Endodontic working width: current concepts and techniques.

Root canal morphology is a critically important part of conventional and surgical endodontics (root canal therapy). Many in vitro studies have recorded the scales and average sizes of root canals, but there have been few clinical attempts to determine the working width. In the absence of a study that defines what the original width and optimally prepared horizontal dimensions of canals are, clinicians are making treatment decision without any support of scientific evidence. This article provides definitions and perspectives on the current concepts and techniques to handle working width-the horizontal dimension of the root canal system-and its clinical implications.

Effect of modified Hedstrom files on instrumentation area produced by ProFile instruments in oval canals.

OBJECTIVE: To study the effect of a modified Hedstrom file called IqFile on the instrumentation shape of oval canals prepared with ProFile instruments. STUDY DESIGN: Fifty extracted premolars were divided into 3 groups of 16 teeth each. Group 1 was subjected to ProFile 0.04 rotary instrumentation to a size 6. Group 2 followed the same technique, but also received buccolingual hand instrumentation with IqFiles to ISO size 70. Group 3 was instrumented similarly to group 2 but unmodified Hedstrom files were used. Teeth were sectioned at 1 and 3 mm from working length and photographed at 26x magnification. AutoCAD was used for measuring the percentage of instrumented area of the canal. RESULTS: ANOVA revealed that Group 2 was significantly better than Groups 1 (P=.00) and 3 (P=.00) at the 1 mm level. At the 3 mm level Group 2 was significantly better than Group 1 (P=.03), but no differences were found between Groups 2 and 3 (P=.15). CONCLUSION: The combination of ProFile and IqFile was found more effective in instrumenting oval canals at both the 1 and the 3 mm levels. However, at the 3 mm level no difference was detected between the use of IqFiles and the use of unmodified Hedstrom files.
