A comparison of weights of debris extruded apically by conventional filing and Canal Master techniques.
Sixty extracted human teeth were divided into three groups of 20 each. Apically extruded debris and irrigant were collected, dried, and weighed by the following three instrumentation techniques: (a)Expand

Abstract Commercially available gutta-percha cones can be effectively decontaminated by immersion for 6 minutes or more in polyvinylpyrrolidone-iodine prior to insertion into root canals.
Scheuermann's Kyphosis— Long-Term Results of Milwaukee Brace Treatment
A review of 203 patients with Scheuermann's kyphosis is presented. The modified Milwaukee brace was used in 62 patients. Thirty-nine patients wore the brace for an average of 18 months. TheExpand
Effectiveness of ultrasonics and calcium hydroxide for the debridement of human mandibular molars.
This study evaluated the ability of ultrasonics and calcium hydroxide to remove pulp tissue debris from the mesial root canals of human mandibular molars. All teeth were instrumented using a standardExpand
The effect of four preparation techniques on the amount of apically extruded debris.
The amounts of root canal material extruded from extracted teeth using four instrumentation techniques were compared. Eighty extracted human mandibular premolars with single canals and rootExpand

A tooth with cervical resorption possibly caused by an internal bleaching technique was treated with calcium hydroxide. This case had characteristics in common with the other seven cases that haveExpand
Another look at root canal instrumentation.
Several aspects of root canal instrumentation need additional research. Various factors must be considered in an analysis of instrumentation of the root canal system: the dentin that is cut; theExpand

A flaring technique for opening the cervical portion of mesial root canals in mandibular molars prior to canal instrumentation was compared with a conventional filing technique. The experimentalExpand
Effectiveness of a brush in removing postinstrumentation canal debris.
The purpose of this study was to evaluate the effectiveness of a brush in removing debris in the root canal after endodontic instrumentation. Seventeen extracted human maxillary first molars withExpand
The effects of four instrumentation techniques on root canal shape.
Recently, a new methodology was introduced for the study of root canal instrumentation. It has the advantages of using extracted human teeth in which original canal shapes can be compared withExpand
