Hearing loss and primary tooth defects have been separately associated with neurological impairment, but have not been systematically examined in the same population. To investigate the association of these defects and to explore their potential use as prenatal biological markers, 18 children presenting for hearing evaluation were examined. 11 had enamel defects. 5 had defects consistent with a systemic insult occurring in the 2nd trimester, 2 between 29-33 wks gestation, and 4 near term. Hearing loss was more severe in the 5 with enamel defects occurring in the mid-trimester x=70 dB), than in the 4 subjects with defects occurring around term x=23 dB) (t=3.1; p
