The scope of the lecture includes aspects of orthodontic procedures, which result in the generation of aerosol. Emphasis is placed on the formulation and constituent components of aerosol, which include airborne bacteria/viruses and particulates arising from the grinding of enamel and dental composites. The multifaceted effects of this mixture of dissimilar entities involve:

hazards associated with the production of PM 2.5 aerosol particles for the respiratory function, which might inflict silicosis;
the contamination of the operatory with bacteria, which stay airborne for extended periods of time;
the production of potentially endocrine disrupting compounds (EDC) with direct effects on the hormonal homeostasis owing to the release of bisphenol A during grinding of the composite resins with rotary instruments.
The phenomena accompanying the placement and removal of composite resins and aligner attachments are reviewed and misconceptions or traditional beliefs are clarified. Along with the description of the effects induced and their potential health impact, a brief summary of evidence-based and empirically-derived guidelines to limit the undesirable effects associated with the use of rotary instruments in a dental setting is provided. To this end, a wide array of materials, processes, and apparatuses focusing on reducing, controlling or negating the potential hazardous effects relating to the infectious nature or biohazardous action of aerosol is presented.

He graduated from the School of Dentistry, National and Kapodistrian University of Athens, and completed his Orthodontic residency at the Ohio State University. He earned a Master of Science degree from Ohio State, a doctorate in medical sciences from the University of Athens, School of Medicine, a PhD in Biomaterials from the University of Manchester, where he was awarded a DSc degree.

His research has generated 250 papers in pubmed listed journals and 50 book chapters, which have received over 10,000 citations and an h index of 55 (google scholar). He has edited 13 textbooks published by major houses, some of which translated into 5 languages. He has co-supervised and/or examined 50 doctorate and Master theses at Universities from 7 countries on 4 continents, and is an elected Fellow of the Institute of Materials, Minerals and Mining, the Royal Society of Chemistry, and the Institute of Physics (UK). Prof. Eliades has been Visiting Professor at King’s College London, affiliated with institutions in the US and Europe (Texas-Houston, Marquette, Manchester and Bonn), and has served as the Editor-in-Chief of the Journal of Dental Biomechanics, Associate Editor of the European Journal of Orthodontics, the American Journal of Orthodontics and Dentofacial Orthopedics, and the Progress in Orthodontics. He was the 2015 Jan Taylor Visiting Lecturer of the Australian Foundation for Orthodontic Research and Education, and the 2018 Milton Sims Visiting Professor at the University of Adelaide. He served as a member of the task Force for harmonization of worldwide postgraduate orthodontic education of the World Federation of Orthodontists and the revised Erasmus guidelines committee for postgraduate orthodontic education in Europe (NEBEOP). Work under his supervision has received the Bengt Magnuson prize of the International Association of Pediatric Dentistry, the FEO award of the European Federation of Orthodontists, and thrice the WJB Houston research poster award of the European Orthodontic Society.

The area of his expertise include aspects of materials science relevant to clinical application of materials and treatment efficiency, retrieval analysis of biomaterials, biological properties of materials, dental hard tissues and bonding, and mechanics of materials and tissues. Since 2002 he manages the biomaterials network ( a research initiative comprised of European Universities and research centers.

Dear WFO Colleagues,

Whichever part of the world you are in, the WFO Executive Committees’ thoughts are with you all at this difficult time.

The WFO, as the umbrella organisation for our speciality is deeply concerned about the impact of the Covid-19 pandemic on all our professional and personal lives. We express particular concern for our patients – young and old – who are desperately waiting for a sense of normality in order to continue their treatment.

This year is momentous for the WFO as it is our Silver Jubilee – 25 years from inauguration on 15th May 1995.

We had great plans to be launched at the worldwide meetings this spring – sadly cancelled. But we can and will go forward with World Orthodontic Health Day (WOHD).

We would encourage you all to celebrate, by digital/virtual observance, both the WOHD and the Silver Jubilee on 15th May.

Resources – for your use – have been created on the WFO website WOHD page and social media channels (Facebook, Instagram, YouTube):

1. WOHD and Silver Jubilee E posters to be downloaded in high resolution.

2. WOHD and Silver Jubilee Virtual Backdrops for online meetings and photo opportunities.

3. Digital Smile Flag templates for Affiliate Associations, Fellows, Educational Departments to be used for E Banners on websites, web promotions and social media.

4. WFO Silver Jubilee Logos

Please post both on your social media and tag the World Federation of Orthodontists so your celebration may be shared with colleagues around the world.

We encourage the use of hashtags:

#theworlduntiteswhenpeoplesmile #WFO@25 #WFOSilverJubilee #WOHD2020

Please send images and screen shots of your WOHD activities to

We hope you will all join us to promote our wonderful speciality of orthodontics, the WFO and the WOHD.

Stay safe and healthy.

Kind regards,

Allan R. Thom
President, World Federation of Orthodontists
