Aim The aim of this study was to evaluate the potential of electrochemically activated (ECA) anolyte and catholyte solutions to clean root canals during conventional root canal preparation.
Methodology Twenty extracted single-rooted human mature permanent teeth were allocated randomly into 4 groups of 5 teeth. The pulp chambers were accessed and the canals prepared by hand with conventional stainless steel endodontic instruments using the double-flared technique. One or other of the following irrigants was used during preparation: distilled water, 3% NAOCI, neutral anolyte (300 mg/L of active chlorine), and a combination of neutral anolyte (300 mg/L of active chlorine) and catholyte. The teeth were split longitudinally and the canal walls examined for debris and smear layer by scanning electron microscopy. SEM microphotographs were taken separately in the coronal, middle and apical parts of canal at magnification of x800 to evaluate the debridement of extracellular matrix and at a magnification of x2500 to evaluate the presence of smear layer.
Results Irrigation with distilled water did not remove debris in the apical part of canals and left a continuous and firm smear layer overlying compressed low-mineralised predentine. All chemically active irrigants demonstrated improved cleaning potential compared to distilled water. The quality of loose debris elimination was similar for NAOCI and the anolyte solution. The combination of anolyte and catholyte resulted in improved cleaning, particularly in the apical third of canals. The evaluation of smear layer demonstrated that none of irrigants were effective in its total removal; however, chemically active irrigants affected its surface and thickness. Compared to NAOCI the ECA solutions left a thinner smear layer with a smoother and more even surface. It is also important to note that NAOCI enhanced the opening of tubules predominantly in the coronal and middle thirds of canals, whereas ECA solutions resulted in more numerous open dentine tubules throughout the whole length of canals.
Conclusions Irrigation with electrochemically activated solutions cleaned root canal walls and may be an alternative to NAOCI in conventional root canal treatment. Further investigation of ECA solutions for root canal irrigation is warranted.
