title: Clinical orodental abnormalities in Mexican children.
abstract: A total of 32,022 Mexican children (16,473 boys, 15,549 girls) were examined for several congenital oral and paraoral anomalies. The findings for commissural lip pits (boys 53.1, girls 52.4 per 1000) are less than those reported for adults. This may indicate that pits become accentuated with age. Fordyce granules were seen with a prevalence of 1.2 per 1000. This is in contrast to the reported 85.6% prevalence for the adult population, also possibly reflecting increased manifestation with increased age. Our data for exogenous tooth pigmentation show increased prevalence with age (group I [5 to 10 1/2 years], 9.8%, versus group II [10 1/2 to 14 1/2 years], 12.9%), possibly indicating decrease in attention to oral hygiene. The prevalence of talon cusp was found to be 0.6 per 1000, and for ankyloglossia 8.3 per 1000. Prevalence values for bifid tongue are reported for the first time, indicating one affected per 187 children examined. The prevalence of fissured tongue (15.7%) shows a statistically significant difference between boys (16.8%) and girls (14.5%). The prevalence of geographic tongue (1.9%) shows a marked difference between group I (2.2%) and group II (1.2%).
