MICROANATOMY

Detailed explanation-1: -Mesial – The surface that is closest to the midline of the face. Occlusal– The chewing surface of posterior teeth . Proximal – Tooth surfaces that are next to each other (i.e., distal of lateral incisor and mesial of canine).

Detailed explanation-2: -The surface of a tooth that is facing an adjacent tooth is referred to as a proximal surface. The area of the tooth that contacts the adjacent tooth is called the contact area [1]. In order to determine which proximal surface is being described, imagine a vertical line drawn down the center of the face.

Detailed explanation-3: -Proximal and distal: These two terms are almost always used in reference to relative locations of parts or places on the limbs. Proximal then refers to something closer to the torso while distal refers to parts and places away from the torso.

Detailed explanation-4: -Distal: On the opposite side of the mesial surface lies the distal surface. The distal surface is the surface farthest from the face’s midline. Proximal: The proximal surfaces are tooth surfaces that are next to each other.
