This review focused on comparing the anesthetic efficacy of intraosseous injection and conventional inferior alveolar nerve block in mandibular third molar surgery.
Three electronic databases (PubMed, Scopus, and Web of Science) were accessed to identify randomized controlled trials comparing intraosseous injection with conventional inferior alveolar nerve block in mandibular third molar surgery. The outcome measures included onset of anesthesia, success of anesthetic technique, pain during injection of anesthesia, pain during surgery, and duration of anesthesia.
Four studies met the inclusion criteria and consisted of 242 mandibular third molar surgeries. No significant differences were found between the anesthetic techniques in terms of onset of anesthesia, success of anesthetic technique, pain during injection of anesthesia, and pain during surgery. However, the intraosseous technique revealed a significantly shorter duration of anesthesia than the inferior alveolar nerve block (mean difference, -56.34 minutes; 95% confidence interval, -70.72 to -41.97; P < .001).
Despite having anesthetic efficacy similar to that of the conventional inferior alveolar nerve block, intraosseous injection has an added benefit of early recovery of sensation owing to its shorter duration of anesthesia.
本综述旨在比较骨内注射与传统下牙槽神经阻滞在下颌第三磨牙手术中的麻醉效果。
通过 3 个电子数据库（PubMed、Scopus 和 Web of Science）检索比较骨内注射与传统下牙槽神经阻滞在下颌第三磨牙手术中的随机对照试验。结局指标包括麻醉起效时间、麻醉技术成功率、麻醉注射时疼痛、手术时疼痛和麻醉持续时间。
符合纳入标准的 4 项研究共包括 242 例下颌第三磨牙手术。在麻醉起效时间、麻醉技术成功率、麻醉注射时疼痛和手术时疼痛方面，两种麻醉技术之间无显著差异。然而，骨内技术的麻醉持续时间明显短于下牙槽神经阻滞（平均差值，-56.34 分钟；95%置信区间，-70.72 至-41.97；P<.001）。
尽管骨内注射与传统下牙槽神经阻滞的麻醉效果相似，但由于其麻醉持续时间较短，具有感觉早期恢复的额外益处。
