Mandibular central incisor mesial and distal heights of contour are located where? Option 1: On the facial surface Option 2 (Correct Option): On the incisal third of the lingual surface Option 3: At the cervical region of the lingual surface Option 4: At the incisal edge of the facial surface

Answer 1

The mesial and distal heights of contour of the mandibular central incisor are located on the incisal third of the lingual surface, which is the part of the tooth closest to the tongue in its biting surface third.

Step-by-step explanation:

The mandibular central incisor is a tooth located in the lower front of the mouth. In terms of contour, the mesial and distal heights of this tooth are found on the incisal third of the lingual surface. In dentistry, this is the part of the tooth closest to the tongue in its biting surface (incisal) third. It's not located on the facial surface, cervical region of the lingual surface, or the incisal edge of the facial surface.
