Clinical considerations Flashcards
The single most important structure that restricts infection spread from the head to the neck
Hyoid bone
What is Pericoronitis
Infection of the gingiva overlaying A partially arrested or severely broken down tooth. Most common in their molars. Debris packed between the mucosa and the tooth promote rapid bacterial growth
What is characteristic of sublingual space infection or abscess?
The sublingual abscess is deep to the mylohyoid muscle.
What is characteristic of a submandibular space infection?
The abscess or infection is superficial to the mylohyoid muscle
Buccal space infection can spread to?
Why are they so dangerous?
Infraorbital
periorbital
Superficial temporal
Dangerous because they can spread the orbit and then to the cavernous sinus.
What does lewd wigs angina effect?
Bilateral perimandibular space infection, which compresses upper airway.
May spread to pretracheal space and become fatal
Which spaces allow infections in the oral cavity too spread to the mediastinum?
Retropharyngeal and Alar danger spaces
High severity infection Spaces.
- Lateral Pharyngeal
- Retropharyngeal
- Pretracheal
- Danger Space
- Mediastinum
Low Severity infection spaces
Buccal
Vestibular
infraorbital
MSA Injection is where?
Vestibule Near first and second pre molars
ASA/ IA Injection is where?
Vestibule deep up near the infraorbital foramen
Greater Palatine/ Incisive Injection is where?

Division 2 Block given where?

IA Injection
Lateral of Pterygomandibular raphe in the triangle
Long Buccal Injection given where
