Periowise color-coded probes by Premier Dental are great for full exams or quick screening. The easy-to-read 3mm green tip indicates periodontal health, while the red mark below the tip marks the possibility of periodontal disease at the spot of insertion. Periowise is even safe for checking around implants, and is autoclavable. Periowise should not be used with phenol or alcohol solutions. It is available in 3-5-7-10mm, and 3-6-9-12mm, in terms of color striping. The Periowise UNC 12 has black striping to indicate increments from 1mm to 12mm, for complete periodontal exams.
