Abstract:

Medical emergencies that are life-threatening can occur in dental practice. Anxiety，tension，pain and discomfort during dental treatment are thought to be causative factors.Other causes may be related to allergic and toxic reactions to local anesthetics. Complications may arise because of an underlying disease-specific pathology such as epilepsy，cardiovascular diseases and hyperthyroidism etc. Consequently，it is important to decide whether the dental treatment concerned could be safely performed in order to prevent medical emergencies.

Key words: dental treatment, medical emergencies, prevention

摘要：

口腔诊疗的各个环节中都存在突发意外医疗事件的可能。患者的焦虑、恐惧、口腔治疗中的不适和疼痛，手术中所使用的局部麻醉药，以及患者全身系统性疾病如癫痫、心血管疾病和甲状腺功能亢进症等，均可影响口腔治疗，增加治疗风险。因此，是否采取适当的口腔治疗对防范突发医疗事件的发生十分重要。
