What term refers to the arrangement of teeth?

• A. Dentition
• B. Drift
• C. Diastema
• D. Archform

Answer: (A)

Dentition refers to the arrangement and organization of teeth in the mouth, covering both the upper and lower arches and including the full sets (primary and permanent) and how those teeth are positioned. It describes how many teeth there are, their types, and their alignment within the arches. The other terms describe more specific ideas: drift is the movement of teeth within the jaw; diastema is a gap between teeth; archform refers to the overall shape or outline of the dental arches, not the arrangement of the teeth themselves. So dentition is the best fit for the concept of how teeth are arranged in the mouth.
