question 51
what is the surface of the tooth that faces or touches the tongue?
mesial
buccal
occlusal
lingual

Explanation:

To solve this, we analyze each option:

• Mesial: The surface of a tooth adjacent to the midline of the dental arch (not related to the tongue).
• Buccal: The surface of a tooth facing the cheek (not the tongue).
• Occlusal: The chewing surface of posterior teeth (not related to the tongue).
• Lingual: The term "lingual" is derived from "lingua" (Latin for tongue), so it refers to the surface of a tooth that faces or touches the tongue.

Answer:

D. Lingual
