# Which of the following is classified as a procedural accident?
a. Extensive caries preventing adequate rubber dam isolation
b. Inability to obtain reliable pulp testing results
c. A separated instrument
d. Swelling after nonsurgical root canal treatment
The correct answer is C. A separated instrument.
Procedural accidents are one reason for referral and are a direct result of treatment rather than preoperative conditions, diagnostic testing, or postoperative symptoms. A separated instrument is one of the most difficult accidents to correct.
