The immunologic diagnosis of chronic active "autoimmune" hepatitis: distinction from systemic lupus erythematosus.

We have evaluated the immunologic characteristics often associated with systemic lupus erythematosus in a series of patients with a variety of different liver diseases. Antibody to double-stranded DNA as measured by the Farr assay was detected frequently in patients with various forms of liver disease. No patient with liver disease, including those with a presumed immunologic etiology, was found to have antibody to double-stranded DNA using more specific assays. Other immunologic phenomena such as the presence of immunofluorescent staining at the dermal-epidermal junction in the lupus band test, circulating immune complexes and the presence of antinuclear antibody were present in a number of patients with different forms of liver disease. The absence of antibody to double-stranded DNA in patients with liver disease suggests that there may be a true immunologic distinction between systemic lupus erythematosus and chronic active ("lupoid") hepatitis.

Crown recontouring using a new polishable hybrid composite material.

Visible light cured hybrid composite materials are assuming an increasingly important role in esthetic dentistry because they offer the combination of a high degree of polishability together with clinically proven durability and fracture resistance. Further, some hybrid materials may be used both anteriorly and posteriorly. Thus they are termed "universal" composite materials. The purpose of this paper is to demonstrate two cases of esthetic conservative anterior crown reconstruction and a posterior composite restorative technique using a newly introduced polishable hybrid material (Prisma APH, L. D. Caulk Co., Milford, DE).

Gingivally submerged cervical erosion lesion--a clinical problem.

The technique used to treat cervical erosion lesions that are buried beneath the crest of the gingival tissue is described. With proper isolation of the field and careful gingival retraction as prerequisites, the surface topography of the completed restoration is almost indistinguishable from the adjacent enamel, and the gingival tissue response is good.
