Thomas Klit Pedersen, DDS, is clinical professor and consultant orthodontist in the field of growth-conditioned deformities of the jaws at the Department of Oral and Maxillofacial Surgery, Aarhus University Hospital and Section of Orthodontics, Faculty of Health Sciences, Aarhus University, Denmark. He is responsible for the Clinic for Dentofacial Anomalies managing patients with juvenile idiopathic arthritis (JIA) and similar temporomandibular joint (TMJ) conditions. He finished his orthodontic training in 1991 and completed his Ph.D. on the treatment of patients with JIA in 1996.
His research interests are TMJ arthritis and pathology and its consequences for craniomandibular growth, treatment of these conditions, cytokine levels in the TMJ, effect of inflammatory modifying drug injections, distraction osteogenesis, orthognathic surgical procedures i.e. surgery first, orthopaedic and surgical treatment of dentofacial anomalies and cleft lip and palate, the use of skeletal anchorage and virtual surgical planning. He is clinical instructor in the postgraduate education, mainly on orthognathic surgical patients and patients with orofacial issues.
He is a member of the board and co-founder (since 2008) of TMJaw (Temporomandibular Joint in Juvenile Arthritis Workgroup), an international research network on TMJ arthritis in JIA patients and subsequent dentofacial deformities.
Juvenile idiopathic arthritis – an interdisciplinary update
Temporomandibular joint (TMJ) arthritis is a well-known complication in juvenile idiopathic arthritis (JIA), with a prevalence of about two-thirds of patients affected, dependent on terminology, clinical examination standards, methods used for diagnostics and imaging techniques. TMJ arthritis can cause growth disturbances and development of severe dentofacial deformities. Furthermore, the overall impact, related to orofacial abnormalities, results in temporomandibular disorders, frequently shown to be a permanent condition, following the patients into adulthood. Other pathologic conditions in the TMJ often hamper the diagnosis of JIA related TMJ arthritis and even the diagnosis of JIA can be difficult in cases of isolated TMJ arthritis. Although evidence for the effect of treatment for TMJ arthritis and the orofacial consequences is sparse, some recommendations exist. Treatment of these conditions is known to need a multidisciplinary coordinated effort.
The lecture will emphasize the contemporary terminology, recommended diagnostic tools and treatments options related to TMJ arthritis in patients with JIA. Furthermore, the difficulties in TMJ diagnosis will be discussed in the context of other pathologic conditions of the TMJ.
Aim, Objectives & Learning Outcomes
- Aim: To describe the contemporary terminology, recommended diagnostic tools and treatments options available for TMJ arthritis in patients with JIA and to highlight TMJ diagnosis in the context of other pathologic conditions.
- Objectives: To illustrate the complexities of managing TMJ arthritis in JIA and other related conditions and to give practitioners guidance on the management options available.
- Learning outcomes: Following this presentation, attendees should have contemporary knowledge about TMJ arthritis in JIA and be able to advise these patients of the management options which exist and know how to explore these appropriately for their patients.
