Peter's Perforation
A Peter's Perforation" is the result of improper and sometimes careless filing of a tooth's root while performing an endodontic treatment. It is confirmed by a radiographic image (if the provider gets access to the equipment in time). The file or GP can be observed exciting a secondary canal at the apical or middle third of the root. Peter's perforation is often performed by prospective oral surgeons who lack fine touch when doing the quarter turns. Some practitioners attribute this kind of perforation to an attention deficit disorder that specially presents during lecture by some students due to their lack of sleep. It is believe that the term Peter's Perforation was introduce in the summer of 1989 while a young boy from NYC could not stop perforation every toy he played with. It was reinstated 23 years later at HSDM.
