Evaluation of the flaring in mandibular molars danger zone using ProTaper rotatory system
Journal Title: RSBO - Year 2005, Vol 2, Issue 2
Abstract
The aim of this study was to evaluate in vitro the flaring in mandibular molars danger zone, after root canal instrumentation with the ProTaper rotatory instrument system. Sixty extracted mandibular molars with fully formed apices had the mesial roots sectioned. The specimens were divided into four groups and instrumented until Shaping X, Shaping 1 and Shaping 2 files,respectively. One group was kept as control with no instrumentation. The results submitted to statistical analysis, showed a 1% significant difference among experimental groups, with an enlargement of the flaring in danger zone being directly proportional to the diameter of ProTaper instruments. It is concluded that the use of this instruments on the preparation of mandibular molars is safe because there isn’t any report of root perforation.
