The aim of the present study was to describe the frequency of dental injuries over a 10-year period, where a mouthguard was used in approximately 10% of intubation cases or endoscopying. The types of injury are presented and the use of different types of mouthguard is discussed. Among 120,086 procedures involving anaesthesia carried out in the period 1983-1992 at Bispebjerg Hospital, Copenhagen, 75 cases of dental trauma occurred. The incidence of dental traumatic injuries was 0.06%. Although eight patients had used mouthguards they were registered with traumatic injuries to the teeth in connection with general anaesthesia. Of the patients, 58% were women and 42% men, with a mean age of 61 years. Seventy-eight percent of the injuries were located in the maxilla and 91% of these involved the incisor area of the maxilla. Forty-one percent were classified as lateral luxations or mobile teeth, 47% were classified as fractured teeth, 10% tooth avulsions and the remaining 2% were classified as concussions. Because of the low frequency of traumatic dental injuries in connection with general anaesthesia and the non-significant effect of the use of mouthguards, routine use of mouthguards is not recommended. Only when a patient is to have an endoscopy done under general anaesthesia, and the surgeon or anaesthesiologist foresees problems (restricted mouth opening, extensive fixed prosthetics, extensive loss of marginal bone) is use of an individually made mouthguard indicated.
本研究的目的是描述10年间牙科损伤的发生率，在此期间约10%的插管病例或内镜检查中使用了口腔防护器。文中介绍了损伤类型并讨论了不同类型口腔防护器的使用情况。在1983年至1992年期间于哥本哈根比斯佩比约格医院进行的120,086例麻醉手术中，发生了75例牙科创伤。牙科创伤性损伤的发生率为0.06%。尽管有8名患者使用了口腔防护器，但他们仍被记录为在全身麻醉期间发生了牙齿创伤。患者中，58%为女性，42%为男性，平均年龄为61岁。78%的损伤位于上颌骨，其中91%涉及上颌骨的切牙区。41%被归类为侧方脱位或牙齿松动，47%被归类为牙齿折断，10%为牙齿脱落，其余2%为脑震荡。由于全身麻醉相关的牙科创伤发生率较低，且使用口腔防护器的效果不显著，因此不建议常规使用口腔防护器。仅当患者在全身麻醉下进行内镜检查，且外科医生或麻醉医生预见有问题（张口受限、广泛的固定修复体、大量边缘骨丧失）时，才建议使用定制的口腔防护器。
