Etiology • Stimulus unknown • Dental lamina remnant proliferation within the alveolar
segment of the jaw, separate from the periodontal ligament
Clinical Presentation • Asymptomatic • Usually occurs in fourth decade and beyond • Usually in mandibular canine/premolar region (65%) • In the maxilla, the lateral incisor area predominates.
Radiographic Findings • Well delineated, round to ovoid lucency with thin, opaque
(corticated) margin • Located lateral to vital tooth roots • Usually unilocular; may be multilocular (botryoid odontogenic
cyst)
segment of the jaw, separate from the periodontal ligament
Clinical Presentation • Asymptomatic • Usually occurs in fourth decade and beyond • Usually in mandibular canine/premolar region (65%) • In the maxilla, the lateral incisor area predominates.
Radiographic Findings • Well delineated, round to ovoid lucency with thin, opaque
(corticated) margin • Located lateral to vital tooth roots • Usually unilocular; may be multilocular (botryoid odontogenic
cyst)
Diagnosis • Thin, nonkeratinized epithelial lining • Nodular epithelial thickening along cyst lining • Lining cells are cuboidal with interspersed clear glycogen-filled
cells.
Differential Diagnosis • Inflammatory, lateral radicular cyst • Primordial cyst/odontogenic keratocyst • Odontogenic tumor • Glandular odontogenic cyst
Treatment • Conservative enucleation • The botryoid variant requires more aggressive curettage.
Prognosis • Recurrence uncommon • Increased risk of recurrence with botryoid variant; longer-term
follow-up necessary
