    • A tooth treatment device includes a detector that detects a marker of oral health and a fluid ejector that ejects fluid against teeth in response to the detected marker. The device can include a housing configured to be held on hand, the fluid ejector being positioned at an end of the housing. The fluid may include a liquid, a medicant, a cleansing solution, cleaning particles, or any combination thereof. The medicant can include any combination of a chelating agent, fluoride, a fluorescent dye, a bacterial specific probe, and a biochemical specific biomarker. Further, the device can include a servo controller controlling pressure of ejected fluid in response to the detected marker and a sensed surface condition, latter including for example, a mechanical property of tissue. The device may include a pressure sensor that senses pressure of the fluid in the ejector. Also included may be a distance sensor that senses distance of the ejector from a tissue surface. The surface condition may be sensed using the sensed pressure, sensed distance, or any combination thereof. In some embodiments, the fluid ejector comprises a stationary magnet assembly providing a magnetic field and a coil assembly, slidably disposed with respect to the magnet assembly, the coil assembly driving ejection of the fluid jet. A method of tooth treatment includes detecting a marker of oral health and controlling ejection of a fluid jet against the tooth responsive to the detected marker. In some embodiments, detecting the marker includes detecting plaque and the ejection is controlled to clean the plaque. Detecting the marker can include collecting a sample from an oral cavity.
    • 牙齿治疗装置包括检测口腔健康的标记物的检测器和响应于检测到的标记物将流体喷射抵靠牙齿的流体喷射器。 该装置可以包括构造成手持的壳体,流体喷射器位于壳体的端部。 流体可以包括液体,药剂,清洁溶液,清洁颗粒或其任何组合。 药物可以包括螯合剂,氟化物,荧光染料,细菌特异性探针和生化特异性生物标志物的任何组合。 此外,该装置可包括响应于检测到的标记物和感测到的表面状况控制喷射流体的压力的伺服控制器,后者包括例如组织的机械特性。 该装置可以包括感测喷射器中的流体的压力的压力传感器。 还包括可以感测喷射器与组织表面的距离的距离传感器。 可以使用感测到的压力,感测距离或其任何组合来感测表面状况。 在一些实施例中,流体喷射器包括提供磁场的固定磁体组件和相对于磁体组件可滑动地设置的线圈组件,线圈组件驱动喷射流体射流。 牙齿治疗的方法包括检测口腔健康的标记物,并响应于检测到的标记物控制针对牙齿的流体射流的喷射。 在一些实施例中,检测标记包括检测斑块,并且控制喷射以清洁斑块。 检测标记可以包括从口腔收集样品。
