Erythema nodosum is the most frequent clinicopathologic variant of panniculitis. Triggers are represented by infections, sarcoidosis, rheumatologic diseases, inflammatory bowel disease, medications, autoimmune disorders, pregnancy and malignancy. Erythema nodosum typically manifests by the sudden onset of symmetrical, erythematous, warm nodules, usually located on the lower limbs. Often the lesions are bilaterally distributed. Treatment of erythema nodosum should be directed to the underlying associated condition, if identified. Usually, nodules of erythema nodosum regress spontaneously within a few weeks, and bed rest is often sufficient treatment. Nonsteroidal antiinflammatory drugs and potassium iodide may be helpful drugs to enhance analgesia and resolution. Systemic corticosteroids are rarely indicated in erythema nodosum and before these drugs are administered, an underlying infection should be ruled out.

Purpose. The purpose of this study is to compare results and establish the accuracy of clinical and radiological examination methods forcervical limit of fi xed prosthetic restorations. Material and method. On the study was used one metal-ceramic crown and two metal crowns (a total of three crowns). Prosthetic abutments were made of light-cured composite resin, using the direct method within crowns. To obtain the spacing in the cervical area – with a value of 30 microns – were used aluminum foil with known thickness (30 microns) interposed between each abutment and each crown. 24 of X-ray were made: three X-rays for each corresponding value of 30 microns which was made interpretations (0 = perfect, 30, 60, 90, 120, 150, 180 and 210 microns). Radiographs were obtained by a standard method. Clinical examination consisted in placing crowns on each demonstration model (Frasaco); assessment was performed pre-established and marked points on each crown (four positions in the cervical area) for each of 30 microns. Radiological examination consisted in tracing the proximal cervical areas for each of 30 microns. Subsequently a total of 40 physicians evaluated crowns and radiographs without knowing the values used for testing. The results were recorded on forms. Results and conclusions. The result can be correlated on every value of radiological and clinical evaluation, except the value of 60 microns which appear to be clinically acceptable, but not radiological.
