On behalf of the Conference Organizing and Scientific Program Committees, we extend an enthusiastic welcome to the delegates to the 20th World Congress on Dental Traumatology. The International Association of Dental Traumatology and the American Association of Endodontists have joined forces to hold the most comprehensive, wide-ranging and educationally diverse conference on dental trauma ever held anywhere in the world. The Program Committee has done a superb job in molding the 4 days of the conference into an in-depth exploration of the life cycle of dental traumatic injuries starting with the initial injury and extending all the way through to multi-decades follow up. Using a variety of educational venues and methods, including keynote and concurrent speakers, small group discussions led by internationally renowned experts, workshops, an Educators Forum and competitive oral research, case reports, and posters, the field of dental trauma will be presented as never before for the practitioner, student, and educator. A host of vendors and exhibitors will provide the delegates with a wide array of the latest equipment, armamentaria, clinical materials and educational media to meet the clinician’s needs for the latest diagnostic and treatment modalities for the dental trauma patient. On the social side, two informal receptions and an evening Gala Dinner Cruise around San Diego Harbor, featuring first class cuisine, entertainment, and great vistas, will enhance collegial interaction and enjoyment. We hope you will take full advantage of this truly unprecedented opportunity in one of the most entrancing cities in the United States to join your colleagues in gaining a storehouse of knowledge and knowhow to better serve the dental trauma patient.
