What does IDN stand for?
Inferior alveolar nerve. Also known as the inferior dental nerve. It’s a branch of the mandibular nerve which is a branch of V3. (3rd branch of trigeminal nerve)
What innervates the anterior palatal gingivae?
The nasopalatine nerve.
What innervates the posterior palatal gingivae?
The greater palatine nerve.
What innervates the maxillary anterior teeth?
The anterior superior alveolar nerve.
What innervates the maxillary premolar teeth?
The middle superior alveolar nerve.
What innervates the maxillary posterior teeth?
The posterior superior alveolar nerve.
What innervates the maxillary anterior buccal gingivae?
The infra-orbital nerve.
What innervates the maxillary posterior buccal gingivae?
The posterior superior alveolar nerve.
What innervates the mandibular anterior buccal gingivae?
Mental branch of the IDN.
What innervates the mandibular posterior buccal gingivae?
Buccal nerve.
What innervates the mandibular anterior teeth?
Incisive nerve of the IDN.
What innervates the mandibular posterior teeth?
Molar branch of the IDN.
What innervates the mandibular lingual gingivae?
The lingual nerve.
How does a dental infection spread?
- Direct local spread – muscle/fascial planes contain spread always path of least resistance
- Lymphatics (e.g. sub-mand/mental to deep cervical chain)
- Veins (cavernous sinus thrombosis)
What is a facial abscess?
Localised area of inflammation, contains pus – fluid. Use two fingers to detect movement of fluid - Fluctuance.
