The change in original canal size and location after canal preparation and after reinstrumentation using a step-back technique was studied in small and large canals with less than 20-degree curvature. Teeth were mounted in jigs and then sectioned. The jig permitted the sectioned teeth to be repositioned exactly. Slides were made of the canal in the coronal,(More)
This study compared the quality of the obturation of small, curved root canals laterally condensed with a medium-fine (MF) finger spreader and one of two types of accessory cones. Thirty small, curved canals of permanent molars were cleaned and shaped, then randomly separated into two groups. They were obturated with a standardized master cone and either MF(More)
An endodontic sealer is required to provide an apical and coronal seal in root canals. No previously reported methods of sealer placement completely coated canal walls. The purpose of this study was to dehydrate canal walls with alcohol and determine if this permitted better sealer coverage. Forty single-rooted teeth were prepared and divided into 4 groups(More)
This study used a special jig system, photography, and a sonic digitizer to evaluate the change in canal size and location after retreatment in 20 teeth with small or large curved canals (greater than 23 degrees). During initial instrumentation, small canals enlarged twice as much as large canals in the coronal and middle areas. During retreatment, small(More)

This study was designed to relate, in molars, the access outline on the occlusal surface to the canal orifices. The occlusal surfaces of maxillary and mandibular molars were photographed and prints made. The crowns were then sectioned at the level of the pulpal floor to expose the canal orifices. Transparent photographs of the orifices were taken and(More)
