摘要： An apparatus that indicates a proximity of a dental instrument in a tooth’s root canal to the canal’s apical foramen while using the dental instrument to perform a dental/medical procedure. The apparatus includes a signal generator that provides divider signal across a first node and a third node, and a reference impedance coupled between the first node and a second node. The second node and third node include configuration for electrically coupling between a tip of the dental instrument and an electrode coupled with a body tissue of the patient, a stimulation signal being defined across the second node and the third node. The apparatus also includes a microprocessor operable to compare the stimulation signal and the divider signal, and generate a proximity signal in response to the comparison, and a proximity indicator that indicates the proximity of the dental instrument to the apical foramen in response to the proximity signal.

摘要： The present invention relates to a dental head unit capable of measuring a root canal length of a patient. The head unit includes a head section having a sleeve rotatably supported therein for detachably holding a cutting tool therein, a neck section extending proximally from the head section and having a proximal end for connecting to a handpiece body, a contact capable of detachably contacting the cutting tool for providing electric connection to the cutting tool when in contact, and a contact holder fixed to a proximal end of the contact and axially slidable with respect to the neck section. The contact holder has a lead attachment to which a lead for electrically connecting the contact to a root canal length measuring device is detachably attached. The present invention also relates to a contact holder assembly including the contact and the contact holder.
