Accessory roots are commonly found in which teeth?

Third molars Central incisors Canines First premolars

Correct Answer:

Third molars

Explanation:

Accessory roots are extra root branches that form in addition to the normal root count of a tooth. The third molar shows the greatest variability in root number and shape among permanent teeth, largely because it erupts last and is highly influenced by developmental and evolutionary differences. This makes accessory roots particularly common in third molars, so you’ll often encounter an extra root beyond the usual configuration. In contrast, most other teeth have a consistent, limited number of roots, so accessory roots are much less common there. This variability is why clinicians pay special attention to root anatomy in third molars on radiographs and during procedures.
