Abstract

Objective: This study was designed to asses influence of instumentation with One RECI(Micro Mega, Besancon, France ) on dentin volume and remaining dentin thickness relative to Wave One Gold(Dentsply Maillefer, Ballaigues, Switzerland) utilizing Cone-beam computed tomography.
Materials and methods: 16 human permanent mandibular first molar with two independent mesial canals were chosen randomly and splited into two equal groups 8 each based on root canal preparation system; Wave One group and One RECI group.All the specimens underwent imaging utilizing cone-beam computed tomography (CBCT) to detect dentin thickness and volume before instrumentation. After instrumentation the mesio-buccal canals were scanned using CBCT for evaluation of dentin volume and remaining dentin thickness after instrumentation.
Results: Regarding remaining dentin thickness, For 2 and 3 mm from the furcation level, the change in remaining thickness measured in Wave One Gold group was significantly higher than in One RECI. Regarding dentin volume, The change in volume post-instrumentation measured in Wave One Gold group was significantly greater than that of One RECI group
Conclusion: Within the study's constraints ; One RECI preserve more dentin than Wave One Gold.
