Quantitative Analysis of Root Canal System and Apical Part with Vertucci Type II Configuration Following Preparation with Three Different Preparation Systems: A Micro-computed Tomography Study

Objective: Isthmuses are narrow communications between root canals, and form as the result of the merging of the two root canals widening in a buccolingual direction. This widening causes the high ovality of isthmuses. The shaping and cleaning of all root canal systems are regarded as one of the major difficulties in long-oval shaped root canals. This study aims to make quantitative analysis of Vertucci type II root canal systems following preparation with Self-Adjusting file (SAF), Reciproc or Revo-S.
