Colorvue Perioscreen Probes Easy to read, ergonomically designed, eco-friendly. Hu-Friedy’s Colorvue Perioscreen probe provides a fast and easy-to-use method of screening periodontal pocket depth prior to definitive probing. The universally colourcoding of green and red indicates absence or presence of periodontal disease. The Colorvue Perioscreen features a metal handle that is not only more ergonomic, but can be reused or recycled.
