Lars Andersson

Keynote lecture - Saturday, May 21, 2022

About author:

Dr Andersson completed undergraduate and research training at the Karolinska Institute in Stockholm, Sweden and subsequently became Specialist in Oral and Maxillofacial Surgery in 1981. He defended his doctoral thesis in 1988 on experimental and clinical studies on root resorption after replantation of teeth. He was appointed Docent at Karolinska Institute, Stockholm, Sweden in 1990. In the 1990s he chaired a national specialist training program in Oral and Maxillofacial Surgery in Sweden. During the period 2002-2017 he was Professor in Oral and Maxillofacial Surgery at Kuwait University in Kuwait and from 2017 Senior Professor in Oral Maxillofacial Surgery at Malmö University, Sweden. He has published more than hundred articles in international Medline indexed scientific journals. Dr Andersson has been textbook editor of four textbooks and chapter author in several textbooks. He was Editor-in-Chief of the internationally renowned scientific journal, Dental Traumatology from 2007-2015 and was President of the International Association of Dental Traumatology 2011-2014.


Abstract of the lecture:

Root resorption is sometimes seen after autotransplantation of teeth. While infection related root resorption today can be prevented or treated, ankylosis is still considered to be the most serious long term complication for the tooth resulting in progressive replacement resorption of the root and eventually causing loss of the tooth. Moreover, inhibition of growth and development of the alveolar process is also seen in young growing patients following ankylosis. The lecture will give a complete overview aiming at understanding the development, progression and management of ankylosis based on in vivo- and clinical studies and an overview of the literature. An overview of various less successful methods to manage ankylosis will be given and the method of choice today, decoronation, will be presented. The recent shift in paradigm from “save the tooth” to “preserve the bone” will be elucidated.
