In this incident there was a report a injury to the pt, a tooth needed to be extracted after a file broke in the tooth.
The file malfunctioned.
Options available for the management of a broken instrument include observation only, attempts at nonsurgical removal, periradicular surgery, intentional replantation, root resection and extraction.
The latter four involve surgical intervention and are only done if signs and symptoms warrant.
Expert opinion on file indicates that surgical treatment is often unnecessary and inadvisable and should not be performed "automatically" because of the file breakage but only if other alternative treatments are not viable or successful and signs and symptoms warrant.
Since the doctor opted to do an extraction the same day, user misjudgement and inappropriate use of surgical intervention cannot be ruled out.
In other instances, a broken file has caused or contributed to surgical intervention and therefore, this incident should be reported.
