Abstract: In dentistry very often soft tissue has to be cut. It has become customary to cut soft tissue, in particular gum or gingiva, or to disinfect pockets in the gingiva that exist at the neck of teeth with the help of laser light. The same applies to a disinfection of the channel in the root of teeth (endodontic treatment). Prior art concepts of cutting soft tissue rely on the use of red or infrared diode lasers and lead to an excessive heating the tissue and damaging of surrounding tissue. We suggest a device for treatment comprising a laser diode with a wavelength of 445±15 nm, in particular 445±10 nm, for providing the laser light. The use of e.g. 445 nm for cutting soft tissues has numerous advantages.

Abstract: The present invention discloses a tool, kit and method for applying loading, torsional/twisting, oscillatory or vibration induced forces to a bond line established between a tooth root surface and an associated bone defined socket within which the tooth is held. Forces are applied typically for a given number of cycles or iterations in order to adequately pre-loosen the tooth from the bone.

The body includes a pair of tooth engaging portions adapted to being inserted into contact with opposite surfaces of the tooth root surface and opposing surfaces associated with the bone receiving socket. The tool introduces loading forces to the engaging portions, causing the tooth to displace within the socket sufficiently to fracture the bond with the bone, thereby facilitating tooth removal.

Abstract: A method for cutting with a tool comprises rotating the tool in a first direction. Then, at a predetermined moment, quit rotating the tool and allow the tool to coast in the first direction. While the tool coasts, a parameter is determined that represents drag experienced by the tool as the tool coasts. If the determined parameter does not exceed a predetermined limit then the tool is rotated in the first direction. If the determined parameter exceeds the predetermined limit, then the tool is rotated in another direction opposite the first direction. The predetermined moment when the tool begins to coast may be any desired moment, such as when the tool rotates through a specific distance or for a specific period of time.
