Apical periodontal cyst arise from Epithelial cell rest of malassez

Apical periodontal cyst arise from:

  • a. Hertwig sheath.
  • b. Epithelial cell rest of malassez.***

Apical periodontal cyst= periapical cyst = radicular cyst: these inflammatory cysts derive their epithelial lining from the proliferation of small odontogenic epithelial residues (rests of Malassez) within the PDL.
