Abstract
Association between abnormal fetal and maternal conditions and growth of the dentition was demonstrated by gravimetric observations. No retardation in dental growth was demonstrable in relation to cardiac defects (10 cases), but estimates of fetal age from the selected teeth were one wk, low in fetuses with central nervous system defects (10 cases). Delay was significantly greater among 15 cases with maternal histories of preeclampsia and 15 cases with maternal histories of ante-partum hemorrhage, and among 10 cases where the pathological factors were miscellaneous or multiple, fetal dental growth was retarded by an average of 2 wks.
