Which of the following is a common oral finding in individuals with Down syndrome?

• A. Protruding tongue
• B. Smooth tongue
• C. Short tongue
• D. Flabby tongue

Answer: (A)

A hallmark oral finding in Down syndrome is a tongue that often protrudes from the mouth. This happens because many individuals have macroglossia (an enlarged tongue) along with lower tone in the facial muscles. The combination means the tongue can rest in a forward, protruding position, sometimes more noticeable when the lips don’t seal completely.

Other descriptions like a smooth tongue are less typical, since fissured tongue can occur in Down syndrome and the key feature clinicians notice is the protrusion due to the tongue’s relative size and muscle tone. A short or overly flabby tongue doesn’t capture the most characteristic presentation as well as a protruding tongue does.
