Evaluation of two instrumentation techniques and obturation methods in mandibular first premolar C-shaped canals by Micro-CT
Both PN and WG systems showed similar performance on US after instrumenting C-shaped canals of the mandibular first premolar. WG left significantly more AHTD compared with PN in the apical region. In PN or WG group, SC yielded similar obturation quality when compared with CWC. Both CWC and SC obturation techniques provided inferior filling quality in the apical region than that observed in the coronal region.
