目的牙科治疗过程中经历的疼痛增加了儿童患牙科焦虑症的风险，这些儿童将成为焦虑的成年人，避免牙科护理。因此，提供无痛牙科治疗至关重要。最强烈的恐惧往往与注射有关：因此，能够成功完成无痛恢复治疗而无需局部麻醉注射是一个重要的目标。通过朗加的相对镇痛（RA）技术，一氧化二氮给药已被证明具有镇静和温和的镇痛特性：N2 O发挥其镇痛作用的机制现在已被理解。本研究的目的是测试的镇痛效果的一氧化二氮中使用的RA技术作为唯一的镇痛剂，用于修复治疗的乳磨牙龋齿病变无牙髓involvement.Methods 90例，年龄在3.2和9.4岁之间，38名男性和52名女性，阿萨I和II，包括在研究中。共完成了134例龋损未累及牙髓（1/3 ~ 2/3进入牙本质）的乳磨牙的修复：研究组48例患者在RA下完成了72例修复，对照组42例患者在RA和局部麻醉（LA）下完成了62例修复。在每个疗程结束时，每个患者使用Wong-Baker FACES（R）疼痛评定量表对治疗期间经历的疼痛感觉进行评定。结果在研究组（RA治疗）和对照组（RA加LA治疗）中，自我报告的疼痛感觉无统计学差异。结果还表明，男性和女性之间的疼痛感没有显着差异;年龄以及性别并没有影响groups.Conclusions的结果在朗加的RA技术中使用的一氧化二氮是有效的，在乳磨牙的拔除过程中提供足够的镇痛效果时，没有牙髓参与，不需要LA补充。
Aim Pain experienced during dental treatment increases the risk of developing dental anxiety in children who will became anxious adults, avoiding dental care. It is therefore essential to provide pain-free dental treatment. The strongest fears are often associated with injections: being able to successfully complete painless restorative treatment without the need for local anesthesia injection is therefore an important goal. Nitrous oxide administration by means of Langa's Relative Analgesia (RA) technique has been demonstrated to have both sedative and bland analgesic properties: the mechanism by which N2O exerts its analgesic effects is now understood. The purpose of this study was to test the analgesic effectiveness of Nitrous Oxide used in the RA technique as the only analgesic agent for restorative treatment of primary molars presenting caries lesions without pulp involvement.Methods Ninety patients aged between 3.2 and 9.4 years, 38 males and 52 females, ASA I and II, were included in the study. One hundred and thirty-four restorations were completed on primary molars with caries lesions without pulp involvement (1/3 to 2/3 into dentin): 72 restorations were completed on 48 patients under RA in the Study Group and 62 restorations were performed on 42 patients under RA and local anaesthesia (LA) in the Control Group. At the end of each session, the perception of pain experienced during treatment was rated by each patient using the Wong-Baker FACES (R) Pain Rating Scale.Results No statistical difference on self-reported pain perception was seen in the Study Group (treatment under RA) and in the Control Group (treatment under RA plus LA administration). The results also showed no significant difference in pain sensation between males and females; age as well as gender did not affect the results between groups.Conclusions Nitrous oxide as used in the Langa's RA technique is effective in providing a sufficient analgesic outcome during restorations of primary molars when there is no pulp involvement, with no need for LA supplement.
