A Histologic Comparison of the Canal Wall Planning Ability of Two New Endodontic Files,
Abstract
Thirty curved, mesial roots of extracted human mandibular first molars were selected to histologically evaluate the planing ability of two new endodontic files. Mesiolingual canals were serially prepared with one of three types of endodontic files. Conventional K-type files were used as control instruments; and recently marketed K-Flex and Dynatrak files were used as experimental instruments. The difference in canal wall planing ability among the three file types was measured by the percentage of predentin and/or dentin removed from the walls of the mesiolingual canals as compared to the walls of the uninstrumented mesiofacial canals. Statistical comparison of the mean percentage scores of canal wall planed at P<or=.05 showed no statistically significant difference among the three file types. Statistical comparison of the mean operating times at P<or=.05 showed that the Dynatrak file gave instrumentation times that were significantly less than either the K-Flex or the K-type files.
