Correct answer: E — Lateral periodontal cyst
The lateral periodontal cyst arises from remnants of the dental lamina (rests of Serre) — the epithelial strand that connects the developing tooth germ to the oral epithelium during embryonic development. It typically presents as a small, well-defined, round radiolucency on the lateral surface of a vital tooth root, most commonly in the mandibular premolar/canine region. The botryoid odontogenic cyst is the polycystic (multilocular) variant. Treatment is conservative enucleation with low recurrence. Radicular cysts arise from epithelial rests of Malassez; dentigerous cysts from reduced enamel epithelium.
