A comparison of pulpectomy alone versus pulpectomy with trephination for the relief of pain.

Patients who when initially seen have pain of endodontic origin have a higher incidence of posttreatment pain than those who are pain-free pretreatment. The purpose of this study was to compare two methods of treatment--pulpectomy alone or pulpectomy with trephination--for the reduction of posttreatment pain in patients presenting with acute periradicular pain of pulpal origin. Seventeen patients with pretreatment pain were studied.

An in vitro evaluation of microleakage of a new root canal sealer.

An in vitro dye leakage study was performed to compare the apical microleakage of Ketac-Endo root canal sealer with that of Roth's 801E and AH26 sealers. Sixty-four single-rooted human teeth were instrumented and randomly divided into four groups. Three groups were obturated with laterally condensed gutta-percha and either Roth's 801E, AH26, or Ketac-Endo as the sealer.

Histological response to titanium endodontic endosseous implants in dogs.

Endodontic endosseous implants stabilize teeth that have crown-root ratios compromised by periodontal disease, trauma, or apical resorption. By increasing the crown-root ratio, the implant improves the prognosis of the tooth, thus increasing its longevity. The purpose of this study was to evaluate, in vivo, the healing response to a newly introduced titanium endodontic implant.

Leakage of amalgam and Super-EBA root-end fillings using two preparation techniques and surgical microscopy.

An in vitro dye leakage study was conducted to test the root-end sealing ability of amalgam with varnish or Super-EBA using two root-end preparation techniques and surgical microscopy. Sixty-four single-rooted teeth were instrumented and obturated with gutta-percha. Teeth were randomly placed into four groups.

The lateral radiograph: an aid to labiolingual position during treatment of calcified anterior teeth.

A technique is described to obtain a lateral view of an anterior tooth using a regular periapical film. This procedure helps determine the relative labiolingual position of instruments during the nonsurgical treatment of calcified canals. No additional armamentarium is required other than what is used in the daily practice of endodontics.
