Abstract: The device includes a wedge piece constructed for use in the non-surgical treatment of interproximal dental caries. A plunger is provided for driving substances through a passage in or on the wedge piece for enabling the delivery, to the site a carious lesion, of SDF or another substance that is effective for directly or indirectly killing, or biologically damaging, carious bacteria.

Abstract: The device includes a shim component constructed for use in the non-surgical treatment of interproximal carious dental lesions. A plunger may be provided for driving substances through a tube-like channel or bore in the shim component, or an electromagnetic energy-transmissive material may fill the channel, in either case for delivering to the site of the lesion a medium that is effective for directly or indirectly killing, or biologically damaging, the carious bacteria.

Abstract: A Gingival cord-packing instrument has an elongate handle, and opposite end sections for engaging the gingival cord. At least one of the end sections of the instrument constitutes a blade that is so dimensioned and configured as to enable gentle displacement of the gingiva from the adjacent tooth, for effective insertion of the cord. The end sections of the instrument will generally extend in opposite direction and in mutually parallel planes, lying obliquely to the handle axis, with the blades being so oriented as to cause grooves formed in their tip elements to extend in mutually perpendicular planes.

Abstract: Transfer of substances through the skin at a treatment site is promoted by the combined effects of ultrasonic energy and positive and negative pressure. A device having a cup-shaped body is pressed against the skin; the treating substance is supplied to an interior chamber of the body, and is subjected to pressure and ultrasonic vibrational energy therewithin, while a vacuum is drawn thereabout through a surrounding annular chamber.

Abstract: A prosthetic dental device, adapted for percutaneous implantation, consists of a metal core that is directly coated with a first layer of polymer, and is overcoated with a second polymeric layer in which fibrils of a biopolymer are embedded and secured. The fibril nap provides a framework for the growth and attachment of regenerating recipient connective tissue, and also serves as a barrier against epithelial invasion, which would otherwise tend to cause implant rejection.
