metachromasia and alciar:ophilia in stellate reticulum.3) Metachromasia and alcianophilia in papilla with differentiation of basophile odontoblasts on its periphery.4) Alcianophile dentine deposit and PAS + with basophile ameloblasts polarity change and posterior secretion of adamantine matrix sligtly PAS +. Technical oxidai:ion variation with periodic acid during 10', Shiff reactive mbstance 15' and the posterior and inmmediate application of methenamine silver 1 hoUTat 609C allows to identify clearly ~reactive subst::mces to per;odic acid likeglucogene and basal memhrane reactive components |
