MICROANATOMY

Detailed explanation-1: -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].

Detailed explanation-2: -Contact areas: the mesial contact is in the incisal third near the mesioincisal angle, while the distal contact is more cervically positioned at the junction between the incisal and middle thirds. Angles: the distoincisal angle is not as sharp as the mesioincisal angle.

Detailed explanation-3: -The anterior portion of molar and premolar crowns and the medial parts of canines and incisors are called the mesial parts of these teeth. The mesial surface of the canine touches the incisor next to it, and the mesial surface of the first molar touches the premolar next to it.
