BACKGROUND. Pain following the extraction of the primary canine in children with palatally displaced canines (PDC) as an interceptive treatment has not been investigated. AIMS. To describe pain, discomfort, dental anxiety, and use of analgesics following the extraction of primary canines in children with PDC. DESIGN. Forty-four children, aged 10-13 with PDC, were included. Pain intensity, discomfort, and analgesic consumption were rated the first evening and 1 week after the extraction of the primary canine. Dental anxiety was assessed pre-extraction, using the dental anxiety scale (DAS). A matched reference group also completed the DAS. RESULTS. No significant differences were found between the study and the reference group regarding the pre-extraction assessments. Post-extraction pain and discomfort was low. The experience of the injection was graded worse than the extraction, and more pain was rated at the evening post-extraction than during the extraction. Analgesics were used only the first evening. High correlation was detected between DAS and pain during injection and extraction. CONCLUSIONS. The experience of pain and discomfort during and after extraction of the primary canines is low, despite that 42% of the children used analgesics. Therefore, appropriate analgesics and recommendation doses pre- and post-extraction should be prescribed.
作为一种阻断性治疗，在存在腭侧错位尖牙的儿童中拔除乳尖牙后是否会出现疼痛尚未得到调查。
描述腭侧错位尖牙儿童拔除乳尖牙后第一晚和一周后的疼痛、不适、牙科焦虑和镇痛药使用情况。
纳入 44 名年龄在 10-13 岁的存在腭侧错位尖牙的儿童。在拔除乳尖牙后的第一晚和一周后，评估疼痛强度、不适和镇痛药的使用情况。在拔牙前，使用牙科焦虑量表（DAS）评估牙科焦虑。一个匹配的对照组也完成了 DAS 评估。
在拔牙前的评估中，研究组和对照组之间没有发现显著差异。拔牙后的疼痛和不适程度较低。注射的体验比拔牙差，且拔牙后第一晚的疼痛评分高于拔牙时。仅在第一晚使用了镇痛药。DAS 与注射和拔牙时的疼痛之间存在高度相关性。
尽管 42%的儿童使用了镇痛药，但拔除乳尖牙过程中和之后的疼痛和不适体验较低。因此，拔牙前后应适当开具镇痛药并推荐剂量。
