A UNC-15 periodontal probe with a moulded silicone handle. The working end is marked at every millimetre up to 15, with heavier bands at 5, 10 and 15, giving the most detailed pocket reading of any standard probe and making it the usual choice for full periodontal charting. Marked at every millimetre to 15mm with bands at 5, 10 and 15 Millimetre detail suited to full periodontal charting Ergonomic silicone handle reduces pinch force and hand fatigue Hardened Japanese-standard J2 stainless steel working end, autoclavable FAQsWhy choose a UNC-15 over a CP-12?The UNC-15 is marked every millimetre rather than in 3mm bands, so it records pocket depth in finer detail. That matters for full periodontal charting and monitoring change between appointments.Why choose a silicone handle?A moulded silicone handle is wider and lighter than a solid steel one, so it takes less pinch force to control the instrument. Across a full day of appointments that means noticeably less hand fatigue, and the textured surface keeps its grip when wet or gloved.What material is this instrument made from?The working end is hardened Japanese-standard J2 stainless steel, which holds its edge through repeated autoclave cycles, set into a moulded silicone handle. Both are fully autoclavable.Part of our diagnostic range alongside the CP-11, CP-12, CPITN and Nabers furcation probes.Manufactured by InstruDental, UK specialists in dental hand instruments.
