Abstract：
Background Dental extraction is one of the common procedures in the field of dentistry. However, fear and anxiety about local anesthetic injections are unavoidable for most patients. Topical anesthetics, distraction techniques, acupuncture, and the application of heat or cold have been used in practice to alleviate injection-related pain. The specific aim of this study was to compare the pain-relieving efficacy of eutectic mixture of local anesthetics (EMLA) vs. ice during the administration of a long buccal nerve block (LBNB) before dental extraction. Materials and Methods In total, 20 healthy adult patients who required bilateral mandibular posterior teeth extraction under local anesthesia were enrolled. The study was conducted in the Department of Oral and Maxillofacial Surgery, Saveetha Dental College and Hospitals, Chennai, from January 2023 to May 2023. It was a prospective split-mouth study in which each participant was divided into two groups according to the operative site: Group 1, which received a 5% EMLA cream, and Group 2, which received an application of ice before administration of LBNB. There was a one-week interval between the two interventions. The levels of pain and satisfaction were assessed using the visual analogue scale (VAS) and pain perception was evaluated by the sound, eye, motor (SEM) scale. Mann-Whitney U test was applied for the statistical analysis. Results The study included a total of 20 participants, with 14 being male and six being female. The mean age of the study population was 42 ± 15 years. When analyzing the pain scores using the VAS, it was found that Group 1 had a mean score of 2.4 ± 0.44, while Group 2 had a mean score of 3.0 ± 0.44. This difference between the two groups was statistically significant (P = 0.001). It was also found that the mean patient satisfaction score for Group 1 was 9.8 ± 0.22 and for Group 2 was 9.2 ± 0.40 which was statistically significant (p = 0.003). Similarly, Group 1 had a mean SEM score of 1.1 ± 0.1, while Group 2 had a mean SEM score of 1.30 ± 0.46 which was also statistically significant (P =0.016). Conclusion The study results revealed that EMLA has a significant advantage over ice in terms of lower levels of pain, more patient satisfaction, and higher comfort levels. EMLA can be considered the first choice of topical anesthetics, however, ice is recommended in resource-constrained dental set-ups as it is cost-effective.
摘要：
背景技术拔牙是牙科领域中的常见程序之一。然而,对于大多数患者来说，对局部麻醉药注射的恐惧和焦虑是不可避免的。局部麻醉药,分心技术，针灸,和热或冷的应用已在实践中用于减轻注射相关的疼痛。这项研究的具体目的是比较局部麻醉药低共熔混合物（EMLA）与在拔牙前施用长颊神经阻滞（LBNB）期间结冰。材料和方法，选择20例需要在局部麻醉下拔除双侧下颌后牙的健康成人患者。这项研究是在口腔颌面外科进行的，Saveetha牙科学院和医院，钦奈,从2023年1月到2023年5月。这是一项前瞻性的裂口研究，其中每个参与者根据手术部位分为两组：第1组，接受5％EMLA乳膏，和第2组，在施用LBNB之前接受了冰的应用。两次干预之间有一周的间隔。采用视觉模拟量表(VAS)评定疼痛程度和满意度,并通过声音评价疼痛感知,眼睛,电机（SEM）规模。采用Mann-WhitneyU检验进行统计分析。结果本研究共纳入20名参与者,14人是男性，6人是女性。研究人群的平均年龄为42±15岁。当使用VAS分析疼痛评分时，发现第1组的平均得分为2.4±0.44,而第2组的平均得分为3.0±0.44.两组之间的差异具有统计学意义（P=0.001）。还发现，第1组的平均患者满意度评分为9.8±0.22，第2组为9.2±0.40，具有统计学意义（p=0.003）。同样，第1组的平均SEM评分为1.1±0.1，而第2组的平均SEM评分为1.30±0.46，这也具有统计学意义（P=0.016）。结论研究结果表明，EMLA在较低的疼痛程度方面比冰具有显着优势，患者满意度更高，和更高的舒适度。EMLA可以被认为是局部麻醉药的首选，然而,在资源有限的牙科设备中建议使用冰，因为它具有成本效益。
