Abstract
Objectives: This study aimed to evaluate the cleanliness of the pulp chamber and root canal after irrigant activation using different access cavity designs. Materials and methods: 60 human lower mandibular first molars were divided according to access cavity design into three main groups(n=20): guided conservative access cavity design (GCAC), truss access cavity design (TAC), and conservative access cavity design (CAC); each group was further subdivided into two subgroups(n=10): side-vented irrigating needle(A) and Endovac activation system (B). A Pre-operative Cone beam computed tomography (CBCT) was done for all samples. After chemo-mechanical preparation for all samples, samples were sectioned and scanned by scanning electron microscope (SEM) at 500 X to evaluate the remaining debris covering the pulp chamber and mesiobuccal root canals. Results: TAC showed a significant difference from CAC and GCAC. No difference between CAC and GCAC. Conclusion: TAC is an ultra-conservative access cavity design but compromises root canal system cleanliness.
