The aim of this randomized clinical trial was to assess the efficacy of exclusive lingual nerve block (LNB) in achieving selective lingual soft-tissue anesthesia in comparison with conventional inferior alveolar nerve block (IANB).
A total of 200 patients indicated for the extraction of lower premolars were recruited for the study. The samples were allocated by randomization into control and study groups. Lingual soft-tissue anesthesia was achieved by IANB and exclusive LNB in the control and study group, respectively. The primary outcome variable studied was anesthesia of ipsilateral lingual mucoperiosteum, floor of mouth and tongue. The secondary variables assessed were (1) taste sensation immediately following administration of local anesthesia and (2) mouth opening and lingual nerve paresthesia on the first postoperative day.
Data analysis for descriptive and inferential statistics was performed using SPSS (IBM SPSS Statistics for Windows, Version 22.0, Armonk, NY: IBM Corp. Released 2013) and a < 0.05 was considered statistically significant. In comparison with the control group, the study group (LNB) showed statistically significant anesthesia of the lingual gingiva of incisors, molars, anterior floor of the mouth, and anterior tongue.
Exclusive LNB is superior to IAN nerve block in achieving selective anesthesia of lingual soft tissues. It is technically simple and associated with minimal complications as compared to IAN block.
本随机临床试验的目的是评估与传统下牙槽神经阻滞(IANB)相比,单纯舌神经阻滞(LNB)在实现选择性舌软组织麻醉方面的疗效。
共招募了200名拟拔除下颌前磨牙的患者进行研究。样本通过随机分组分为对照组和研究组。对照组通过IANB实现舌软组织麻醉,研究组通过单纯LNB实现。研究的主要结局变量是同侧舌黏膜骨膜、口底和舌的麻醉情况。评估的次要变量为:(1)局部麻醉给药后立即的味觉;(2)术后第一天的张口度和舌神经感觉异常。
使用SPSS(IBM SPSS Statistics for Windows,版本22.0,纽约州阿蒙克:IBM公司。2013年发布)进行描述性和推断性统计分析,P<0.05被认为具有统计学意义。与对照组相比,研究组(LNB)在切牙、磨牙舌侧牙龈、口底前部和舌前部的麻醉方面具有统计学意义。
单纯LNB在实现舌软组织选择性麻醉方面优于IAN神经阻滞。与IAN阻滞相比,其技术操作简单,并发症最少。
