Brief summary: In a previous study the prevention of halitosis by the herbal formula and delivery system (SmellX), were established both in vitro and clinicaly. The duration of relief was established as long as 8 hours. In this study the investigators intend examine the day long efficacy of SmellX.

Detailed description: Oral malodor is a common complaint among dental patients. This condition derives in most cases form the putrefactive activities of oral microorganisms, primarily anaerobic Gram negative bacteria. These bacteria reside on various locations within the oral cavity (e.g. tongue dorsum, interdental space, periodontal pockets, faulty and leaky restorations and tonsils) and breakdown salivary and oral proteins into their amino acid building blocks. Some of these amino acids (e.g. methionine and cysteine) are further metabolized yielding malodorous volatile sulfide compounds (VSC) such as methylmercaptan and hydrogen sulfide.The tongue dorsum and especially its posterior portion are considered the key location for this process. Therefore, the treatment regiment includes in most cases a daily use of tongue scrapers and mouthwashes. Indeed, a recent Cochrane systematic review found tongue scrapers to have short-term efficacy in controlling halitosis.

However, the use of tongue scrapers is unpleasant and induces in many cases a strong gag reflex, and apparently has very little effect on bacterial load of the tongue.

Furthermore, some mouthwashes have been shown to cause adverse side effects such as tooth staining. In a previous study we performed a set of related experiments on a new sustained release delivery system in the form of an adhesive tablet containing an herbal formulation. The adhesive tablet is applied to the palate. This places it right above, and in direct contact with the tongue dorsum, thus allowing a sustained release of the active ingredients directly to the target site. The ingredients of the herbal formulation have been previously shown to reduce malodor production in a salivary incubation assay. We tested the effect of this system on oral malodor production and VSC levels in a young healthy population, and the antimicrobial effect of its active ingredients on three known oral pathogens (Streptoccocus mutans, Porphyromonas gingivalis and Candida albicans. In this study we intend to examine a day long protocol to achieve a relief from oral halitosis for 24 houres.
