Several investigations have demonstrated the adverse effects of the hypovitaminosis A in the stomatological field, characterized by ectomesenehyrnal ceIls atrophy and osteoblastic hyperactivity disordered during the phase of the embryonic development; however, the information is limited to the histological manifestations by deficiency in later stages after birth; keeping in mind that we are a country in development with nutritional problems not resolved. The present study was carried out to establish the morphological changes of the dentoalveolar complex present, after birth, for vitamin A deficiency; for which, we used 20 Holstman rats, of 21 days of age, fed with diet of lacking vitamin A, The control group, in addition received weekly one dosis of 100 U.l. of retinol at last to complete the normal dietetic balance. The histological cuts, of rat incisors with avitaminosis A, colored wi...
