answer key says that acute apical periodontitis is the correct answer. why??

yes, it is correct because for nonvital tooth bleaching, we use hydrogen peroxide and sodium perborate.......which can go to periapical area.....if the obturation is not complete.....can cause inflammation right up there.....an d therefore can cause acute apical periodontitis....which is acute inflammation of peridontium .....periodontal ligament, bone and cementum.
In later stages it can cause external root resorption, but not acutely or immediately.
Please correct me if I am wrong!

Because acute apical periodontitis is a collection of pus in the alveolar bone following pulp death with extension of the infection in the periapical tissue usually in improperly done rct I hope it helps! please post your questions in the NBDE part 2 questions thread!
