A new periodontal probe—Electro-Perio Probe—has been devised by J. Morita Co. for the measurement of periodontal depth. This new device features automatical digital display and printout of the pocket depth by simply inserting the probe tip into periodontal pocket. As a natural consequence, fast, easy and unpre-cendented accurate measurement is feasible and the error in measurements can be minimized compared with any other periodontal probe.
