  • Patent number: 10321975
    Abstract: A method for continuously evaluating the effectiveness of debridement of a root canal of a tooth, the tooth having an open access cavity and an apex end, includes delivering a fluid to the open access cavity of the tooth, evacuating the fluid near the apex end of the tooth such that the fluid flushes most of the root canal before being evacuated, and continuously evaluating the evacuated fluid for at least one of a presence of debris, a concentration level of the debris, or a type of the debris. An apparatus for use in debriding a root canal of a tooth includes a microcannula or a macrocannula configured to evacuate a fluid in the root canal, and a sensing mechanism fluidically coupled to the microcannula or the macrocannula, the sensing mechanism configured to continuously sense debris in the evacuated fluid in real time.

  • Patent number: 10235861
    Abstract: A mobile device that includes an input device, an output device, and an electronic processor connected to the input device and the output device. The electronic processor is configured to receive, from the input device, information about a disinfectant and set a threshold time, a threshold activity level, or both the threshold time and the threshold activity level based on the information about the disinfectant. The electronic processor is also configured to track a passage of time, an activity level, or both. If the passage of time is greater than or equal to the threshold time, the activity level is greater than or equal to the threshold activity level, or both then the electronic processor is configured to output a user notification, via the output device.

  • Publication number: 20180044615
    Abstract: Stabilized hydrogen peroxide-containing compositions and methods of making same are disclosed. The compositions contain a stabilizer system made up of a disulfonate surfactant, a diester solvent, and a sulfonic acid or a salt thereof in a sufficient quantity to provide the stabilized hydrogen peroxide with an acidic pH value. The compositions are suitable for use as disinfectants, as cleaning agents, and in various personal care applications such as hair care and tooth whitening.
