a 21 year old female presents with slight discomfort on tooth #7 .she complains that it is tender o biting and occasionally gives her an ache neat the apex. a radiograph reveals a previous root filling (silver cone) which extends 1mm past the apex. around the silver cone is a 3x5mm periaical lesion. The crown of the tooth is partilly broken down and you can see the coronal end of the silver cone . Treatment of choice is

  1. periapical surgery, retrofilling and restoration of the tooth with a synthetic material
  2. extraction of the tooth and replacement with a three unit fixed partial denture
  3. trephination of the lesion and prescription of antibiotics
  4. retreatment , removing the silver point and preparation of the tooth for a post-core restoration
