Halitosis, or bad breath is a major problem because it can compromise the people relationship life. Often origin is attributed to stomach or nasal or lung problems. However, we know that up to 90 % of cases, the source is in the oral cavity, and so dominant due to the accumulation of plaque on the dorsum of the tongue "cover tongue". Periodontal disease is also directly related to bad breath, so that the accumulation of plaque, periodontal pockets and/or bleeding are aspects directly related to the problem. From the pathogenic point of view, the dietary and bacteria proteins, and the own oral tissues proteins, are degraded by the action of bacterial proteases to amino acids. Rich in sulfur amino acids are the maximum responsible of bad breath. In fact the three most closely related products are hydrogen sulfide, methyl mercaptan and dimethyl sulphide. In this update, we review all these aspects and causes more directly related to the problem, also reviewing the pseudohalitosis and halitophobia concepts.

Keywords : Pathogenesis; halitosis.
