Human periapical lesions develop as a result of a pathological immune response to continuous stimuli from infected root canals. This study identified the immunocompetent cells in such lesions immunohistochemically and quantified them to examine their interrelationships and correlations with clinical findings. The number of IgG-containing cells in CD4+ cell (Th/i)-rich lesions (> or = 55 CD4+ cells/2 x 10(4) microns 2) was significantly larger than in CD4+ cell-poor lesions (< 55 CD4+ cells/2 x 10(4) microns 2). This indicated that the CD4+ cells and the IgG-containing cells acted together against antigenic stimuli. The proportion of T cells in the mononuclear infiltrates varied with the size of the periapical lesions. The proportion of CD11+ cells (monocytes/macrophages) was significantly larger in lesions which showed a positive reaction to percussion or were tender on palpation than in the lesions without these symptoms. These observations suggest that T cells may play an important role in the development of periapical lesions and that CD11+ cells may be involved in the development of symptoms.
