Pain control is a crucial aspect of pediatric dentistry for patient management. Thermo-mechanical devices (Buzzy™ Pain Care Labs, USA) work on the concept of vibration and cooling and have shown promising results in pain control during local anesthesia in pediatric dentistry. On the other hand, audio distraction has also been used for pain management. The amount of pain endured is determined by the patient's perception and attentiveness. Thus, if audio function is added to the thermomechanical device it might increase its efficiency. Hence, the present study aimed to compare pain on injection using a thermo-mechanical device with and without audio during inferior alveolar nerve block (IANB) injection in children aged 5-10 years old.
Twenty-eight children aged between 5 and 10 indicated for IANB were included in this randomized study. Children who were undergoing the dental procedure were divided into 2 groups, with 14 children in each group. The study group was the thermo-mechanical device with audio distraction; the control group was the thermo-mechanical device without audio distraction. IANB was administered. Subjective pain evaluation was performed using the Wong-Baker Faces Pain Rating Scale (WBFPR) and objective pain evaluation was done using the Faces, Leg, Activity, Consolability, Cry (FLACC) scale.
The outcome depicted a significant reduction in pain on injection for both objective and subjective evaluations in the thermo-mechanical device with an audio distraction group.
Less pain on injection was observed, when a thermo-mechanical device was used with audio distraction for IANB procedures.
疼痛控制是儿童牙科患者管理的关键环节。热机械装置（美国Buzzy™疼痛护理实验室）基于振动和冷却原理工作，在儿童牙科局部麻醉期间的疼痛控制方面已显示出有前景的结果。另一方面，音频分心也已用于疼痛管理。患者忍受的疼痛程度由其感知和注意力决定。因此，如果在热机械装置中增加音频功能，可能会提高其效率。因此，本研究旨在比较5至10岁儿童在下牙槽神经阻滞（IANB）注射过程中使用带音频和不带音频的热机械装置时的注射疼痛情况。
本随机研究纳入了28名年龄在5至10岁、需要进行IANB的儿童。接受牙科治疗的儿童被分为2组，每组14名儿童。研究组为带音频分心的热机械装置组；对照组为不带音频分心的热机械装置组。进行IANB注射。使用面部表情疼痛评分量表（WBFPR）进行主观疼痛评估，使用面部、腿部、活动、安抚、哭泣（FLACC）量表进行客观疼痛评估。
结果表明，在带音频分心的热机械装置组中，客观和主观评估的注射疼痛均显著减轻。
在下牙槽神经阻滞操作中，当热机械装置与音频分心一起使用时，观察到注射时的疼痛减轻。
