Disclosed is a dental therapeutic device used for infiltrating and/or rinsing tissue or hollow spaces bordered by tissue, particularly tooth tissue or hollow spaces bordered by tooth tissue, with a therapeutic fluid. The inventive device comprises a storage container ( 2 ) for the therapeutic fluid, a hollow needle ( 42 ) for feeding the therapeutic fluid into the tissue, a pump ( 15, 43, 47 ) feeding the therapeutic fluid from the storage container ( 2 ) to the hollow needle ( 42 ), and a pump ( 15, 43, 47 ) sucking therapeutic fluid from the tissue via the hollow needle ( 42 ). All of said components are comprised in a hand-piece-type unit, whereby a very compact dental therapeutic device is created which is easy to handle for the dentist and requires no external units or only units that are generally part of a dentist's practice. |
