Abstract: An endodontic irrigator tip includes a hub and a cannula coupled to the hub. The hub includes a neck having a distal stop end which ensheathes the proximal portion of the cannula. The distal stop end is angled with respect to the longitudinal axis of the hub. The stop end prevents the insertion of the cannula beyond a desired distance, thereby preventing perforation of the apex of the root canal. The stop end has a substantially greater diameter than the diameter of the cannula Thus, the stop end of the neck rests on the occlusal surface of the crown of the tooth while the cannula extends the desired distance within the root canal.
Abstract translation: 牙根管冲洗头包括一个毂和一个连接在轮毂上的插管。 轮毂包括具有远端止动端的颈部，所述远端止动端包围套管的近端部分。 远端止动端相对于轮毂的纵向轴线成一定角度。 止动端防止套管插入超过所需距离，从而防止根管顶点穿孔。 止动端具有比插管的直径大得多的直径。因此，当套管在根管内延伸所需的距离时，颈部的止挡端位于牙冠的咬合面上。

Abstract: A dental irrigating and aspirating instrument utilizes a cannula with a reduced diameter extended member shaped to occlude the apical foramen while conducting irrigating fluid into the apical terminations of root canal preparations. The extended member also serves to occlude the apical foramen while conducting fluid and debris out of the apical regions during aspiration. The extended member can be shaped with a cutting surface to prepare a base for the root canal preparation and root canal filling. Use and fabrication of the instrument for irrigation and aspiration of the fullest depths of the gingival sulci and periodontal pockets in periodontic practice is also described. A handpiece is described that retains the instrument allowing manipulation of the instrument and control of fluids to and from the instrument.

Abstract: A method for restoring a tooth by endodontically preparing the tooth to accept a dental post. Polyacrylic acid solution is supplied to the prepared area afterwhich it is rinsed out and the area dried. A drying agent has been applied to the prepared area and, likewise, the area is dried out. The dental post is then secured in place through the use of a cement. Preferably, the cement is a filled resin cement with the filler material being approximately 15%-30% of the cement. The drying agent is preferably an ethyl-methyl ketone. The invention also includes a kit containing the materials for implementing the method.

Abstract: The pulp canal of a tooth requiring filling is hollowed out using boring bits fitted to and driven by a vibrating instrument; the bits are organized in sets, with a number of discrete sets making up the full range. The abrasive tine of the bits of each set is tapered; its length and tip diameter remain the same throughout the set, whereas the diameter at the point where it joins with the shank increases progressively from the smallest to the largest size.

Abstract: The invention herein comprises methods and products for attaching a crown replacement on an endodontically treated tooth. The superior surface of the tooth is shaped to receive the base of the crown replacement and an interior space is machined into the root canal to accept placement of a post. The instrumented area is then flushed with a chelating agent followed by an organic solvent. A cementing medium having great compressive strength is placed around a post fitted into the cavity. After the cement has set, a quantity of filler material is placed around the remaining exposed part of the post. This post forms the support for the crown replacement. If desired, a preformed crown replacement may be placed over the cemented structure until a permanent crown can be made.
