Fig.1: A 50-year-old man has mild pain in the upper left 1st bicuspid (#12) 3 years after root canal retreatment with placement of two posts. The tooth has periapical or periradicular radiolucency (<). Although the 2nd bicuspid has also radiolucency, percussion is more severe associated with #12 than #13. Exploratory surgery 4 months before extraction confirms root fracture.
