What does the term distal refer to in terms of tooth surfaces?

The term "distal" in dental terminology refers to the surface of a tooth that is furthest from the midline of the dental arch. This concept is important for understanding tooth anatomy and identifying the positions and relationships of teeth within the mouth. In a dental context, the midline is an imaginary line running vertically through the center of the face and dividing it into left and right halves.

When assessing the surfaces of teeth, "distal" applies to the side of the tooth that faces away from this midline, allowing dental professionals to communicate effectively about tooth positioning and treatment planning. This term is frequently used in contrast to "mesial," which refers to the surface of a tooth that is closest to the midline. Understanding these terms is crucial for precise communication in dental practice and helps in accurately documenting conditions or treatment approaches.
