Background
In the diagnosis and treatment of periodontal disease, dentists often insert probes into the gingival sulcus or periodontal pocket surrounding the tooth in an attempt to determine the depth of the periodontal pocket. Traditionally, the depth is determined by the dentist's mechanical sense when the probe tip contacts the bottom wall surface of the pocket. In fact, when the tissue is diseased, it may be most difficult to determine a specific depth of the periodontal pocket and the bottom of the wall surface. Healthy gums have sufficient collagen tissue on the bottom surface to resist penetration, so depth can be easily determined by mechanical feel. However, in the case of a periodontal pocket containing diseased tissue, the soft tissue may not be resistant to penetration, it may be easily penetrated by the tip of the probe without sufficient mechanical feel to enable the dentist to determine the depth of the periodontal pocket. It is therefore most desirable to have an apparatus and method by which a dentist or other inspector can accurately determine the depth of a periodontal pocket in a patient's mouth. However, when using periodontal probes, doctors cannot accurately detect whether periodontal has problems because the force is not well controlled.
