Final answer:
A patient with torus palatinus will have a painless bony protuberance on the hard palate, unrelated to tongue surface appearance, split uvula, or lingual frenulum tightness. c. Painless bony protuberance on the hard palate
Step-by-step explanation:
A patient with torus palatinus will have a painless bony protuberance on the hard palate. This condition involves a benign growth that arises from the bone of the hard palate. It is not typically associated with any alteration in the appearance of the tongue, such as a map-like appearance, which refers to a condition known as geographic tongue. Also, torus palatinus is not characterized by a split uvula nor a tight lingual frenulum, which refers to ankyloglossia or 'tongue tie' where the lingual frenulum is too short, potentially affecting speech. c. Painless bony protuberance on the hard palate Torus palatinus is a bony growth or protuberance on the hard palate of the mouth. It is generally painless and harmless. The other options (a, b, and d) do not describe features commonly associated with torus palatinus.
