Local anaesthetics are the most important and most utilized agents in the dental profession today. Achieving effective pain control holds a prime importance for any dental procedure. The most commonly employed technique to achieve effective anaesthesia in mandibular molar teeth with irreversible pulpitis is Inferior Alveolar Nerve Block. However, in some cases this technique may not prove successful and the clinician may have to resort to alternative methods of achieving effective anaesthesia. Our study aims to compare two different techniques employed for anaesthesia, i.e., the conventional Inferior Alveolar Nerve Block and the alternative Gow Gates Technique in achieving effective anaesthesia in mandibular molar teeth.
We conducted a randomized controlled trial in the Operative Dentistry department of Rawal Institute of Health Sciences Islamabad. We selected 102 patients presenting with irreversible pulpitis in mandibular posterior teeth. The selected patients were randomly allocated into two groups. In each group, the subjects were given 1.8 ml of lidocaine (2%) with epinephrine 1: 100,000 (Medicainer Inj, HuonCo., Ltd, Korea) by using anaesthetic cartridges that had aspirating syringe.
Subjects in Group A were given inferior alveolar nerve block while those in Group B received Gow-Gates nerve block. The patients were then asked to rate their pre-operative and intra-operative pain on a visual analogue scale (VAS). Data analysis was done using SPSS-22, followed by comparison of efficacy between the two groups. anaesthesia was found to be effective among 36 subjects (69%) of Group-A and 44 subjects of (84%) Group-B. Hence, we concluded that the success rate of Gow-Gates technique and Inferior alveolar nerve block anaesthetic technique differs significantly.
Gow-Gates technique can be considered as an applicable alternative to the conventional Inferior alveolar nerve block technique while providing anaesthesia to patients presenting with irreversible pulpitis in mandibular posterior teeth, having a higher anaesthetic success of (84%) when compared with the conventional Inferior alveolar nerve block (69%).
局部麻醉剂是当今牙科领域最重要和最常用的药物。实现有效的疼痛控制对任何牙科手术都至关重要。对于患有不可复性牙髓炎的下颌磨牙，最常用的有效麻醉方法是下牙槽神经阻滞麻醉。然而，在某些情况下，这种技术可能并不成功，临床医生可能不得不诉诸其他方法来实现有效的麻醉。我们的研究旨在比较两种不同的麻醉技术，即传统的下牙槽神经阻滞麻醉和替代的 Gow-Gates 技术，以实现下颌磨牙的有效麻醉。
我们在伊斯兰堡 Rawal 健康科学研究所的口腔修复科进行了一项随机对照试验。我们选择了 102 名患有下颌后牙不可复性牙髓炎的患者。将所选患者随机分为两组。在每组中，通过使用带有抽吸注射器的麻醉剂筒，给受试者注射 1.8 毫升含 1:100000 肾上腺素的 2%利多卡因（Medicainer Inj，HuonCo.，Ltd，韩国）。
A 组患者给予下牙槽神经阻滞麻醉，B 组患者给予 Gow-Gates 神经阻滞麻醉。然后让患者在视觉模拟量表（VAS）上对术前和术中疼痛进行评分。使用 SPSS-22 进行数据分析，然后比较两组的疗效。结果发现，A 组 36 例（69%）和 B 组 44 例（84%）患者的麻醉效果有效。因此，我们得出结论，Gow-Gates 技术和下牙槽神经阻滞麻醉技术的成功率有显著差异。
当为患有不可复性牙髓炎的下颌后牙患者提供麻醉时，Gow-Gates 技术可以被认为是传统下牙槽神经阻滞麻醉技术的一种可行替代方法，其麻醉成功率（84%）高于传统下牙槽神经阻滞麻醉（69%）。
