Teeth nerve supply and surrounding tissues Flashcards
What are the main branches and the nerves off the Facial nerve supplying nerve supply to teeth and surrounding tissues
V2- maxillary teeth via Posterior superior alveolar/middle superior alveolar and anterior superior alveolar nerve forming the dental plexus
V3 - interior alveolar nerve and its Incisive branch forming the dental plexus to the mandibular teeth
However surrounding tissues are also involved with CN VII,IX,X and XII
What does the Buccal nerve of V3 supply
Supplies Buccal gingival/mucobuccal fold area in the mandibular molar region
Does the buccal nerve of V3 supply buccinator
No - lies on it and pierces it but not supply it ( via buccal nerve VII-facial nerve )
What does the lingual nerve of V3 supple
Gingivia /mucous membrane lingual side mandible
Anterior 2/3 tongue-taste and general sensation
Mucous membrane floor mouth
Where do the mental and incisive nerves originate from off inferior alveolar nerve
At the mental foramen
What does the incisive nerve off inferior alveolar nerve supple
Pulpal tissue / Periodontal ligament /bone of the - mandibular 1st premolar/canines/incisors
What does the mental nerve off V3 supply
skin chin and lower lip mucous membrane
Where does the inferior alveolar nerve originate and travel
Off the V3 mandibular branch once it exits foramen oval travels thru the mandibular canal -exiting at the mandibular foramen .
Continues then divides into mental /incisive nerve as it enters the mental foramen
What does the inferior alveolar nerve supply
Forms part of the dental plexus - to mandibular posterior teeth
Supplies plural tissues /periodontal ligament /bone of mandibular posterior teeth UP TO MENTAL FORAMEN where it becomes the incisive nerve/mental nerve ( incisive Nerve then supplies other mandibular teeth as part of the dental plexus )
