“…9 Our results with Breathtron TM are comparable to the previous studies. These results and recent study 13 of Breathtron TM suggest that this sulfide monitor is recommendable to measure VSC of mouth air. However, value of this monitor does not stand for absolute oral malodor which originates from not only VSC but other volatile compounds.…”

“…We used mean score as representative organoleptic score of each mouth air. 11,13,14 To standardize oral condition as possible, all subjects were instructed to produce a sound ''ra, ra, ra, ra, ra,'' three times clearly and breathe out just before every measurement. According to the result of organoleptic score and sulfide level by GC, we defined standard range of output value of the sulfide monitor for clinical use as follows: 0-250 ppb: normal (responding to no malodor), over 250 to 600 ppb: slight (responding to slight malodor), over 600-1500 ppb: clearly noticeable (responding to clearly noticeable malodor), over 1500-3000 ppb: strong (responding to strong malodor).…”

“…After subjects closed their mouth for 3 minutes, the Teflon ® tube connected to the auto-injector was gently inserted into the center of the oral cavity through the lips and teeth, while the lips remained closed. Following aspiration of 20 mL of mouth air with a syringe connected to the outlet of the auto-injector, a 10 mL sample of air was transferred to the column and chromatograph [31]. A sulfur chemiluminescence detector that specifically responds to sulfur was used.…”

BackgroundPrevious research has shown the oxidizing properties and microbiological efficacies of chlorine dioxide (ClO2). Its clinical efficacies on oral malodor have been evaluated and reported only in short duration trials, moreover, no clinical studies have investigated its microbiological efficacies on periodontal and malodorous bacteria. Thus, the aim of this study was to assess the inhibitory effects of a mouthwash containing ClO2 used for 7 days on morning oral malodor and on salivary periodontal and malodorous bacteria.Methods/DesignA randomized, double blind, crossover, placebo-controlled trial was conducted among 15 healthy male volunteers, who were divided into 2 groups. Subjects were instructed to rinse with the experimental mouthwash containing ClO2 or the placebo mouthwash, without ClO2, twice per day for 7 days. After a one week washout period, each group then used the opposite mouthwash for 7 days. At baseline and after 7 days, oral malodor was evaluated with Organoleptic measurement (OM), and analyzed the concentrations of hydrogen sulfide (H2S), methyl mercaptan (CH3SH) and dimethyl sulfide ((CH3)2S), the main VSCs of human oral malodor, were assessed by gas chromatography (GC). Clinical outcome variables included plaque and gingival indices, and tongue coating index. The samples of saliva were microbiologically investigated. Quantitative and qualitative analyses were performed using the polymerase chain reaction-Invader method.Results and DiscussionThe baseline oral condition in healthy subjects in the 2 groups did not differ significantly. After rinsing with the mouthwash containing ClO2 for 7 days, morning bad breath decreased as measured by the OM and reduced the concentrations of H2S, CH3SH and (CH3)2S measured by GC, were found. Moreover ClO2 mouthwash used over a 7-day period appeared effective in reducing plaque, tongue coating accumulation and the counts of Fusobacterium nucleatum in saliva. Future research is needed to examine long-term effects, as well as effects on periodontal diseases and plaque accumulation in a well-defined sample of halitosis patients and broader population samples.Trial registrationClinicalTrials.gov NCT00748943

“…This gives the ability to distinguish between different compounds that cause halitosis. It is therefore one of the most accurate tests currently available, both in terms of its objectivity and sensitivity in detecting low concentrations of molecules . However, this technique is not easily implemented clinically using traditional chromatographs because of the relatively high cost of the equipment, the requirement for highly trained operators, and the extensive procedures involved.…”

Halitosis, an offensive breath odour, has multiple sources and negative impacts on people’s social interactions and quality of life. It is important for health care professionals, including general physicians and dental professionals, to understand its aetiology and risk factors in order to diagnose and treat patients appropriately. In this study, we have reviewed the current literature on halitosis regarding its prevalence, classification, risk factors, sources, measurement and treatment.
