Abstract:
AIM:To evaluate the intratubular antimicrobial activity of several oxidant and chelating agents associated with or without surfactants in experimentally infected root canals, using confocal laser scanning microscopy. METHODOLOGY:Twenty-four dentine blocks from bovine incisors were contaminated for 5 days with Enterococcus faecalis (ATCC- 29212). Ten contaminated dentine specimens were irrigated for 5 min with 5.25% NaOCl followed by 17% EDTA for 2 min, and the other 10 with Hypoclean for 5 min followed by Tetraclean NA for 2 min. The remaining four specimens were used as positive and negative controls (two samples each). Then, dentine blocks were stained with Live/Dead BacLight for analysis of the remaining live or dead bacteria using confocal laser scanning microscopy. Comparison between and within groups was performed using the Mann-Whitney test for independent samples and the Wilcoxon signed-rank test, respectively. RESULTS:After exposure to irrigants, the positive control group had a median of 67.41% of viable bacteria (95% CI: 48.15, 78.9), whilst the NaOCl+EDTA group and Hypoclean+Tetraclean NA group had 3.77% (1.28, 15.92) and 0.87% (-0.42, 4.30) of viable bacteria, respectively. These results were significantly different from each other, both overall and distinct by region (cervical and medium third), or depth (superficial and deep layer) (P < 0.01 in all cases). CONCLUSIONS:The use of adjunctive agents reducing the surface tension associated with oxidant and chelating agents improved the antimicrobial activity of irrigating solutions and intratubular decontamination against Enterococcus faecalis, possibly due to better removal of the smear layer and deeper penetration into dentinal tubules.
