My name is Holger Jentsch from Leipzig. Here I have been the head of the centre for periodontology for more than 20 years. I am now an emeritus for some months. I worked clinically and scientifically in different fields of periodontology, e. g. subgingival instrumentation with a broad spectrum of adjunctive procedures and substances like hyaluronic acid or antibiotics, relationship of nutrition and periodontal disease as well as regenerative therapy.

Clinical and scientific work is ongoing, new scientific results can be expected. I have been a member of the board of the German Society of Periodontology (DG PARO), here I have been also the General secretary for two election periods.
