Which term is elevation or lump on the bone?

• A. Torus
• B. Sextant
• C. Interim denture
• D. Root canal

Answer: (A)

A torus describes a benign bony outgrowth, an elevation or lump on the jawbone or palate. It’s a localized thickening of cortical bone that most often appears at the midline of the hard palate (palatal torus) or on the lingual surface of the mandible (mandibular torus). It’s typically asymptomatic and found incidentally on exam, which is why this term best fits the description of a bone elevation. The other terms refer to different dental concepts: a division of the dental arch for charting, a temporary denture, and a procedure to treat tooth pulp, none of which describe a bone lump.
