ABSTRACT:
A dental apparatus for measuring the sensitivity of teeth. The apparatus includes an electrode probe for contacting a tooth and an electrical lead for forming a complete circuit with the probe through the tooth. Electrical energy is applied to the tooth in varying amounts; the apparatus measures and records the quantitative magnitude of a parameter proportional to the effective electrical energy applied to the tooth.
