Quantitation of circulating immune complexes, immunoglobulins G and M, and C3 complement component in patients with large periapical lesions.
The serum concentrations of circulating immune complexes, immunoglobulins G and M, and the C3 complement component of thirty patients with one to three large periapical lesions were measured and compared with those of patients with no periapical lesions. The results indicate that there is no statistical difference between the two groups, and it appears that chronic periapical lesions cannot act as a focus to cause systemic diseases via immune complexes.
