Abstract
Abstract A dental probe is disclosed for use in detecting periodontal disease and gingivitis. The probe includes an elongate member having a distal end with a tapered tip thereon; the distal end has a first portion indicating a non-diseased condition, a second portion indicating a moderately-diseased condition, and a third portion indicating a diseased condition where surgery is required, the first portion being disposed between the tip of the distal end and the second portion, the second portion being disposed between the first portion and the third portion, the third portion being disposed adjacent to the second portion. There is a narrow line defining a boundary between the areas, a first area indicating a diseased condition likely not requiring surgery located between the first portion and the narrow line and a second area indicating a diseased condition likely to require surgery located between the narrow line and the third portion. The invention also includes a method using the periodontal probe for diagnosing periodontal disease and gingivitis.
