Odontogenic Infection
Pronunciation: oh-don-toh-JEN-ik in-FEK-shun
An infection originating from a tooth or its supporting structures, capable of spreading into adjacent fascial spaces of the head and neck.
Full Definition
Odontogenic infections arise from dental pulp necrosis, periapical abscess, periodontitis, or pericoronal inflammation, and may spread via defined anatomical pathways into deep fascial spaces such as the submandibular, parapharyngeal, or masticator spaces. In editorial review of oral surgery records, 'odontogenic' must be distinguished from 'non-odontogenic' infections of the jaw and neck, as the distinction affects both treatment pathway documentation and medico-legal accountability. The term 'odontogenic' is an adjective and should modify a noun (infection, cyst, tumour); it should not stand alone. Severity grading (e.g., localised abscess vs Ludwig's angina) must be clearly documented.
Usage
Usage note: 'Odontogenic' is an adjective only; do not use as a standalone noun. Ensure the causative tooth is identified and the fascial spaces involved are listed in operative and admission documentation.
