Dr. Bollen graduated in 1992 as dentist at the Catholic University Leuven (Belgium). In 1996 he received his PhD at the same university. One year later he finished his specialisation in periodontology (MSc perio) under supervision of prof. dr. D. van Steenberghe. In 2016 he became MClinDent in esthetic and restorative dentistry (University of the Pacific, US).

Dr. Bollen published more than 30 scientific articles in peer reviewed international dental journals. He is editor in chief of the Journal of Dental Health, Oral Disorders & Therapy and editor of several online dental journals.

Curd Bollen leads a dental clinic in the Netherlands, limited to periodontology, implantology and halitosis. His research interests are: ceramic dental implants, halitosis and peri-implantitis.



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.
