Description
Summary:An automated periodontal probe has been developed to measure pocket depth and attachment loss in a single measurement under controlled force conditions. A natural anatomic landmark, the cemento-enamel junction (CEJ), is used as a reference for attachment level measurements. The CEJ is detected automatically by immediate digital postprocessing of simultaneous measurements of probe tip acceleration and displacement during probing. Clinical trials in the beagle dog model for naturally occurring periodontitis have shown that the automated probe, when used with 35 g probing force, has a repeatability of 0.16 mm and a bias of 0.09 mm. These results indicate that the automated periodontal probe is capable of attachment level measurements with a high degree of repeatability and validity.
