early infection duration - CORRECT ANSWER - less than 3 days of symptoms
-strep viridians
late infection duration - CORRECT ANSWER - more than 3 days
-staph aureus
,What are the 3 stages of odontogenic infections? - CORRECT ANSWER - 1) inoculation
2) cellulitis
3) abscess
Duration of inoculation phase of odontogenic infection - CORRECT ANSWER - 0-3 days
duration of cellulitis phase of odontogenic infection - CORRECT ANSWER - 2-5 days
duration of abscess phase of odontogenic infection? - CORRECT ANSWER - 4-10 days
What stage of odontogenic infection has severe and diffuse pain - CORRECT ANSWER -
cellulitis
what stage of odontogenic infection has pus present? - CORRECT ANSWER - abscess
what stage of odontogenic infection has red - CORRECT ANSWER - cellulitis, abscess
(periphery)
Bacterial species of Inoculation stage of odonto infection? - CORRECT ANSWER -
aerobic (more surface level)
Bacterial species of cellulitis phase of odontolo infection? - CORRECT ANSWER - mixed
(going in deeper, from aerobic-->anaerobic)
Bacterial species of abscess phase of odonto infection? - CORRECT ANSWER -
anaerobic (as it digs deep)
, What is most frequently isolated bacteria among aerobes? - CORRECT ANSWER -

Define difference between acute and chronic periapical abscess - CORRECT ANSWER --
acute: symptomatic. Red, swelling, DIFFUSE, fluctuant, paint
-chronic: asymptomatic. Localized swelling, fistula formation, pain subsides with pus drainage
sequelae (consequences) of periaplical abscess/ cellulitis - CORRECT ANSWER --
Ludwigs angina

At what ANC does patient risk for infection increase? at what ANC should we avoid
bacteriostatic drugs? - CORRECT ANSWER - risk increase with ANC below 1500
cells/mm^3
AVOID BACTERIOSTATIC DRUGS WITH ANC LESS THAN 500
ANC - CORRECT ANSWER - absolute neutrophil count (in cells/mm^3)
bacteriostatic vs bactericidal drugs
