ABSTRACT Objective: The purpose of this study was to compare the amount of residual smear layer after root canal instrumentation by using Ni-Ti, M-Wire, and CM-Wire instruments. Materials and Methods: Seventy-two mandibular incisors were randomly divided into six groups according to the system used: WaveOne (WO), Reciproc (RP), Unicone (UC), ProTaper Next (PN), Mtwo (MT), and HyFlex (HF). Afterward, the specimens were cleaved in the mesiodistal and buccolingual direction for analysis by scanning electron microscopy. Results: Considering both directions and root canal thirds, there was no difference between HF, MT, and PN. RP, UC, and WO presented a significant difference between the directions, and the cervical third showed a significantly smaller quantity of residual smear layer compared with the apical third. When the systems were compared among them, there was a significant difference only between RP and WO. Conclusions: Residual smear layer observed after instrumentation with the different systems was similar, except for quantities between the reciprocating systems.

Whatever the technique used for root canal instrumentation; a layer of debris termed “smear layer” is formed. This is a layer composed of an organic and inorganic substance and it harbors bacteria and their by-products. Removing the smear layer enhances the cleaning and disinfecting of root canal walls and grant maximum adaptation of root canal filling materials. Nonetheless, the existence of smear layer can seal the dentinal tubules and decrease the probability of dentinal tubule’s invasion by bacteria and their toxins, this issue is still controversial. Smear layer removal approaches including chemical, ultrasonics, and laser have been widely studied. However, none of them is entirely efficient along the length of all canals or is universally recognized. If the decision was to remove smear layer, irrigating root canals with EDTA followed by NaOCl will fulfill the objective. It is still debatable whether the removal of smear layer will decrease the apical leakage or not. Additional research is required to determine the consequence of removing or preserving the smear layer.
