Endodontic Infection Flashcards
summarise the immune response in endodontic infections
macrophages attracted due to LPS and cytokines which migrate to apex
present antigens to adaptive immune cells such as T cells and B cells
what are the key bacteria in endodontic infections
enterococcus faecalis
porphyromonas endodontalis
what type of bacteria is enterococcus faecalis
anaerobic gram positive rods
is a primary or secondary endodontic infection more likely to contain e faecalis and why
secondary
predominantly gram positive microorganisms whereas primary endo infections are more gram negative
what are the virulence factors of e faecalis
endotoxins
adhesins
collagenases
hyaluronidase
immune evasion
what are the management considerations for endodontic infections
sodium hypochlorite and EDTA
either mechanically manage via RCT or you can remove the root
what is the best way to treat a mono species infection
sodium hypochlorite and EDTA together
what is the impact of yeast of endo infections
it supports bacterial growth and propels bacteria down the dentine tubules
