Background: Irrigation plays an important role in the success of pulpectomy procedures. While sodium hypochlorite (NaOCl) has shown effectiveness as an irrigation agent for primary teeth, it is important to note that at higher concentrations, it may induce toxic damage to the periapical region. Consequently, 1% NaOCl may exhibit a lower level of toxicity. However, there are some concerns regarding its antibacterial efficacy at lower concentrations. Therefore, the main objective of this study was to evaluate the effectiveness of 1% and 3% sodium hypochlorite irrigation in reducing the bacterial load within the primary teeth root canals. Methodology: A total of 40 participants were allocated into two groups of 20 each. Group 1 (n = 20) canal was irrigated using 1% sodium hypochlorite, and Group 2 (n = 20) canal was irrigated using 3% sodium hypochlorite. Microbial sample was collected from the root canal before and after irrigation with respective solutions. The sample was transferred to the ultra-snap tube, which was then placed in the luminometer. Results: The mean colony count of the 3% sodium hypochlorite was 3631.9 ± 318.32, and that of the 1% sodium hypochlorite was 3596.15 ± 216.65. A paired t-test revealed that in the 1% and 3% sodium hypochlorite groups, the colony counts significantly reduced postirrigation. Conclusion: In conclusion, the study demonstrates that 1% NaOCl is as effective as 3% NaOCl in lowering bacterial count. As a result, the use of 1% NaOCl as an irrigant can be considered in clinical practice. [ABSTRACT FROM AUTHOR] |
