- Brief Summary
Bad breath or halitosis is caused by specific gases originating from the mouth or the expired air. In most cases the pathology lies within the mouth and in this case receives the name pathologic halitosis of oral cause or oral malodor. The aim of this study is to evaluate the immediate (masking) and long term (therapeutic) effect of commercially available mouth rinses in the treatment of oral malodor. For this volunteers with oral malodor detected by organoleptic evaluation and confirmed by the increase level of sulphur compounds in their breath (VSC) will be asked to use a designated mouthwash. The breath parameters will be assessed at baseline and 15' after the first rinse (15 ml, during 1 minute) and over night at the end of a period of 3 weeks during which the volunteers rinsed twice a day (15 ml, 1 minute) with the assigned mouthwash. The short and long term effect of a stannous fluoride/amine fluoride/zinc rinse; a chlorhexidine/cetylpyridinium chloride/zinc product and a negative control(fluoride rinse and/or water) will be compared.

Group Intervention Description Fluoride rinse Fluoride rinse A fluoride rinse with alcohol was chosen because its similarity in color and aroma to the active rinses. This anti-cavity rinse does not contain any active components and therefore it is not expected to have any anti-malodour activity. Halita Halita Halita is a CHX-containing benchmark product that has proven to be clinically effective against halitosis (Roldan et al, 2003) Meridol Halitosis Meridol Halitosis This study aims to confirm the effect of meridol®Halitosis(AmF/SnF2 and zinc) already observed in volunteers with morning bad breath (physiological)(Wigger-Alberti et al, 2010; Wilhelm et al, 2010)in patients with oral malodor (pathological). Water Water To distinguish the masking effect caused by the formulations and the one caused by the rinsing itself.Only for short term evaluation (15') to not to compromise compliance of patients.
- Primary Outcome Measures
Name Time Method Change from baseline organoleptic score of breath (OLS) after15' and after 3 weeks A trained and calibrated "judge" sniffs the expired air of the volunteer and assesses whether it is unpleasant by using an intensity rating, normally from 0 to 5, with 0 = no odor present, 1 = barely noticeable odor, 2 = slight but clearly noticeable odor, 3 = moderate odor, 4 = strong offensive odor, and 5 = extremely foul odor (proposed by Rosenberg and McCulloch.
Change from baseline in H2S and CH3SH level in breath after 15' and after 3 weeks A portable gas chromatograph (OralChroma™, Abilit Corporation, Kanagawa, Japan) will be used to measures the concentration of hydrogen sulphur (H2S) and methyl mercaptan (CH3SH) in mouth air. The device has been calibrated and validated for its use by the manufacturer.
- Secondary Outcome Measures
Name Time Method Change from baseline global level of volatile sulphur compounds (VSC) after 15' and after 3 weeks A portable device (Halimeter®, Interscan Corporation, model RH-17E, Chatsworth, USA)able to detect sulphur compounds in air will be used according to the manufacturer instructions
Change from baseline microbial load of saliva after 3 weeks A sample of non-stimulated saliva will be collected into a sterile container and kept at 4°C till processing. To the standard culture of the samples (of aerobic and anaerobic incubation at 37°C) a molecular technique (qPCR)of bacterial detection will be added for periodontal pathogens (P. gingivalis, P intermedia, F. nucleatum and A. actinomycetemcomitans) and bacteria usually involved in oral malodour (S. moorei).
Change from baseline microbial load of tongue coating after 3 weeks Tongue coating will be collected by wiping a sterile swab 3 times over the dorsum of the tongue, in the area of the foramen caecum. Till analysis; the tip of the cotton swab will be kept in a vial containing 2ml of reduced transport fluid (RTF). To the standard culture of the samples (of aerobic and anaerobic incubation at 37°C) a molecular technique (qPCR)of bacterial detection will be added for periodontal pathogens (P. gingivalis, P intermedia, F. nucleatum and A. actinomycetemcomitans) and bacteria usually involved in oral malodour (S. moorei).
