The Nabers furcation probe is specifically used to assess furcation involvement in which teeth?

• A. Maxillary anterior teeth
• B. Mandibular anterior teeth
• C. Single-rooted teeth
• D. Multirooted teeth

Answer: (D)

The Nabers furcation probe is designed to evaluate furcation involvement, which occurs in the space between the roots of multirooted teeth. Its curved, slender tip is made to reach into the buccal and lingual furcations to feel how far bone loss has extended into that space. Since only multirooted teeth (like molars) have a true furcation between roots, this instrument is ideally used there. Single-rooted teeth, such as most anterior teeth, do not have a furcation area to probe, so the Nabers probe isn’t needed for them. In short, it’s specifically for assessing furcation involvement in multirooted teeth.
