Question: 1 / 1775

Which term is used to describe the distance of a tooth from the midline of the dental arch?

Medial

Distal

The term that accurately describes the distance of a tooth from the midline of the dental arch is "distal." In dental terminology, "distal" refers to the surface of the tooth that is farther away from the midline or the center line of the dental arch. This is crucial for understanding tooth positioning and alignment in relation to other teeth.

For example, on a lower jaw, if you're considering the position of a molar, the side of the molar that is further from the center of the mouth is considered distal, while the side that is closer to the midline is termed mesial.

Understanding these positional terms is essential for effective communication in dentistry, as they help clarify the exact location of dental issues or when planning treatments that involve specific areas of the dental arch.
