Abstract : Locating apical foramina is essential for determining root canal working lengths in endodontics. The purpose of this study was to evaluate a bio-electronic method of locating the anatomic apical foramina of human teeth by measuring tissue capacitance between the apical foramen and the oral mucosa with an electronic impedance bridge. In six of the seven teeth tested, root canal lengths determined bio-electronically were identical to lengths obtained by direct measurement. It was concluded that the observation of a significant change in capacitance may indicate the position of the electrode tip as it passes through the foramen; and that after further clinical trials, this application of bio-electronics may prove to be a rapid, reliable, and precise method of measuring root canals.
