摘要： Apparatus and methods for monitoring a tooth may include sensing acoustic energy propagating from regions (such as a root canal system) in and/or near a tooth. The apparatus and methods may be used with root canal cleaning treatments to determine the efficacy of the treatment and/or to reduce risk of post- treatment complications. An acoustic source (e.g., an acoustic transducer and/or a high-speed liquid jet) may be used to transmit energy into a tooth and/or regions near a tooth. An acoustic receiver may be used to detect acoustic signatures of acoustic events (e.g., acoustic echoes and/or acoustic cavitation) occurring in the tooth. The acoustic signatures may be used, for example, to determine the progress of a root canal cleaning treatment and/or the presence or movement of material toward a periapical region of the tooth. Apparatus and methods for monitoring a tooth may include detecting impact of a first jet on a tooth and actuating a second jet in response to detection of the impact.

摘要： Apparatus and methods for root canal treatments are provided. In some embodiments, an aiming element may be used to position a high-velocity liquid jet near a desired location in the tooth. Embodiments of the aiming element may include an interrupter that deflects or impedes the liquid jet when it is not desirable for the jet to propagate from the aiming element. Embodiments of the aiming element may include an elongated member that permits passage of the liquid jet through a channel. The elongated member may include one or more openings, for example, on sides and/or ends of the member. Some root canal cleaning techniques include one or more applications of the liquid jet followed by application of a disinfectant such as. for example, an aqueous solution of sodium hypochlorite.
