- Objectives This study aims to assess the effects of rinsing with zinc- and chlorhexidine-containing mouth rinse with or without adjunct tongue scraping on volatile sulfur compounds (VSCs) in breath air, and the microbiota at the dorsum of the tongue. Material and methods A randomized single-masked controlled clinical trial with a cross-over study design over 14 days including 21 subjects was performed. Bacterial samples from the dorsum of the tongue were assayed by checkerboard DNA–DNA hybridization. Results No halitosis (identified by VSC assessments) at day 14 was identified in 12/21 subjects with active rinse alone, in 10/21with adjunct use of tongue scraper, in 1/21 for negative control rinse alone, and in 3/21 in the control and tongue scraping sequence. At day 14, significantly lower counts were identified only in the active rinse sequence ( p < 0.001) for 15/78 species including , Fusobacterium sp., Porphyromonas gingivalis , Pseudomonas aeruginosa , Staphylococcus aureus , and Tannerella forsythia . A decrease in bacteria from baseline to day 14 was found in successfully treated subjects for 9/74 species including: P. gingivalis , Prevotella melaninogenica , S. aureus , and Treponema denticola . Baseline VSC scores were correlated with several bacterial species. The use of a tongue scraper combined with active rinse did not change the levels of VSC compared to rinsing alone. Conclusions VSC scores were not associated with bacterial counts in samples taken from the dorsum of the tongue. The active rinse alone containing zinc and chlorhexidine had effects on intra-oral halitosis and reduced bacterial counts of species associated with malodor. Tongue scraping provided no beneficial effects on the microbiota studied. Clinical relevance Periodontally healthy subjects with intra-oral halitosis benefit from daily rinsing with zinc- and chlorhexidine-containing mouth rinse.

- Background: Around 30% of the adult population has problems with Halitosis. Halitosis is caused by volatile sulfur compounds (VSC) by bacteria. The aim of this study was to evaluate the short term effect on halitosis using a zinc-lacete-chlorhexidine containing mouth rinse (SB12). Materials and methods: Twenty-five adults with halitosis were included in a clinical randomized double blind cross over study. Four test periods, each 2 weeks long separated by washout periods of 1 week was used to evaluate 4 treatments: A) SB12, B) placebo C) SB12 + tongue scraper, and D) placebo + tongue scraper. Registration of VSC using a Halimeter was done at Day 1 before rinsing, immediately after rinsing, after 30 minutes and at Day 14. Results: A reduction on VSC 30 min following treatment compared to baseline was found for substance A, C, D (P < 0.000). A reduction at Day 14 was only found for substance A (P < 0.004). Comparing treatments, significant differences was found at all time points between A and B (P < 0.01, P < 0.003, P < 0.042 respectively) and between C and B immediately after rinsing and 30 min after rinsing (P < 0.008, P < 0.003). There was non significant difference between treatment A and C or between treatments B and D. Conclusion: Rinsing with a zinc-lacete - chlorhexidine containing mouth rinse (SB12) demonstrated short term reductions of VSC. Tongue scraper alone had a limited effect on oral halitosis. The addition of tongue cleaning using a tongue scraper did not improve the results obtained by rinsing alone.
