My name is Johannes-Simon Wenzler. I am Senior doctor and lecturer in the Clinic for Restorative Dentistry, Periodontology and Preventive Dentistry at the University Hospital RWTH Aachen. You will get to know me at the latest within Module 5: Aesthetics, Function and Emergency Management and Module 8: Lasers in Periodontal Therapy with some of my very appreciated colleagues. I myself have been working in the clinical and scientific field for a few years, with a lot of passion, especially in the field of endodontology and periodontology, and I am focusing on the periodontal-endodontic interface. I am looking forward to a lively exchange and many new ideas in our master’s program.
