Abstract: A method and apparatus for the concurrent treatment of multiple oral diseases and defects while promoting general oral hygiene utilizing electricity are provided for non-human animals. Electrodes are used to deliver an electrical current to the gingival tissues of a mouth in order to achieve a number of therapeutic, prophylactic, and regenerative benefits. These benefits include killing oral microbes, increasing oral vasodilation, reducing oral biofilm, improving oral blood circulation, reversing oral bone resorption, promoting oral osteogenesis, treating gum recession, and fostering gingival regeneration. Other benefits include the treatment of gingivitis, periodontitis, and oral malodor, and other systemic diseases correlated with oral pathogens.

Abstract: A dental system including a computer and a display, and one or more dental sensors communicating with the computer. Some of the dental sensors could be operative to provide information or an image of one or more oral components and communicate the image to the computer or computer memory. The image stored in the memory could be a graphic image and the information could also include an image and a predetermined dental treatment protocol. It could be an X-ray image, a two-dimensional image, a three-dimensional image, a panoramic image, and a CT image. This superimposed dental image, received from a number of dental sensors, and the dental instrument image facilitates correction of errors and inaccuracies in instrument location and/or angle of dental instrument positioning and tooth penetration as well as various measurements such as number and length of root canals and other parameters required for performing an accurate dental procedure.

Abstract: A hand-held intra-oral dental device and method are described for the detection of pre-caries lesions and the prediction of evolution and prognosis of same. The present invention has as its foundation a low-cost tool for predicting the likelihood of the development of Early Childhood Caries (ECC), in contrast to other techniques and associated devices, where their focus is to identify individual pre-caries lesions. This method focuses on the detection of caries precursors or of their patterns and the relationship of those precursors and patterns to the likelihood of subsequent dental disease. The implications for the establishment for early preventive treatment are profound, namely the earliest implementation of preventative therapy for our approach relative to that of the other approaches.

Abstract: An apical position detector for use in dental endodontics includes an electronic controller coupled to a conductive probe and a lip electrode. The probe is positioned in a root canal and the lip electrode contacts another location on the patient's body. The controller produces a test signal as a combination of signals at selected frequencies. The controller then monitors a voltage of the probe and extracts the amplitude and phase of each of the frequency components of the voltage at the probe. Test scores are generated from summations of the amplitudes and/or phases of the various frequency components to determine when the impedance between the probe and the lip electrode changes from a primarily reactive impedance to a primarily resistive impedance. A first test score is displayed to indicate when the impedance changes from a reactive to a resistive impedance. The second test score indicates when the measurement conditions are unsatisfactory. The test scores are displayed in bar graph or similar form.

Abstract: There is disclosed a device for detecting the position of an apical foramen of a tooth's root by measuring a change in the impedance between a measuring needle inserted into a tooth's root canal and an electrode abutting on oral mucosa. This device includes a circuit for generating two kinds of different frequency signals, detection circuits for detecting a change in the impedance in response to the respective frequencies and a "difference" detection circuit for successively comparing outputs of the detection circuits and for producing a "difference" signal, and a feed back circuit for feeding an output of the "difference" detection circuit to one of the input terminals of the "difference" detection circuit so as to equalize its two inputs by addition or by subtraction and thereby to make its output equal to zero. Furthermore, the device is provided with a means for announcing that the output of the "difference" detection circuit is set to zero, and an indicating means for informing that the output of the "difference" detection circuit has reached the specified value when the measuring needle is inserted further into the tooth' s root canal after the above-mentioned zero setting. The position of the apical foramen is considered to be the location of the measuring needle's tip when the output of the "different" detection circuit reaches the specified value.

Abstract: An apparatus for diagnosing the environmental tissue of teeth, which has an electro-mechanical oscillation converter for converting the electric oscillation output from an electric oscillation output generation circuit into mechanical oscillation, a probe connected to the converter to be brought into contact with a patient's tooth for applying the mechanical oscillation from the converter to the tooth, and patient's responding means for actuation by the patient when he detects the sense threshold of the mechanical oscillation applied through the probe to the patient's tooth. Thus, a dentist can scientifically diagnose the health of the tissue of the patient's teeth as distinguished from the diseased part without visual examination nor palpation by the dentist.

Abstract: A system for testing the dental pulp of a tooth by electrically stimulating the pulp with a pulsating signal having a continuously increasing amplitude. The system includes a probe having an electrode adapted to the tooth, and a contact device for sensing when the probe electrode makes contact with the tooth and for increasing the amplitude of the stimulus from an initial value. The intensity continues to increase as long as the probe electrode is in contact with the tooth. The electrical stimulus may be generated by a voltage controlled pulse generator driving the primary of a transformer, with the secondary of the transformer connected to the electrode probe. The transformer has a relatively low cutoff frequency so that the amplitude of the signal across the secondary is proportional to the pulse width of the incoming signal. Consequently, as the control voltage to the voltage control pulse generator increases, the amplitude of the pulses across the secondary also increases. The voltage control pulse generator also drives a counter, and the output of the counter is indicated on a digital display. Since the amplitude of the control voltage is a function of the number of pulses generated by the pulse generator, the output of the counter indicates the amplitude of the electrical stimulus. Alternatively, a ramp generator is connected to one end of the primary and the other end of the primary is periodically grounded responsive to fixed frequency, fixed duration pulses from the output of an oscillator.
