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
Where does infection that has spread to the masseteric space originate from?
lower third molars
Where does infection that has spread to the pterygomandibular space originate from?
lower third molars
Where does infection that has spread to the lateral pharyngeal space originate from?
lower third molars
Where does infection that has spread to the lower lip originate from?
Mandibular incisors and canines
Where does infection that has spread to the submandibular space originate from?
Root apices below insertion of mylohyoid - usually molars but can also be premolars
Where does infection that has spread to the submental space originate from?
incisors and canines
Where does infection that has spread to the sublingual space originate from?
root apices above mylohyoid/geniohyoid - usually incisors, canines and premolars (rarely molars but depends on root positioning)
