  • Periodontal probe
    Patent number: 5318442
    Abstract: An automated periodontal probe uses a logic device to control the drive motor of a distendable probe rod. The movement of the probe rod is measurable and the force applied to the rod is quantifiable, therefore the device affords exacting repeatability of test procedures on periodontal tissues and permits an accurate survey of the gum pockets which survey may be displayed or recorded. Further the device can be calibrated to cause minimum discomfort to the patient.
