Odontogenic Cysts and Tumors

Odontogenic Cyst

Radiolucent lesion associated with tooth development.

Corticated Border

Radiopaque line surrounding a well-defined lesion.

Punched Out Appearance

Indicates rapidly growing lesions, suggest malignancy.

Pericoronal Location

Lesions located around the crown of teeth.

Lateral Periodontal Cyst

Cyst along the lateral root surface of teeth.

Periapical Granuloma

Inflammatory lesion at the apex of a tooth.

Dentigerous Cyst

Cyst surrounding the crown of an unerupted tooth.

Odontogenic Keratocyst (OKC)

Cyst with high recurrence and growth potential.

Nevoid Basal Cell Carcinoma Syndrome

Genetic condition linked to multiple odontogenic keratocysts.

Orthokeratinized Odontogenic Cyst (OOC)

Cyst with orthokeratotic epithelial lining.

Gingival Cyst of the Adult

Cyst without minor salivary glands in alveolar mucosa.

Calcifying Odontogenic Cyst

Cyst with radiopaque structures in some cases.

Glandular Odontogenic Cyst

Cyst with a predilection for the mandible.

Ameloblastoma

Aggressive benign odontogenic tumor, multilocular radiolucency.

Malignant Ameloblastoma

Rare, aggressive variant found in lungs.

Clear Cell Odontogenic Carcinoma

Ill-defined margins on radiographic examination.

Adenomatoid Odontogenic Tumor

Tumor associated with the crown of impacted teeth.

Calcifying Epithelial Odontogenic Tumor

Tumor with amyloid-like material and concentric calcifications.

Ameloblastic Fibroma

Benign tumor commonly found in children.

Odontoma

Developmental anomaly with tooth-like structures.

Compound Odontoma

Recognizable tooth-like structures in radiographs.

Complex Odontoma

Haphazardly arranged calcified mass without tooth resemblance.

Odontogenic Myxoma

Large, painless expansion with thin bone trabeculae.

Differential Diagnosis for Multilocular Radiolucency

MACHO: Includes odontogenic myxoma, ameloblastoma, and others.

Pericoronal Unilocular Radiolucency

Commonly associated with dentigerous cyst in adults.

Buccal Bifurcation Cyst

Rare cyst with characteristic root apex tipping.

Residual Cyst

Periapical tissue remaining post tooth extraction.
