Abstract

Background: Interleukin-1 (IL-1) is one of the cytokines produced by macrophages, monocytes and
dentritc cells. Macrophages are present in apical granuloma and the wall of the radicular cyst. This
cytokine causes the cyst expansion and is involved in proliferation of fibroblasts in the cyst wall and
stimulate the fibroblasts to produce more prostaglandin. Radicular cyst is the most common cyst of the
jaws which is usually associated with necrotic pulp of the tooth. The cyst formation requires
proliferation of the epithelial rest cells of Malassez present in the periodontal ligament. Proliferation of
epithelial rest cells of Malassez is an essential event in the Pathogenesis of radicular cyst. Objective of
the study was to investigate the effect of IL-1 on epithelial cell proliferation which is an important
factor in the pathogenesis of radicular cyst. Methods: The cyst walls of 20 radicular cysts were
removed and were cultured in vitro to grow the epithelial cells. The culture were rapidly contaminated
and dominated by growth of fibroblasts. Therefore another cell line was used for the experiments.
Results: The result showed that proliferation was stimulated with increased in a biphasic manner with
maximum stimulation at 1.25 ηg/ml, beyond this concentration proliferation was decreased.
Conclusion: IL-1 had a proliferative effect on epithelial cells at low concentrations which may be
playing a role in evoking an inflammatory reaction and stimulating the epithelial cell rests of Malassez
to proliferate to form radicular cyst.
Keywords: Interleukin-1, radicular cyst, epithelial cell rests of Malassez, Epithelial cell proliferation
