A Periodontal William's Probe is a dental instrument used to measure the depth of periodontal pockets and assess gum health. The color-coded version of this probe is designed to make it easier for dentists and hygienists to quickly identify specific measurements during periodontal examinations. Features of a Color-Coded William's Probe: Markings: It typically has markings at specific millimeter intervals, such as: 1 mm 2 mm 3 mm 5 mm 7 mm 8 mm 9 mm 10 mm Note: The 4 mm and 6 mm markings are omitted for clarity and to avoid crowding. Color Coding: The markings are often color-coded for better visibility, especially in low-light or challenging oral environments. The color blocks help clinicians identify depths more easily without squinting or misreading. Material: Made of stainless steel or plastic for durability and ease of sterilization. The color coding is typically embedded or etched to ensure it lasts through repeated use and sterilization. Purpose: To measure the depth of gum pockets around each tooth. To detect periodontal disease by identifying any abnormal pocket depths (e.g., depths greater than 3 mm may indicate gum disease).
