Abstract
An apparatus for scaling of teeth and lavage of the gingival sulcus is provided. The apparatus comprises a base unit which contains reservoirs for the medicaments used in the lavage procedure, and a handpiece connected to the base unit by a conduit, which contains an insert for scaling of teeth. Switches on the base unit and a footswitch make it possible for the practitioner to use the apparatus for scaling only, lavage only, or for simultaneous lavage and scaling.
Claims22
An apparatus for scaling of teeth and for therapeutic lavage comprising:
- (a) a base unit having at least two fluid reservoirs each of said reservoirs having an outlet;
- (b) a handpiece having a handle and an insert, said insert having tooth scaling means, said insert being connected to said outlet by a first conduit means, said first conduit means communicating with said outlets of said fluid reservoirs to supply fluid from said fluid reservoirs to the subgingival area of treatment;
- (c) a first switching means for controlling dispensing of medicament containing fluid from said reservoirs through said first conduit means to said handpiece;
- and
- (d) a second switching means for controlling cooling fluid passage through a second conduit means connected to said handpiece to provide cooling fluid through said insert, whereby medicament containing fluid may be dispersed through said insert without scaling or simultaneously with scaling.
An apparatus for therapeutic lavage and scaling of teeth comprising:
- a reservoir,
- a base unit,
- a handpiece,
- a first switching means for controlling dispensing of medicament containing fluid,
- a medicament conduit, and
- a second switching means for controlling water passage from a water supply,
- said reservoir being supported by said base unit, said handpiece having a handle and an insert, said insert having tooth scaling means, said first switching means being connected to said reservoir, said reservoir being connected to said medicament conduit, said medicament conduit being connected to said insert, said handpiece being connected to said second switching means, whereby medicament containing fluid is readily applied from said reservoir to a subgingival area of treatment through said insert, and water is readily passed to said handpiece.
A method for therapeutic lavage and scaling of teeth comprising:
- providing a reservoir, a base unit, medicament conduit, a handpiece, a first switching means for controlling dispensing of medicament containing fluid, a second switching means for controlling water passage from a water source, said handpiece having a handle and an insert, said insert having tooth scaling means, said reservoir being supported by said base unit, said first switching means being connected to said reservoir, said reservoir being connected to said medicament conduit;
- said medicament conduit being connected to said insert, said handpiece being connected to said second switching means,
- applying medicament containing fluid from said reservoir through said insert to a subgingival area of treatment, and
- conveying cooling water from said water source through said insert.
