Histometric evaluation of dental alveolar repair in malnourished rats in the intrauterine or postnatal phase.

Objective: Nutritional aggravations during pregnancy or during the early stages of postnatal development can impair bone development; thus, we aimed to assess the effects of food restriction on the dental alveolar bone repair process using histometric analysis.

Design: Thirty-six Wistar rats were divided into three groups: (C) 12 pups were obtained from control mothers with food intake at ease; (GR) 12 pups from mothers subjected to 70% food restriction during pregnancy; (PNR) 50% of maternal food restriction during lactation and 50% of restriction for the 12 pups after weaning. At three months of age, the upper right incisor was extracted from the pups.
