The rôle of immunological reactions in apical cyst formation and the fate of epithelial cells after root canal therapy: a theory.
نویسنده
چکیده
Activation of the epithelial cell rests of Malassez by various means, results in proliferation of these cells and formation of apical periodontal cysts. Several theories for the genesis of apical periodontal cysts have been suggested which are not satisfactory. Available evidence indicates that development and destruction of these lesions are mediated by immunological reactions.
