Children's fear of the injection of local anesthetic agents affects their cooperation in pediatric dentistry. Different techniques are available to decrease the injection pain, including the use of precooling agents or vibrators. The present study investigated the effectiveness of Buzzy (Buzzy MMJ Labs, Atlanta, GA, USA). This device transfers cold and external vibration to the injection site during the inferior alveolar nerve block (IANB) injection. The present self-control, randomized, and double-blind clinical trial evaluated 30 children aged 6-12, who had bilateral mandibular permanent or primary carious molar teeth. On one side, the BUZZY was applied before and during the IANB injection, and the other side was considered as control. On both sides, a topical anesthetic gel was applied before injection. The pain severity and children's anxiety were determined using Wong-Baker, face, leg, activity, cry, consolability (FLACC) scales, and the heart rate. The mean age of the participants was 7.18 ± 1.5 years, with 12 girls and 18 boys. The Wong-Baker scale and FLACC scale did not show any statistically significant difference between BUZZY and control ( value = 0.9 and 0.15, respectively). In addition, BUZZY tool did not significantly decrease pain and anxiety during injection, assessed through the heart rate difference (=0.38). Under the limitations of the present study, a combination of precooling and vibration using the BUZZY device did not decrease pain and anxiety in children during the IANB injection.
儿童对局部麻醉剂注射的恐惧会影响他们在儿童牙科治疗中的配合度。有多种技术可用于减轻注射疼痛，包括使用预冷剂或振动器。本研究调查了Buzzy（美国佐治亚州亚特兰大市Buzzy MMJ实验室）的有效性。该设备在下牙槽神经阻滞（IANB）注射过程中将冷感和外部振动传递至注射部位。本项自我对照、随机、双盲临床试验评估了30名6至12岁的儿童，这些儿童双侧下颌有恒牙或乳牙龋齿磨牙。一侧在IANB注射前和注射过程中使用Buzzy，另一侧作为对照。两侧在注射前均涂抹局部麻醉凝胶。使用面部表情、腿部动作、活动、哭闹、安慰程度（FLACC）量表以及心率来确定疼痛严重程度和儿童的焦虑程度。参与者的平均年龄为7.18±1.5岁，其中有12名女孩和18名男孩。Wong-Baker量表和FLACC量表显示，Buzzy组与对照组之间在统计学上无显著差异（分别为P值=0.9和0.15）。此外，通过心率差异评估（P=0.38），Buzzy工具在注射过程中并未显著减轻疼痛和焦虑。在本研究的局限性条件下，使用Buzzy设备进行预冷和振动相结合的方法，在IANB注射过程中并未减轻儿童的疼痛和焦虑。
