What is the First Line of defense against infection?
The IMMUNE System
(Adjunctive lines of defense against infection include removal of source (I&D), antibiotics)
When should antibiotics be considered?
1. When infection goes beyond localized stage and Progresses into Soft Tissue (swelling, collection of purulence under tissue) or patient exhibits Systemic Signs and Symptoms
2. With acute odontogenic infection - almost always involving Gram + Cocci (alpha-strep) & 4-6 anaerobes
3. If patient shows no improvement/worse in 72 hours
What type of bacteria are found in acute odontogenic infections?
Gram + Cocci (alpha-strep)
4-6 anaerobes
What is the first drug of choice for acute odontogenic infections (almost always involving Gram + cocci & 4-6 anaerobes)?
(Augmentin {amoxicillin + clavunate} can be given if infectino is severe at presentation [wider spectrum])
What should you do if a patient with an odontogenic infection shows no improvement or gets worse in 72 hours?
1. Culture infection
2. Consider switching antibiotics to Clindamycin while you wait for the culture
What type of antibiotic is preferred, Bacteriocidal or Bacteriostatic?
Bacteriocidal - stronger, better patient compliance (because if patient misses a dose, bacteria that have been killed stay dead vs. cyclic return of bacteria if pt is taking a bacteriostatic drug)
When treating infection with antibiotics you should start with narrow spectrum and work your way to broad spectrum.
