title: Use of anorganic bone in periapical defects following apical surgery--a prospective trial.
abstract: Anorganic bovine bone has been used previously to obturate bony defects following apical surgery with some reported success. However, no prospective trial has been carried out. We present the results of our trial showing that the placement of anorganic bovine bone (BIO-OSS) in defects created by apical surgery is contraindicated.
