Researchers from Erasmus University publish findings in Life Sciences
2007 OCT 18 -- According to a study from Netherlands, "Temporomandibular joint (TMJ) involvement is a frequent feature in cross-sectional prevalence studies among juvenile idiopathic arthritis (JIA) patients. The cross-sectional design makes it almost impossible to study the incidence." "Follow-up data on TMJ involvement are sparse. In this study patients were reviewed with an interval of a minimum of I year and a maximum of 2 years to study the yearly incidence of TMJ involvement and to obtain follow-up data on TMJ involvement and orthopantornogram (OPT) alterations. Children with JIA from a previous study on TMJ involvement were included. OPTs were scored according to Rohlin's grading system (grade 0-5). A paediatric rheumatologist measured the level of disease activity during the interval. Eighty-nine of the 97 patients were included in this study with a mean follow-up of 14 months. The yearly incidence of TMJ involvement was 7.1% in patients with JIA. Improvement on the OPT was seen in 27 patients (66%), and 19 of these patients no longer showed any signs of TMJ involvement. Worsening on the OPT was seen in four patients (10%). Disease activity was significantly lower in the improved patients than in the patients with worsening. Condylar lesions due to arthritis can improve over time, indicating a regenerative capacity of the mandibular condyle," wrote M. Twilt and colleagues, Erasmus University. The researchers concluded: "As condylar improvement seems to be associated with low disease activity, it is important to consider the TMJ when deciding on a therapeutic regimen." Twilt and colleagues published their study in Scandinavian Journal of Rheumatology (Incidence of temporomandibular involvement in juvenile idiopathic arthritis. Scandinavian Journal of Rheumatology, 2007;36(3):184-188). For more information, contact M.
