Quint (Dental Arch Section)

A quint (dental arch section) is a method of dividing the dental arch into five distinct segments to help clinicians describe the location of teeth, disease, and planned treatments. Unlike the more commonly used quadrant or sextant systems, quint division assigns five zones that can provide an alternative way to group teeth for assessment, charting, and scheduling procedures.

In practice, the precise boundaries and numbering of quints may vary between clinicians and charting systems, so dental teams will clarify which convention they are using when discussing care. The system can be useful for targeting restorative work, periodontal treatment, oral hygiene instruction, and coordinating multi-stage procedures by focusing attention on one specific section of the arch at a time.
