A dental tool, comprising:
- a prophy angle;
- and
- an adapter for receiving and driving the prophy angle, wherein
- the prophy angle includes a housing and a rotor, and
- the adapter includes a body, a drive shaft for driving the rotor, a slidable sleeve, and a nose for receiving the prophy angle, wherein
- the rotor includes a lock,
- the housing includes a lock receiver for receiving the lock,
- the lock receiver permitting rotation of the lock within the lock receiver and restraining linear movement of the lock in a direction substantially parallel to a rotational axis of the rotor and towards an opening in the housing, wherein
- the lock having a lock channel configured to receive a tip of a drive shaft,
- the engagement of the lock channel and the tip restraining movement of the rotor in a direction towards the drive shaft and restraining movement of the rotor in the direction substantially parallel to the rotational axis of the rotor, wherein
- in a retracted position of the slidable sleeve, a gear of the drive shaft is revealed, and
- in an extended position of the slidable sleeve, the slidable sleeve at least partially covers the gear.
