In dental anatomy, the furcation refers to which area?

• A. The crown of the tooth
• B. The area where the roots divide in multi-rooted teeth
• C. The root apex
• D. The alveolar process near roots

Answer: (B)

Furcation is the area where the roots divide in multi-rooted teeth. This is the space between the roots where the tooth splits into two or more roots, such as the split between mesial and distal roots on a molar. Clinically, probing this area helps detect furcation involvement, which is important in periodontal assessment. Teeth with a single root don’t have a furcation region. The other options refer to different parts: the crown is the part above the gum, the root apex is the tip of the root, and the alveolar process near roots is the bone surrounding the roots.
