ABSTRACT:
A multi-measurement periodontal probe (5) has a probing portion (7) which utilizes a needle-like tip (8) to determine the depth of a periodontal pocket. The probe additionally has a measurement member (9) extending opposite to the needle-like tip. The measurement member has gradations or other markings for determining the distance between an occlusal tooth surface and the bottom of the periodontal pocket, at the same time that the depth of the periodontal pocket is determined from the gumline. The use of such a probe allows determining whether periodontal disease is progressing while eliminating the bias encountered with changes in the gumline which may occur as a consequence of periodontal disease. Utilizing such a probe assures that accurate readings are taken and improves the accuracy of the diagnosis of periodontal disease.
