Posterior teeth have lingual HOC where?

  1. Middle third

  2. Cervical third

  3. Occlusal third

  4. Just above the gum line

The correct answer is: Middle third

Posterior teeth have a lingual height of contour (HOC) in the middle third of the tooth. This means that the thickest part of the lingual (tongue-side) surface of the tooth is located in the middle third. Options B, C, and D are incorrect because they refer to different areas of the tooth that do not correspond to the location of the lingual HOC. The cervical third refers to the part of the tooth near the gum line, the occlusal third refers to the chewing surface, and "just above the gum line" is not a specific location on the tooth.
