Jens O. Andreasen, D.D.S.
Dr. Andreasen serves as an associate professor at the University Hospital in Copenhagen, Denmark. In 1959, he received his Doctor of Dental Surgery from the Royal Dental College in Copenhagen. He completeted his postgraduate training in oral and maxillofacial surgery at the University Hospital.
He has authored 308 publications and 10 textbooks covering topics such as dental traumatology, tooth replantation and autotransplantation, tooth eruption and tooth impaction. He has received four honorary doctorate degrees and has been invited to lecture in 44 countries.

Evidence-Based Treatment of Traumatic Dental Injuries
Topic: Traumatic Injuries Diagnosis & TreatmentLearning Objectives:
- Enable the participant to perform evidence-based dental trauma treatment, which optimizes periodental and pulpal healing.
- Make an early diagnosis of healing complications such as pulp necrosis and root resorption.
- Select effective treatment modalities to treat complications.
- Describe long-term treatment of autotransplantation of premolars or insertion of implants in an edentulous trauma site.
- Become acquainted with a new interactive dental trauma database.
Recent developments within diagnosis and treatment of traumatic dental injuries will be presented including:
- How to optimize pulp and periodontal healing after trauma.
- The influence of repositioning, splinting and antibacterial treatment.
- In which types of dental injuries are treatment delays acceptable?
- Optimal follow-up regimens for detecting pulp and periodontal complications, and which method is the most reliable in diagnosing pulpal and periodontal complications.
Acute and semipermanent restorations (composite).
Life expectancy of crown restorations and “weak points” in restoration.
Long-term results of fragment bonding.
Long-term results of forced extrusion, gingivectomy and intra-alveolar transplantation will be presented and compared.
An analysis of 500 root-fractured teeth is the basis for predictors of healing, including the effect of various splinting methods, splinting time and repositioning. Furthermore, the results of endodontic treatment of failure cases will be presented.
Extrusion and lateral luxation
Predictors for healing pulp and periodontal complications will be presented based on 200 analyzed cases.
In a recent study of 140 intruded permanent teeth, the healing outcome of three treatment modalities was analyzed including surgical repositioning, orthodontic repositioning and spontaneous repositioning. Predictors for the use of these three methods will be presented according to 15-year survival of the treated teeth.
Avulsion and replantation
Based on a long-term study of 400 replanted teeth analyzed up to 20 years after replantation, predictors for optimal healing will be presented such as extra oral storage conditions, splinting methods and endodontic interventions. Treatment suggestions based on a decision tree analysis will be presented.
Autotransplantation of premolars to replace resorbed or lost incisors
A recent study of 220 transplanted premolars to the anterior region and with a follow-up of up to 25 years has given important information about the bone-inducing capacity of this procedure, as well as the graft survival, and aesthetic and functional long-term results.
Implants used to replace resorbed or lost incisors
The result of 160 implants placed in the anterior region of adolescents and followed for 10-15 years will be presented, including implant survival, esthetic function and influence upon neighboring teeth.
Why trauma endodontics (TE) differs from conventional endodontics (CE), and how to optimize endodontic therapy after trauma will be discussed in this lecture along with the following aspects:
- The difference in the cause of pulp pathology (trauma ~ carries), including where bacteria are located in TE and CE (pulp, dentinal tubules, and periodontium).
- Natural progression of pulp and periodontal complications (root resorption) in TE and CE.
- Requirements for optimal healing in TE.
- Diagnosis of infection-related root resorption and replacement resorption (ankylosis).
- The importance of timing endodontic interventions in TE with relation to treatment success.
- A comparison between three different endodontic techniques upon the arrest of progressive root resorption (infection-related resorption and ankylosis). An analysis of 250 cases.
- The negative effect of Ca(OH)2 with special reference to the weakening of dentin leading to cervical fractures.
- Hard tissue-inducing effect of MTA (dentin and cementum formation), strengthening the effect of MTA in immature teeth. The combination of MTA and calcium hydroxide in the treatment of pulp pathology after trauma.
- The efficacy of various chemical and antibiotic regimens upon periodontal healing after replantation.
- When to give up treatment of resorbing traumatized teeth especially with reference to the loss of alveolar growth in adolescence.
