Effectiveness of Oxidative Potential Water as an Irrigant in Pulpectomized Primary Teeth

Abstract

Objective: The aim of this study was to evaluate the effectiveness of oxidative potential water (OPW) as an irrigating solution in reducing bacterial loading in necrotic pulpectomized primary teeth. Study design: Forty necrotic teeth were included, 20 irrigated with OPW (experimental group) and 20 with 1% NaOCl (control group); in both groups, 2 microbiological samples from within the canals were taken with a sterile paper point, the first before irrigation (immediately before opening the crown), and the second after instrumentation and final irrigation (before filling). All samples were evaluated by McFarland's scale. Results: After the samples were analyzed before and after irrigation in the control group, there was a significant decrease in bacterial load, as in the experimental group (P < 0.0001). When both groups were compared post irrigation, no significant difference was observed (P = 0.1519). Conclusion: The OPW was as effective as the NaOCl and is suggested as an alternative for irrigating after pulpectomy of necrotic primary teeth.

The effect of a chemomechanical protocol to eliminate microorganisms from pulpectomized primary teeth: three case reports.

“…4,6,7 Studies that have examined the bacterial community of infected root canals of primary teeth before and after chemomechanical preparation (CP) are scarce in the literature. [8][9][10] These studies show a reduction in microorganisms, however, unlike the present study, they did not associate the performance of pulpectomy with the presence of microorganisms before and after CP, especially after long-term monitoring. Therefore, the analysis of this long-term correlation becomes relevant.…”

Intracanal irrigants for pulpectomy in primary teeth: a systematic review and meta‐analysis

“…The efficacy of NaOCl as a control irrigant was compared with OPW, and with MTA, in terms of CFU/mL. Based on the homogeneity between the studies, it was decided to combine the results, despite their being different experimental groups.…”

“…A meta-analysis was conducted with only two studies: those of Valdez-Gonz alez et al 34 and of Farhin et al 37 , which exhibited sufficient crude data, and all of the possible outcomes were included. These combined studies (Figs 2 and 3) did not show significant heterogeneity (Q = 1.42; degrees of freedom = 1; P = 0.2326) according to the restricted maximal likelihood model.…”
