| Research Abstract |
Radicular cyst is one of the periapical lesion, their formation is associated with the proliferation of epithelial cell rests of Malassez. However, little is currently known about the precise mechanisms of formation and enlargement of radicular cysts. The purpose of this study is to examine the levels of antimicrobial activities of periapical lesions, therefore, we evaluate the levels of antimicrobial peptide (AMP) and E-cadherin in periapical lesion and dental epithelial cell lines. These observations suggest that dental epithelial cells can secrete AMPs and consolidate epithelial intercellular junctions when stimulated by bacterial infection,and radicular cysts may play an important role in defense mechanisms.
