Injury to elongated, upper convex, isolated, mobile, and prosthetic (crown & bridge) teeth may occur during oro-tracheal intubation under general anesthesia.<br>Three types of protectors were studied in 32 of the 192 patients given general anesthesia from June to October 1993 at our hospital.<br>The first type, "Modeling Compound", proved to be useful, but some problems were noted. The second type, "premade protector", was not always suitable for elongated, upper convex, or isolated teeth or individual irregularities.<br>The third type, "Pressed custom-made protector", can be adapted for all patients, but it is costly and time consuming prior to the operation.<br>In conclusion, in addition to "Modeling Compound" which is currently being used at our hospital, we are adopting the "Pressed custom-made" type as an additional protector.
