Abstract
An insert for use in an apparatus for scaling of teeth and lavage of the gingival sulcus is provided. The insert comprises a tip for scaling and delivery of lavage fluids, retaining means for retaining the scaling tip in the insert, and a path means for delivering irrigant for scaling or for lavage through the insert and to the end of the scaling tip. The scaling tip is shaped and dimensioned for scaling and lavage below the gumline in periodontal pockets. When a magnetostrictive insert is used, an outlet means is provided to remove stack cooling water from the insert so that stack cooling water does not enter a patient's mouth.
