Abstract
This work reports on the ages of gingival eruption of deciduous and permanent teeth observed from the time of birth until 30 months old, captive-born individuals.
All of the animals were born with the protrusive di1 already through the gingival border. The dmp4 were the last teeth of the deciduous series which emerged at 24.5±3.11 weeks in the males and 27.8±2.95 weeks in the females.
Significant sexual differences were found between the eruption period of the dpm2, dmp4 (p<0.05), and dpm4 (p<0.01), with the males being more precocious than the females.
The first permanent tooth that emerged, usually, was the M1 at 13.50±2.12 months in the males, and 14.00±0.82 months in the females. At 30 months of age, not one individual had replaced his deciduous canine or premolar teeth with the permanent ones, and, moreover, the M 33 had not yet emerged.
