Abstract
OBJECTIVE
The present study aimed to establish the efficacy of sodium hypochlorite mouthwash (NaOCl-MW) compared with a control mouthwash on plaque and clinical parameters of periodontal disease.
METHODS
MEDLINE-PubMed, Embase and Cochrane-CENTRAL databases were searched for clinical trials on patients with gingivitis or periodontitis that assessed the effect of NaOCl-MW in comparison with a negative or positive control on plaque index (PI), gingival index (GI), and bleeding index (BI) scores and probing pocket depth (PPD). Data were extracted from the eligible studies.
RESULTS
Seven eligible papers were retrieved, which together represented six clinical trials. The studies showed considerable heterogeneity regarding methodological and clinical aspects that did not permit a meta-analysis. Two of the three studies in which NaOCl-MW was compared with a negative control showed that NaOCl-MW significantly reduced PI, GI and BI, and no effect was found on PPD. In three studies, NaOCl-MW was assessed using chlorhexidine mouthwash (CHX-MW) as a positive control; no difference was found for GI and BI. One of the three comparisons showed a statistically significant PI score favouring NaOCl-MW. One study measured PPD and found it to be significant in favour of NaOCl-MW.
CONCLUSIONS
Studies with a negative control group provided very weak quality evidence for a very small beneficial effect of NaOCl-MW on PI, GI and BI scores. Studies with a positive control group provided very weak quality evidence that NaOCl-MW had a similar effect as CHX-MW on PI, GI and BI scores. The outcome for PPD was inconclusive.
