A Comparative SEM Evaluation of Cleaning Efficacy of Endo Finisher, Self Adjusting File and Conventional Irrigation Regimen in Simulated Internal Resorptive Defects: An in vitro Study
Journal Title: Journal of Clinical and Diagnostic Research - Year 2018, Vol 12, Issue 1
Abstract
Introduction: Difficulties associated with the comprehensive cleaning and disinfection of the canals with Internal Resorptive Defects (IRD) still remains a challenge. Hence, it is essential to improvise the existing or develop new root canal cleaning techniques. Aim: To comparatively assess the cleaning efficacy of XP Endo finisher (XP), Self-Adjusting File (SAF) and Conventional Syringe Needle Irrigation (CSNI) from mechanically unreachable region like Internal Root Resorption (IRR) in the middle third of relatively straight root canals. Materials and Methods: The root canals of 30 freshly extracted single rooted human maxillary anterior teeth were prepared using Nickel (Ni) Titanium (Ti) rotary files up till apical size 40. The prepared teeth were longitudinally split into two halves and internal resorptive defects were simulated in each half at uniform level by a demineralisation protocol with nitric acid and Sodium Hypochlorite (NaOCl) solutions in a sequential manner. Thereafter, the prepared specimen halves were reattached and randomly allocated to three equally sized groups (n=10) according to the technique to be used for smear layer/debris removal as follows: Group 1-CSNI, Group 2-SAF, Group 3-XP Endo finisher. The finally prepared specimens were again detached and evaluated for cleaning efficacy using Scanning Electron Microscope (SEM). One-way ANOVA test for means of the group and Post–Hoc Tukey’s test for interrelationship between groups were used for statistical analysis. Results: The mean scores of SAF and XP Endo Finisher group depicted comparatively cleaner canal surfaces and did not differ statistically (p>0.001). However, both the groups showed statistically significant difference with CSNI group (p<0.001). Conclusion: Maximum cleaning efficacy was obtained with SAF and EF followed by CSNI. In the cases of IRD the debris from resorptive defects may be adequately cleaned by both SAF and XP.
