Lidocaine 0.5% / Cetylpyridinium chloride 0.1% oromucosal gel sugar free

AimTo evaluate the effectiveness of cetylpyridinium chloride (CPC) and chlorhexidine (CHX) mouthwashes (MW) on plaque and gingivitis scores for patients with gingivitis, in brushing as well as non-brushing situations.MethodsA comprehensive search of MEDLINE-PubMed and Cochrane-CENTRAL was conducted to identify clinical and randomised controlled trials comparing CPC and CHX mouthwashes on plaque and gingivitis scores. The staining index was evaluated as a secondary outcome. In addition, the risk of bias was assessed. The data was summarised using a descriptive approach, and whenever possible, a meta-analysis was conducted. The results for brushing and non-brushing studies were presented separately. Grading was applied using the GRADE approach to rate the certainty of evidence.ResultsThe search resulted in 424 unique papers, from which 14 full-text papers providing 18 comparisons were selected. Different concentrations of CPC-MW (0.1%, 0.075%, 0.05%) and CHX-MW (0.2%, 0.12%) were used. The risk of bias was estimated to be low, moderate or high for each study. A meta-analysis for non-brushing models showed a significant favour for CHX-MW in plaque index scores (0.55 [95% CI: 0.19; 0.91], p = 0.003). For brushing, no significant differences were found between CPC-MW and CHX-MW. The descriptive analysis supports these findings. CHX-MW tends to stain more than CPC-MW.ConclusionThere is moderate certainty for a small statistically significant favourable effect of CHX-MW over CPC-MW for plaque control in non-brushing situations, but no difference between them for plaque and gingivitis prevention in brushing situations.
