Enhanced prevalence of ankyloglossia with maternal cocaine use.

A series of 500 term neonates was examined in a well-baby nursery, 68 of whom tested positive for maternal cocaine use. From logistic multiple regression equations, weight and crown-heel length were significantly smaller in the maternal cocaine-use subset of this case-control study. Partial ankyloglossia, with a prevalence of 4.4 percent in the overall series, was significantly more common in males than in females (6.0% versus 2.3%), while race (black or white) had no influence on trait frequency. Controlling for race and sex, ankyloglossia was 3.5 times more likely to occur in the drug-use series, perhaps as a function of diminished mitotic rates.

Natal primary molar: case report.

The case of an immature natal maxillary first primary molar is reported. Natal molars are rare occurrences, the present instance being only the eighteenth reported case. Clinical and histologic examination revealed that the tooth was rootless, incompletely mineralized, and acutely inflamed. Subsequent radiographs showed that the tooth was actually the primary first molar.

Oral anomalies in the neonate, by race and gender, in an urban setting.

A broad range of developmental anomalies and morphologic variants may occur in the oral cavity of the newborn. Because many of these are transient (e.g.: palatal and alveolar cysts, lymphangioma), self-correcting with age, conventional assessments of older children can yield significantly altered trait incidences. A total of 500 normal full-term newborns (blacks and whites) were assessed by standardized criteria for 11 oral conditions, in addition to collating data on maternal conditions (age, gravidity, tobacco and alcohol use). Leukoedema and median alveolar notches were significantly more common in blacks, whereas palatal cysts were 2.5 times as likely to occur in whites. Ankyloglossia, three times as common in males, was the one trait to exhibit a significant predilection by gender. Low maternal age (less than 20 years) significantly enhanced the risk of alveolar lymphangioma in these data.
