A medical or dental treatment device for use in an oral or dental procedure, comprises a base part with a power supply unit and an electrical or electronic control device and a set of different parts for use with the base part. The set of different parts comprises at least one delivery part for a first treatment phase and comprising a sound or ultrasound source, a movable piston and a piston operating element operable to deliver a substance from the delivery part to a treatment site, and at least one active part for use in a second treatment phase to act on the treatment site. The active part comprises a sound source, an ultrasound source and/or an electromagnetic radiation source. The delivery part and the active part are selectively connectible to the base part for use in consecutive treatment phases (the first can precede or follow the second).
