Abstract

Background information: During biomechanical preparation, the action of endodontic tools causes the creation of a smear layer. Smear layer reduction not only improves dentinal tubule sanitation but also the three-dimensional sealing of the root canal system. Goal: Using a scanning electron microscope (SEM), determine how well different final irrigation solutions remove smear layers from root canal walls, and measure the concentration of calcium ions in these solutions following irrigation using atomic absorption spectrophotometry with flame. Materials and Procedures To measure the concentration of calcium ions released with 0.2% chitosan, apple cider vinegar, and 15% ethylenediaminetetraacetic acid (EDTA), 40 human maxillary canines were chosen, prepared, and the final irrigation was carried out. The calcium ions were then composed and analysed using atomic absorption spectrometry. SEM was used to assess the elimination of the smear layer from the middle and apical thirds of the root canal. Results: In terms of removing the smear layer, there was a statistically significant difference between 0.2% chitosan and the other treatments. Apple cider vinegar produced the greatest levels of calcium ions, followed by 0.2% chitosan and 15% EDTA. As compared to apple cider vinegar, which promoted the release of the largest amounts of calcium ions compared to the other solutions evaluated, about 0.2% chitosan demonstrated higher smear layer removal.
