Overview

Randomized trial demonstrates divergent microbiome and anti-inflammatory impacts of probiotics and antimicrobial rinses in adults with halitosis, indicating distinct therapeutic mechanisms.

Key Points

To evaluate ecological and salivary inflammatory responses to adjunctive probiotic lozenges or antimicrobial mouth rinse in adults with intra-oral halitosis.
A 4-week, three-arm randomized pragmatic trial (N=117 adults; 39 per arm; ClinicalTrials.gov NCT05876321) comparing standard care, Streptococcus salivarius K12 lozenges, and a zinc lactate/CPC/chlorhexidine rinse.
Primary mechanistic endpoints were a qPCR-derived tongue-coating dysbiosis index and salivary inflammatory markers (IL-6, IL-8, TNF-α, MMP-8), evaluated via baseline-adjusted ANCOVA and mediation analysis.
The probiotic arm achieved the greatest reduction in the tongue dysbiosis index (−0.7 ± 0.5 vs. −0.5 ± 0.3 with rinse and −0.2 ± 0.4 with standard care; p < 0.001), with dysbiosis reduction nearly completely mediating malodor improvement (VSC correlation ρ = 0.82).
The zinc lactate/CPC/chlorhexidine rinse drove the largest decreases in salivary IL-8, TNF-α, and MMP-8 (all p < 0.001), though it elicited higher local adverse event rates (53.8% vs. 15.4% for probiotic and 10.3% for standard care).
