title: The influence of stabilisation appliance therapy and other factors on the treatment outcome in patients with temporomandibular disorders of arthrogeneous origin.
abstract: The aim of this study was to investigate if the difference in treatment outcome between patients provided with a stabilisation appliance and a control appliance was due to the treatment and/or other factors in patients with temporomandibular disorders (TMD) of arthrogeneous origin. Sixty patients were assigned to two equally sized groups: a treatment group, treated with a stabilisation appliance, and a control group given a control appliance. Thirteen possible background variables for the treatment outcome were correlated to changes in severity of temporomandibular joint (TMJ) pain on a verbal scale in the two patient groups. The logistic regression analyses revealed that, after correcting for the background variables, stabilisation appliance treatment was a strong explanatory factor for a positive treatment outcome, with a significance of P = 0.0013 compared to patients belonging to the control group. Background variables of significant importance for the treatment outcome were male sex (positive) (P = 0.0268), and severe or very severe TMJ pain (negative) (P = 0.0034). These findings indicate that not only the treatment with a stabilisation appliance but also sex and the intensity of the TMJ pain before treatment might influence the treatment outcome in patients with TMD of arthrogeneous origin.
