Dental damage during anaesthesia and surgery.

A review of the Accident Compensation Corporation (ACC) files on dental damage following anaesthesia or surgery was undertaken along with a survey of New Zealand anaesthetists asking about their practice with respect to protection of teeth during anaesthesia. These results confirm that damage is relatively common and that the majority of damaged teeth (62%) were known to have been previously restored, or weakened through periodontal disease prior to the damage occurring. The anaesthetists surveyed thought that dental damage was even more common than shown from the ACC records, and yet the vast majority of them did not routinely use specific protective guards and 45% of them did not ever use protective guards of any type.
