ANATOMY

Detailed explanation-1: -Incisal: It’s the bitting edge of the anterior surface of the tooth. Lingual: It’s the part of the tooth surface that faces the tongue, and is nearest to the tongue. Occlusal: It’s the chewing surface of posterior teeth .

Detailed explanation-2: -The five tooth surfaces are occlusal (top of the tooth), mesial (front of the tooth), distal (back of the tooth), facial (side of the tooth facing the cheek), and lingual (side of the tooth facing the tongue).

Detailed explanation-3: -The incisal surface is the biting edge on the canines and incisors, near the front of your mouth, while the occlusal is the biting edge, or the top of, your molars and premolars.

Detailed explanation-4: -Occlusal. The occlusal surface is the broad chewing surface found on posterior teeth (bicuspids and molars). The occlusal surface faces toward and contacts the teeth of the opposite jaw.

Detailed explanation-5: -Mesial surface-medial surfaces of the incisors. This surface is located closer to the front of the mouth and midline. Distal surface-the surface located lateral or distal to the midline and closer to the back of the mouth. The mesial and distal surfaces of two adjacent incisors create a contact zone.
