Question

Quizplus · Accepted Answer

The proximal surfaces are surfaces that are adjacent to each other.For example,the mesial surface of the second premolar and the distal surface of the first premolar are proximal surfaces.
The labial surface is toward the lips of anterior teeth,and the lingual surface is the surface closest to the tongue on both anterior and posterior teeth.
The incisal surface is the tearing and cutting surface of anterior teeth,whereas the occlusal surface is the chewing surface of posterior teeth.
The palatal surface is the surface closest to the palate on maxillary teeth,also referred to as the lingual surface.The masticatory surface is also called the occlusal surface and is used for chewing.
