ABSTRACT:
The connection piece (2), which can be fitted in a sealed manner on an opening in the pulp chamber of a tooth, comprises a liquid injector (24) and a discharge duct (25) which lead into the pulp chamber. A vacuum pump (5) is connected to the discharge duct (25) so as to produce bubbles in the liquid inside the tooth. A pressure pump (3) connected to a liquid reservoir conveys the said liquid to the injector (24) so as to produce, by means of impulsion of the said bubbles, a cavitation in the liquid inside the tooth, owing to the action of the pressure.
