An initial investigation of the bending and torsional properties of Nitinol root canal files.
The Nitinol files were found to have two to three times more elastic flexibility in bending and torsion, as well as superior resistance to torsional fracture, compared with size #15 stainless steel files manufactured by the same process. Expand
Canal configuration in the mesiobuccal root of the maxillary first molar and its endodontic significance.
The frequency of occurrence of the bifurcated or double canal must be taken into consideration when surgical treatment is planned and as a possible cause of otherwise unexplained failure in patients with mesiobuccal roots. Expand
Diagnosis and possible causes of vertical root fractures.
This study suggests that excessive force during lateral condensation of the gutta-percha caused 84.38 percent of the fractures. Expand
An in vitro comparison study to quantitate the debridement ability of hand, sonic, and ultrasonic instrumentation.
Sonic and ultrasonic instrumentation were significantly faster in preparing the root canal system than hand instrumentation in this study and exhibited the greatest percentage of canal and isthmus cleanliness. Expand
Techniques in clinical endodontics
Phase II trial of oral rubitecan in previously treated pancreatic cancer patients.
The overall risk-benefit profile of oral rubitecan appears promising, supporting further evaluation in phase III trials in patients with refractory and chemotherapy-naive pancreatic cancer. Expand
Alveolar bone loss associated with vertical root fractures. Report of six cases.
Six cases of vertical root fractures accompanied by vertical bone loss are presented, and the definitive treatment in each case was extraction of the tooth or root amputation. Expand
Bacteremia after topical use of prednisolone in infected pulps.
Expanded use of the electronic canal length measuring devices.
A rapid and accurate method for confirming the presence of a root or pulpal floor perforation is described and three cases are presented which demonstrate the accuracy of the presented method. Expand
Use of a hemostatic agent in the repair of procedural errors.
Three clinical cases are presented demonstrating the viability of using hemostatic agents in providing a matrix for the correction of furcal or post perforations and for obturating teeth with large apical foramina. Expand
