The Diagnostic North Carolina Probe is a precision periodontal instrument used to measure pocket depths around teeth during routine dental examination. Also known as the UNC Probe or UNC-15 Probe, it features a thin working tip with clear millimeter markings from 1 to 15 mm for accurate periodontal assessment and charting.

Its slim design helps clinicians examine gingival sulcus and periodontal pockets with better control and access during diagnostic procedures. The clearly marked scale supports consistent readings, making it useful for dentists, periodontists, and hygienists during screening, evaluation, and treatment planning.

This probe is suitable for everyday periodontal use where precise depth measurement is important for monitoring oral health and assessing periodontal condition. It is a practical diagnostic instrument for clinical setups that require reliable probing performance and easy readability.
