Copy of SEQULAE OF ODONTOGENIC INFECTIONS

  • Invading bacteria triggers inflammatory process
  • Streptococci-is found in  early days of infection(invades by production of streptokinase and hyaluronidase)
  • There is an exponential increase in streptococci-they create an enviornment for the anaerobic flora(as they consume local O2 & nutrients)
  • Anaerobes (prevoltella and porphyromonas)produce collagenase
  • After it perforates the bony cortical plate
  • It spreads to the most vulnerable tissue(areolar tissues)-since its not well vascularized,loose and dissected by low hydrostatic pressure
  • Infection spreads along the path of least resistance deflected by dense and vascularised structures
