Q
  • Accumulation of acute inflammatory cells at the apex of a non-vital tooth
  • May arise as the initial periapical pathosis or as an acute exacerbation of chronic periapical lesion (Phoenix abscess)
  • Generally symptomatic but. may be asymptomatic if there is a lack of accumulation of purulent material due to a chronic path of drainage
