2017 WHO histological classification of odontogenic and maxillofacial bone tumours lays out a classification system for neoplasms and other tumours related to the odontogenic apparatus.

Classification

Malignant odontogenic tumours

odontogenic carcinomas
- ameloblastic carcinoma
- primary intraosseous carcinoma, not otherwise specified
- sclerosing odontogenic carcinoma
- clear cell ~~ondotogenic~~odontogenic carcinoma
- ghost cell odontogenic carcinoma
odontogenic carcinosarcoma
odontogenic sarcomas

Benign odontogenic tumours

benign epithelial odontogenic tumours
- ameloblastoma
  - ameloblastoma, unicystic type
  - ameloblastoma, extraosseous/peripheral type
  - metastasising ameloblastoma
- squamous odontogenic tumour
- calcifying epithelial odontogenic tumour
- adenomatoid odontogenic tumour
benign mixed epithelial and mesenchymal odontogenic tumours
- ameloblastic fibroma
- primordial odontogenic tumour
