Objective: The aim of the study were to observe the anti-microbial activity of Streptococcus salivarius K12 against Prevotella intermedia, and influencing effect to decrease volatile sulfur compounds (VSCs).
Methods: After P. intermedia was cultured with or without S. salivarius K12, VSCs were measured by Oral Chroma. In order to analyze the mechanism for malodor control effect, anti-microbial activity of S. salivarius K12 againist P. intermedia was assessed. After the spent culture mediu or whole bacteria of S. salivarius K12 was mixed with P. intermedia, a mount of VSCs was also checked by use of Oral Chroma.
Results: When S. salivarius K12 was co-cultured P. intermedia, hydrogen sulfide level was decreasing tendency by high concentration of S. salivarius K12, and lower than those of single-cultured (p＜0.05). Antimicrobial effect was revealed on 70% concentration of S. salivarius K12 for P. intermedia.
Conclusion: S. salivarius K12 were considered for decreasing VSCs level originated from P. intermedia.
