Title: Halitosis: Screws with a smell


Biography: Curd M.L. Bollen


Halitosis is still a large taboo in our society, although it is a common problem that affects nearly 25% of the population. The oral cavity is the major origin of this “disease” (85%), followed by the ENT-area (10%) and several blood-born diseases (5%).

First the origin of the phenomenon will be discussed. It is explained that volatile sulphur components (e.g. H2S) and amines (e.g. cadaverine), produced by the anaerobic microflora in the oral cavity, are the main contributing fragrances.

Furthermore the different detection methods (subjective – organoletipcal / objective – Halimeter® and Oral Chroma®) will be highlighted.

Although gingivitis, periodontitis and mainly tongue coating are the principle oral causes, also dental implants can strongly contribute to breath odor problems. So furthermore, the origin of breath malodor due to implant-involved causes (e.g. peri-implantitis) will be presented.

Finally treatment approaches for all these different situations will be proposed and discussed.
