Dental damage is the most common reason for complaints against anaesthetists. The purpose of this study was to investigate the common belief that the use of a toothguard at the time of intubation causes intubation to be more difficult. We studied 80 patients, half of whom were intubated with a toothguard in situ and the other half intubated without a toothguard. The time taken from mouth opening to successful passage of the tracheal tube through the vocal cords was measured. In the toothguard group, the recorded time also included the time taken to insert the toothguard. The median time to intubation in the group with a toothguard was 24 s and the median time to intubation in the group without a toothguard was 17 s. The difference of 7 s in the time to intubation was statistically significant (p =0.0003). As the recorded times also included the time taken to insert the toothguard, we do not regard this result to be clinically significant and believe that anaesthetists should think carefully before disregarding this simple protective device.
