Postnatal changes in size, morphology and weight of developing postnatal deciduous anterior teeth.

The present investigation is concerned with the postnatal changes in size, morphology and weight of anterior deciduous teeth (maxillary and mandibular central and lateral incisors and canines) in infants aged 0-46 weeks. Relating tooth weight and height to the age of the infant revealed the time at which each tooth achieves its maximum crown height and root formation begins, the rate of root elongation and, in the case of the canine teeth, the postnatal rate of crown elongation.
