Tooth Calcification in Low-Weight Human Fetuses
Tooth calcification begins during the intrauterine life and is related to the nutritional status of fetus. The purpose of this study was to evaluate the dental calcification status of 15 low-weight human fetuses aged from the 14th to 28th weeks of intrauterine life through radiographic analyses and...

Tooth calcification begins during the intrauterine life and is related to the nutritional status of fetus.
