Question

A. lingual surface of posterior teeth.
B. occlusal surface of posterior teeth.
C. incisal edges.
D. facial surfaces of teeth.

Answer 1

Abrasion is most commonly seen on the occlusal surface of posterior teeth.

Step-by-step explanation:

Abrasion refers to the wearing away of tooth structure due to mechanical actions such as toothbrushing or grinding. It is most commonly seen on the occlusal surface of posterior teeth. This is because the occlusal surface is subjected to the most force during chewing and grinding of food. The cusps and grooves on these surfaces are more prone to wear and tear.
