Spread of Infection Flashcards
Where might infection of upper anterior teeth spread to?
- lip
- nasolabial region
- lower eyelid
Where might infection of upper lateral incisor spread to?
Palate (not very common)
Where might infection of upper premolars and molars spread to?
- cheek
- infra-temporal region
- maxillary antrum (very rare)
- palate (less common)
Where might infection of lower anteriors spread to?
mental and submental space
Where might infection of lower premolars and molars spread to?
- buccal space
- submassteric space
- sublingual space
- submandibular space
- lateral pharyngeal space
How is spreading infection managed?
- establishment of drainage
- removal of source infection
- antibiotic therapy
What are the intraoral features of Ludwig’s Angina?
- raised tongue
- difficulty breathing
- difficulty swallowing
- drooling
What are the extraoral features of Ludwig’s Angina?
- diffuse redness and swelling bilaterally in submandibular region
What is Ludwig’s Angina?
Bilateral cellulitis of the sublingual and submandibular spaces
What are the systemic features of Ludwig’s Angina?
- increased HR
- increased respiratory rate
- high temperature
- high white cell count
Where does infection that has spread to the palate originate from?
Maxillary teeth = Palatal roots of premolars and molars (also lateral incisors with a palatally curved root)
Where does infection that has spread to the buccal space originate from?
Maxillary = canines, premolars, molars
Mandibular = canines, premolars, molars
Where does infection that has spread to the infraorbital/periorbital region originate from?
Maxillary canines mainly
Where does infection that has spread to the maxillary sinus originate from?
Maxillary = canines, premolars and molars
Where does infection that has spread to the upper lip originate from?
Maxillary = central & lateral incisors
