In the original article, there was a mistake in Table 2, as published. In the column “Main Outcome,” there were non-clear indications of outcomes. The corrected Table 2 appears below.

Characteristics of the studies.
AT, After Treatment; BT, before treatment; PUI, Passive Ultrasonic Irrigation.
Following the previous point, Figure 2 has been updated. To avoid repeating data “Outcome,” already reported in Table 2, the authors modified Figure 2, which appears corrected below.
Figure 2
Following the previous points, the description in the original article has been updated. Two corrections have been made to section Results, subsection Irrigating Solutions. The corrected paragraphs appear below:
Rocas et al. [38] compared the effectiveness of 2% CHX with that of 2.5% NaOCl using a total volume of 15 mL for both irrigants but did not report the application time. In both groups, the mean number of bacterial cells decreased significantly after irrigation (p < 0.01). The rate of reduction in detectable bacteria was 40 and 44% in the treatment group (2% CHX) and in the control group (2.5% NaOCl), respectively. However, no statistically significant difference was observed upon comparing the mean number of bacterial cells between groups (p > 0.05) [38].
Zandi et al. [39] compared the effectiveness of 2% CHX with that of 1% NaOCl using a total volume of 10 mL for both irrigants but did not report the application time. In both groups, the mean number of bacterial cells decreased significantly after irrigation (p < 0.01), and the rate of reduction was higher than 99% (99.6% in the treatment group and 99.8% in the control group). However, no statistically significant difference was observed upon comparing the detectable bacteria between groups (p > 0.05).
The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated.
