In a device for cleaning cavities, especially tooth cavities and tooth root channels, an alternating pressure generator is directly connected to the cavity to be cleaned via a connecting line. To the alternating pressure generator are connected a supply line and a discharge line having narrowed sections as flow resistors, through which a rinsing solution flows. As the rinsing solution flows through, the alternating pressure generator can give rise to cavitation in the cavity with the generation and implosion of gas bubbles so that microstructures in the cavity can also be cleaned. This device is distinguished by simple mechanical construction and small size.

Dans un dispositif qui permet de nettoyer des cavités, notamment des cavités dentaires (1) et des canaux radiculaires (2), un générateur de pression alternée (9) est relié directement à la cavité (1, 2) à nettoyer, par l'intermédiaire d'une conduite de raccordement (7). Une conduite d'amenée (14) et une conduite d'évacuation (19) sont raccordées au générateur de pression alternée (9). Ces conduites présentent des sections rétrécies (17, 18) faisant office de résistances hydrauliques et sont parcourues par une solution de rinçage (16). Lorsque la solution de rinçage (16) circule à travers lesdites conduites, le générateur de pression alternée (9) provoque un effet de cavitation dans la cavité (1, 2) à traiter, accompagné de la production et de l'implosion de bulles de gaz, de sorte que les microstructures de la cavité (1, 2) peuvent également être nettoyées. Ce dispositif se caractérise en ce qu'il est de structure mécanique simple et de dimension réduite.
