BACKGROUND The major goal of non-surgical periodontal therapy is to reduce or eliminate the subgingival pathogenic microbial flora that is known to be associated with volatile sulfur compounds (VSC). AIM The aim of this study was, therefore, to determine the effect of non-surgical periodontal therapy on the concentration of VSC in mouth air of young adults. SUBJECTS AND METHODS Four hundred...

The instrumental measurement of volatile sulphur compounds is a common practice to assess halitosis. One of the most widespread devices for that purpose is OralChroma(TM), a combination of a semiconductor gas sensor and a compact gas chromatograph (GC) system. Several lines of evidence indicate that although the hardware of OralChroma(TM) is fit for the precise measurement of volatile sulphur c...

introduction : halitosis is a common problem that affects a large portion of the population worldwide. the origin of this condition is oral in 90% of cases and systemic in 10% of cases. the foul odor is caused mainly by volatile sulfur compounds produced by gram-negative bacteria. however, it has recently been found that anaerobic gram-positive bacteria also produce hydrogen sulfide (h 2 s) in ...

OBJECTIVES The aim of this study was to determine whether measurements of volatile sulfur compounds (VSCs) are useful to predict colonization of periodontopathic bacteria. For this purpose, we assessed the relationships among distributions of 4 species of periodontopathic bacteria in tongue coating and dental plaque, oral conditions including VSC concentration in mouth air, and smoking habit of...

Bad breath (halitosis or oral malodor) is a common problem in companion animals as well as humans (Culham and Rawlings 1998). Extensive studies of human halitosis have established that microbial metabolism of proteinaceous substrates in the oral cavity leads to the production of volatile sulfur compounds (VSC) such as hydrogen sulfide and methyl mercaptan. Volatile sulfur compounds and the bact...

Halitosis is an unpleasant condition that causes social restraint. Studies worldwide indicate a high prevalence of moderate halitosis, whereas severe cases are restricted to around 5% of the populations. The etiological chain of halitosis relates to the presence of odoriferous substances in exhaled air, especially the volatile sulphur compounds (VSC) produced by bacteria. The organoleptic diagn...

Objective: Volatile sulfur compounds (VSC), mainly derived from bacteria located in deep crypts at the back of the tongue and from periodontal pockets, are responsible for approximately 90% of halitosis (bad breath, malodor). The objective of this double blind clinical study was to assess the clinical efficacy of a new formulation for halitosis containing a combination of zinc (0.3% Zn) and chl...
