Abstract: A tongue hygiene device to be used with a mildly abrasive cleanser, the tongue hygiene device having a generally elongate handle section and a generally disk-shaped cleansing section. The handle section is ergonomically designed to allow the user to effectively and comfortably hold the tongue hygiene device in proper cleansing alignment with the tongue. The cleansing section includes three generally parallel, circular patterns of medium-length bristles of medium stiffness, protruding from a generally disk-shaped cleansing head, the cleansing head having a top face, and a bottom face from which the bristles protrude, and a large aperture extending between the centers of the bottom and top faces which is surrounded by the bristles on the bottom face. The bristles allow the tongue hygiene device to cleanse the tongue by brushing bacteria and food buildup from the tongue using a mildly abrasive cleanser.

Abstract: A tooth shade guide casting form for in-office preparation of shade samples of tooth color restoration material (TCRM) to be utilized by dentists in the restoration of a patient's tooth surface. The invention includes a handle, preferably of thin transparent plastic, and a detachable bowl disposed from one end of the handle. The bowl is preferrably the size and shape of a human tooth and is adapted to receive a quantity of photocurable TCRM to be hardened therein. After hardening, the bowl is detached from the handle, leaving the cured TCRM shade sample attached to the first end of the handle. Such samples, having the contour of the bowl, are then used by dentists in selecting the properly colored TCRM for restoring patients' teeth.
