CURRICULUM VITAE

Spyridon Papageorgiou is a faculty member at the Clinic of Orthodontics and Pediatric Dentistry, Center of Dental Medicine of the University of Zurich in Switzerland. He graduated from the Dental School in the Aristotle University of Thessaloniki in Greece, while he completed his orthodontic specialty training and his doctorate (Summa Cum Laude) from the University of Bonn in Germany. He has published over 100 papers in international peer-reviewed scientific journals and over 10 chapters (h-index: 21; i10-index: 37), acts as a reviewer for 30 journals, and acts as academic editor in two journals. He has co-supervised or examined over 10 theses or dissertations at Universities from 3 countries. He worked on basic science, clinical trials, and evidence-based research funded by the German Research Foundation (2013), the Greek & German State Scholarship Foundations (2015), and the European Orthodontic Society (2016). His work has received multiple awards, including the David L. Turpin Award for Evidence-Based Research (2012) and the B.F. and Helen E. Dewel Award for Clinical Research (2018) from the American Association of Orthodontists, the Chapman Prize (2018) from the British Orthodontic Society, and the Best Research Award (2015) from the Greek Orthodontic Society. His research focuses on the clinical outcome, duration, or side-effects of orthodontic treatment, evidence-based methods to identify bias in orthodontic clinical research, open / transparent research practices, and biomechanical orthodontic investigations with the finite element method.

ABSTRACT

Orthodontic treatment and compromised periodontal tissues: a review of the evidence

Orthodontic treatment with fixed appliances has become an integral part of contemporary orthodontics, but has been associated with certain adverse effects to the periodontium, which are generally thought to be transient and not related to any lasting tissue damage. These include increased clinical plaque and bleeding indices, enlargement of gingival pockets, marginal bone loss, and quantitative or qualitative changes in the oral microbiota. Orthodontic treatment-induced microbial changes can be attributed to the plaque-retentive characteristics of orthodontic appliances, whilst deepening of the gingival crevice through hyperplasia might additionally offer a favorable environment for periodontopathogenic anaerobic bacteria. Overall, these conditions contribute to the fixed appliance treatment phase posing a potential threat to the health of the periodontal tissues. The current presentation will present in an evidence-based manner data from high-quality clinical studies in humans on the effect of orthodontic treatment with fixed appliances on periodontal health and provide recommendations for clinical practice and future research.
