1986 • UNIVERSITY OF NORTH CAROLINA • UNC PROBE
Periodontal probes have undergone extensive changes since their introduction by G.V. Black. Since then, these instruments have evolved from a unidimensional, first-generation manual probe into more sophisticated computerized devices. In an effort to increase accuracy and reproducibility of readings and to improve efficiency, the Michigan “O” probe was created by Sigurd P. Ramfjord, followed by other types of calibrated periodontal probes likeWilliams, Marquis, WHO, Goldman-Fox, Narber’s Furcation, Novatech and more. Periodontal probes are used to assess the health of the periodontium for screening purposes or to evaluate periodontal changes throughout a treatment process. TheWHO (World Health Organization) probe that was designed in 1978, may be the correct instrument to use for screening patients in a general practice, but would be less useful when evaluating changes in the periodontal status during active periodontal therapy. Each probe has features that make it unique, and in some cases, specific and limited in use. For probing depth measurements, recessions and clinical attachment levels using a probe with precise millimeter markings increases accuracy and support calibration. This design originates from the University of North Carolina and was initially requested for research purposes. Today, Hu-Friedy®’s PCP-UNC15 is the most sold instrument in Europe and the Middle East.
