Abstract
A method of lighting a scaling tip including providing a light source electrically connected to a secondary coil, and providing a scaling tip having an arm extending into a primary coil and adapted to be ultrasonically vibrated by the primary coil.
Claims22
A dental method, comprising:
- providing a scaling tip having an arm extending into a primary coil enclosed by a housing and
- sliding a secondary coil over the housing.
An ultrasonic scaler handpiece system, comprising:
- a scaler handpiece housing supporting a scaling tip, enclosing a primary coil, and
- a light source housing supporting a secondary coil and a light source,
- said scaler handpiece housing supporting said light source housing.
A method comprising:
- sliding a lighting sleeve onto a dental handpiece,
- said dental handpiece enclosing a primary coil,
- said lighting sleeve, having a secondary coil, and
- a light source,
- said secondary coil being connected to said light source.
