title: Detection of immune complexes in human dental periapical lesions by anticomplement immunofluorescence technique.
abstract: Twenty-five human dental periapical lesions were obtained. The lesions were frozen, sectioned, and examined for the presence of immune complexes by employing an anticomplement immunofluorescence (ACIF) technique. Twenty-three of the periapical specimens were positive for antigen-antibody complexes. No staining was noted in the two lesions that were histologically diagnosed as periapical scar tissue.
