[Prevalence of tongue anomalies in children].

The prevalence of grooved tongue, geographic tongue, and ankyloglossia, was investigated in 660 children, 3 to 13 years old, which attended the Out patient Clinic of the University Hospital of Buenos Aires for unrelated complaints. The figures obtained are at variance--by far--from those published by other people engaged in the same line of research. Probably, further studies with a much larger amount of patients are called for.
