Radiological signs of a supernumerary tooth include which of the following?

• A. Altered shape and size of a tooth bud
• B. Aberrant position of a tooth bud
• C. Different degree of root development of a tooth bud
• D. Presence of more than the normal number of tooth buds

Answer: (D)

Supernumerary teeth come from an extra tooth bud forming in addition to the normal dentition. On radiographs, the most specific sign is seeing more than the normal number of tooth buds or tooth germs, indicating an extra tooth is present. Other features like altered shape and size of a tooth bud, aberrant position, or differing degrees of root development describe variations in a single tooth’s development or eruption but do not by themselves prove the existence of an extra tooth. So, the presence of more than the normal number of tooth buds is the best indicator.
