Abstract: A dental device includes a housing unit for removably holding sensor film and a tooth clamp disposed on the housing unit. The tooth clamp consists of first and second resilient arcuate bridges. Each of the first and second bridge has a first and second end. The first end of the first bridge and the first end of the second bridge are interconnected to one jaw of a pair of oppositely disposed jaws. The second end of the first bridge and the second end of the second bridge are interconnected to the other jaw of the pair of oppositely disposed jaws. Each of the oppositely disposed jaws includes a gripping plate, an aperture and a tab for engaging a flexible sheet.

Abstract: A periodontal probe instrument for measuring the depth of a periodontal pocket in the gingiva adjacent a tooth includes a probe handle member in which a displacement sensor and a probe element are mounted. The probe element includes an external end and is disposed adjacent and parallel to the displacement sensor. A tip of the displacement sensor is aligned with the external end of the probe element in a first reference position. A pressure transducer is mounted in the handle member for generating a first output signal indicative of the magnitude of the force applied. A displacement transducer is mounted in the handle member for constantly encoding the displacement of the tip of the displacement sensor as it is moved from the first position to a second position to generate a second output signal indicative of the depth of the periodontal pocket.
