A radicular (periapical) cyst is lined by epithelium derived from which embryologic source?
Show answer and explanation
Correct answer: A. Epithelial rests of Malassez
Radicular (periapical) cysts develop from proliferation of the epithelial rests of Malassez — remnants of Hertwig's epithelial root sheath that persist within the periodontal ligament after root formation is complete — stimulated by chronic periapical inflammation following pulp necrosis.
