ABSTRACT:
Periodontal analysis apparatus includes a probe member having a tip, a probe housing having a guide channel in which the probe member is disposed for reciprocating movement with the tip of the probe member extending from the channel, force applying means for reciprocating the probe member in the housing, and transducer means in the housing for monitoring motion of the probe member and sensing perturbations in probe motion caused by the CEJ and providing output signals indicative thereof.
