Odontogenic
Pronunciation: oh-don-toh-JEN-ik
Arising from or relating to the tissues that form teeth; used to classify cysts, tumours, and infections that originate from tooth-forming epithelium or mesenchyme.
Full Definition
The adjective 'odontogenic' describes pathological entities — principally cysts, benign tumours, and malignant neoplasms — whose origin lies in the epithelial or ectomesenchymal remnants of the tooth-forming apparatus. Common examples include the odontogenic keratocyst (OKC), dentigerous cyst, and ameloblastoma. In clinical report writing, editors must use 'odontogenic' precisely; it is not synonymous with 'dental' (which may refer to any dental structure or procedure) nor with 'periapical' (which describes location around the root apex). The term also appears in the context of odontogenic infection, referring to spread of infection from a dental source.
Usage
Usage note: Do not substitute 'dental' for 'odontogenic' in pathology contexts; the terms are not interchangeable.
