A dental apparatus is disclosed. The dental apparatus can comprise a pressure wave generator to be disposed at a treatment region of a tooth. The pressure wave generator can include an opening to deliver a flowable filling material to the treatment region. The apparatus can include a reservoir for supplying the filling material to the pressure wave generator. The pressure wave generator can be configured to generate pressure waves through the treatment region to cause the filling material to substantially fill the treatment region.

A system and method for providing variable power is disclosed. The system includes a power supply which provides power to at least one instrument. A pedal comprises a variable resistor that is configured to produce a resistance value within a predetermined range based on an amount of pressure which is being applied to the pedal. The voltage being supplied to the instrument is varied in accordance with the resistance value produced at the pedal.

A multifunctional air pollution reduction device includes a tool and a multifunctional pollutant remover. The multifunctional pollutant remover is adjacent to or integrated with the tool. The multifunctional pollutant remover can not only reduce air pollution, but also help reduce one or more of the following problems when using the tools: noise, vibration and/or slip.

The present disclosure is directed to tools, systems and methods for recontouring/reshaping gum tissue by engaging a consumable tip on a powered tool to abrade/ablate excess or mal-contoured gum tissue to allow better visualization of the tooth/implant structure and reduce the periodontal pockets to provide improved access for cleaning by both the patient and clinician. In some embodiments, the powered tool may use vibrational movement, longitudinal reciprocating movement, rotational movement, reciprocating rotational movement, or a combination of any of the above movement schemes. In some embodiments, a consumable tip may be directed for cleaning tooth/implant surfaces and for recontouring/reshaping gum tissue. The powered tool itself may be constructed to allow the cooling water flow used for operation to be directed to the site where the procedure is carried out for irrigation or to be directed elsewhere at the user's selection to facilitate gum contouring procedures.

A predetermined bone site in a patient selected for restoration is exposed, contacted with an aqueous, methylene blue containing phosphoric acid solution for a time period of at least 3 minutes but no more than about 15 minutes, and thereafter cleansed ultrasonically to remove any bacteria that may be present. Preferred phosphoric acid concentration in the aqueous solution is about 37 percent by weight.

A teeth cleaning apparatus includes a mouthpiece, a transducer, a cleaning liquid supply unit and a power control unit. The mouthpiece includes a containment wall, a hollow ingress tube connector and a vibrator holder. The vibrator holder has a vibrator holder hole and a vibrator holder body, and the transducer has a stationary part and a vibrator part, wherein an end of the stationary part of the transducer is kept in the vibrator holder, and a vibrator part of the transducer is disposed near the containment wall. The cleaning liquid supply unit includes a cleaning liquid container, at least one connecting tube, and a cleaning liquid delivery unit that delivers a cleaning liquid from the cleaning liquid container through the hole of the hollow ingress tube connector of the mouthpiece piece. The power control unit is used for supplying electricity to operate the transducer to generate cavitation bubbles at a vibration frequency to dean teeth.
