The effect of Brazilian propolis type-3 against oral microbiota and volatile sulfur compounds in subjects with morning breath malodor.

Objectives: To evaluate propolis type-3 mouthrinse effects on the concentration of volatile sulfur compounds (VSCs) and on tongue dorsum microbial profile.

Materials And Methods: A three-step double-blind, crossover, randomized study with 10 individuals divided into three groups: I-placebo (P); II-ethanolic extract of propolis type-3 3% (EEP); and III-chlorhexidine 0.12% (CHX) and instructed to rinse twice daily for 5 days.

Effect of toothbrushing discontinuation on morning volatile sulfur compounds in periodontally healthy subjects.

Purpose: To follow up the variations of early morning concentrations of oral volatile sulfur compounds (VSCs) in periodontally healthy subjects who refrained from toothbrushing during a period of 5 days while continuing with other hygiene procedures.

Materials And Methods: Thirteen subjects volunteered for this study. At baseline, all subjects stopped brushing their teeth for 5 days, but continued using dental floss and a tongue scraper twice daily.
