Abstract: AIM. The aim of this study was to evaluate bacterial reduction in root canals with the XP-Endo Shaper (XP) and Trunatomy (TN) systems. MATERIALS AND METHODS. Twenty-eight permanent human type I, oval-shaped Vertucci premolars and straight root canals were contaminated with Enterococcus faecalis for 30 days at 37°C. Samples were collected prior to instrumentation. The teeth were divided into two groups (n = 14) and processed with the tested groups at 37°C: XP group – (30/0.04) and TN group – Small (20/0.04) and Prime (26/0.04). Biological samples before and after instrumentation were collected using a sterile paper cone inserted into the canal for one minute. Bacteria were counted using colony forming units (CFU/mL) and results were subjected to Kruskal-Wallis test at 5 level of significance. RESULTS. Both the XP and TN systems significantly reduced bacterial counts (p < 0.0001), but did not eliminate bacteria in the root canals. CONCLUSIONS. Both the Trunatomy and XP-Endo Shaper systems were similar in terms of antimicrobial efficacy, but neither system was able to eliminate bacteria from the root canals.
