ABSTRACT
This work show the levels of the salivary secretion volume in 5 min., the salivary amylase concentration in U/ml and the salivary amylase secretion in U/kg/5 min. in 10 children at 4, 15, 30, 45, 60, 90, 120, 150, 180 days of life and at 9 and 12 months. All the children had the same nourishment orientation and showed a good weight and neuromotor development during the period of the observation. The datas were compared with datas of 18 children with 20-36 months of age and 18 healthy young man. It was standardized the technic and the time-table to collect the salivary secretion. It was observed that the salivary secretion is higher between 90 and 180 days of age preceding theeth eruption. At 12 months of life the levels of the amylase salivary concentration reach the levels of infants and adults. The salivary amylase secretion is high after the 60 days of life. Probably this is responsible by the good starch tolerance at this time.
