Abstract

Numerous studies have been focused on the immunologic aspects of inflamed pulp and periapical tissues. The purpose of this study was to evaluate levels of serum IgG and IgM in patients of acute pulpitis and acute apical abscess using Enzyme-Linked Immunosorbent Assay. Streptococcus mutans, Streptococcus sanguis, Bacteroides intermedius and Bacteroides gingivalis were grown for use as antigen and they were harvested by centrifugation. The patients were divided into 3 groups; patients of acute apical abecess, acute pulpitis and normal control 5 patients of each group were selected and their blood was obtained via intravenous puncture. Sera were prepared by centrifugation of each blood samples. Then serum antibodies were measured by modified ELISA. The following results were obtained; 1. Serum IgM levels of patients with acute pulpitis and acute apical abscess seemed to be slightly higher than those of normal control 2. Serum IgG levels of patients with acute apical abscess were slightly higher than those of normal control 3. Serum IgG and IgM levels of acute apical abscess patients and serum IgM levels of acute pulpitis were highest to Bacteroides gingivalis.
