Abstract

A smart toothbrush system, utilizing fluorescence and an intraoral camera, includes a toothbrush handle with embedded electronics, detachable brush and intraoral camera heads, and wireless connectivity capability for communication with external devices. The detachable brush head system is capable of directing particular wavelengths of light to the oral cavity, producing visible fluorescence when incident upon certain biomaterials that are indicative of the presence of various dental conditions. The intraoral camera head is capable of directing the same wavelengths of light to the oral cavity to produce the same fluorescing effect and can be used to closely inspect or record the presence of harmful biomaterials indicative of dental health.
