Abstract: This study compared the effect of intermediate flush with distilled water delivered by conventional irrigation, EndoVac microcannula or Self-Adjusting File (SAF) system in the prevention of chemical smear layer (CSL) formation. Thirty human premolars were used. Canals were prepared with Reciproc system and 5.25% NaOCl. After chemomechanical preparation, samples were divided in 3 groups (n=10) according to the intermediate irrigation protocol with distilled water using: conventional irrigation, EndoVac microcan… Show more

“…A limitation of the present study was the lack of possibility to state that there was indeed no formation of any type of precipitate, since it may be impregnated inside the dentinal tubules as previously demonstrated by scanning electron microscopy (18,23,29,30). The formation of precipitates inside the dentinal tubules is a concern, as it may compromise dentin permeability, intracanal diffusion of the medication, filling ability and tooth pigmentation (23,28,30).…”

“…This is due to the accumulation of smear layer at the apical of the teeth. 15 Based on the result of this study, it can be concluded that the gutta percha Eucalyptol solvent has a higher average value of apical leakage compared to Citrus Oil and Xylene after root canal re-treatment. There is no significant difference between Orange Oil, Eucalyptol, and Xylene.…”

“…In addition, these could be due to the need of increasing value of apical preparation size which is required for the microcannula to reach the full working length. Increasing the apical size will give a lower possibility of occlusion for the microcannula holes and subsequently more contact with the root canal wall and a better irrigation quality (35,36) . Some studies concluded that the efficiency of EndoVac system in removing the smear layer was better than the conventional irrigation at 1 mm from the working length which is consistent with this study (14,37,38) .…”
