ABSTRACT Objectives The present study was conducted to compare the cleaning efficacy (debris and smear layer removal) of hand and two NiTi rotary instrumentation systems (K3 and ProTaper). Materials and methods Sixty single rooted human maxillary anterior teeth decoronated at the cementoenamel junction were used. All the specimens were divided into four groups of 15 teeth each, group I—ProTaper rotary instrumentation done, group II—K3 rotary instrumentation done, group III—Stainless steel K-file instrumentation done, group IV—root canal irrigation without instrumentation. Root canal preparation was done in a crown down manner and 3% sodium hypochlorite was used as irrigant after each file followed by final rinse with 5 ml of 17% EDTA solution, then specimens were scanning electron microscopic (SEM) examination. Results Statistical analysis was done using one-way ANOVA followed by post hoc Tukey's HSD test. Group I showed highly statistical significant difference compared to other groups. There was no statistically significant difference considering smear layer at any levels among the groups with no smear layer formation in group IV. Conclusion ProTaper rotary instrumentation showed the maximum cleaning efficacy followed by K3 rotary instrumentation in the coronal, middle and apical thirds of the root canal. Clinical significance ProTaper rotary instruments are more efficient than hand and K3 rotary instruments during root canal treatment.

Level Of Significance

The aim of our study was to measure the cleaning efficiency of irrigating solutions used during endodontic treatment regarding smear layer removal from the root canal dentin walls. Ethylenediaminotetraacetic acid (EDTA) 17%, citric acid (CA) 10% and sodium hypochlorite (NaOCl) 2,5 % solutions were tested as final irrigating solutions. The study was conducted on extracted teeth, divided in four groups according to the irrigation protocol used. The specimens were analyzed by scanning electron microscopy and the amount of smear layer present at apical, middle and coronal level was recorded, based on a scoring system. Data were statistically analyzed using Kruskal-Wallis and Friedman test and the level of significance was set at p<0.05. In the coronal and middle segments of dental roots we noticed no statistically significant difference between EDTA and CA in smear layer removing capacity. Final irrigation with 17% EDTA proved to be more efficient than 10% CA and 2,5% NaOCl in smear layer removal at apical level of the root canal, with p<0.05 (p=0.042), which is an important area for disinfection in endodontic treatment.
