    摘要： A system for detecting blood in an oral cavity during toothbrushing. The system may include a toothbrush having a sensor that is configured to emit first light at a first wavelength and second light at a second wavelength, receive reflected portions of the first and second light, and generate a first signal indicative of a first intensity of the reflected portion of the first light and a second signal indicative of a second intensity of the reflected portion of the second light. The system may include a processor operably coupled to the sensor, the processor being configured to receive the first and second signals and calculate a ratio of the first intensity to the second intensity to determine whether hemoglobin/blood is present in the oral cavity. The processor may be a part of the toothbrush or a part of a portable electronic device such as a smart phone.

    摘要： The disclosure provides an improved synthesis for a zinc-lysine complex having the formula [Zn(C6H14N2O2)2Cl]+Cl−, in which a zinc compound selected from ZnO and ZnCl2, is reacted with a lysine compound selected from lysine and lysine.HCl, in aqueous acid. The disclosure also provides oral care and personal care compositions comprising the complex prepared by the synthesis, and methods of using these complexes and compositions.
