Nitrous oxide may be used to alleviate dental anxiety and to diminish or eliminate dental pain. The benefit of nitrous oxide sedation is a cooperative and satisfied patient. By reducing the patient's perception of pain it allows them to relax and cooperate during dental procedures. However, the dental surgery personnel, chronically exposed to N2O, are at serious risk. The chronic effects of occupational exposure to nitrous oxide have long been the subject of debate. Safety standards have been established in the United States and Europe since many years. The potential detrimental action on the reproductive, neurological, haematological, hepatic and renal systems, plus the possibility of increased cancer risk have been the subject of active research, although absolute occupational effects are still uncertain. To provide a safer work-place for those at risk of exposure to waste anesthetic gases, preventive measures are recommended.
一氧化二氮可用于缓解牙科焦虑，并减轻或消除牙痛。一氧化二氮镇静的好处是让患者配合并感到满意。通过降低患者对疼痛的感知，它使患者在牙科手术过程中能够放松并配合。然而，长期接触一氧化二氮的牙科手术人员面临严重风险。职业性接触一氧化二氮的长期影响长期以来一直是争论的话题。美国和欧洲多年来已制定了安全标准。尽管绝对的职业影响仍不确定，但对生殖、神经、血液、肝脏和肾脏系统的潜在有害作用，以及癌症风险增加的可能性一直是积极研究的课题。为为那些有接触废弃麻醉气体风险的人提供一个更安全的工作场所，建议采取预防措施。
