The Effects of Virtual Reality and External Cooling and Vibration on Dental Anxiety and Pain During Inferior Alveolar Nerve Block in Children: a Randomized Clinical Trial
The Effects of Virtual Reality and External Cooling and Vibration on Dental Anxiety and Pain During Inferior Alveolar Nerve Block in Children: a Randomized Clinical Trial
Objectives: To compare the effectiveness of virtual reality (VR) and external cooling and vibration distraction techniques on dental anxiety and pain in children during inferior alveolar nerve block (IANB).
Materials and Methods: This randomized controlled parallel arm trial included 120 children aged between 6-12 years old who required IANB. Children were randomly divided following three groups: Group I: VR eyeglasses, Group II: Buzzy® device, and Group 3: Control (conventional behavior management technique). Dental anxiety levels were measured by the pulse rate and oxygen saturation level before, during, and after IANB procedure. Pain perception during IANB procedure was assessed using the Face, Legs, Activity, Cry, Consolability (FLACC) Scale, Wong Baker Faces Scale (WBS), and Visual Analog Scale (VAS).
This study was designed as a three-arm parallel randomized controlled trial to compare the effects of virtual reality (VR) and external cooling and vibration on dental anxiety and pain during inferior alveolar nerve block (IANB) in children aged 6 to 12 years old.
The sample size consisted of 120 children, and the patients were randomly divided following three different groups: Group I: VR eyeglasses group, Group II: Buzzy® device group, and Group III: Control group.
Group I (VR eylasses): In the present study, 3D VR eyeglasses (Oculus Quest 2, Oculus Go, Facebook Technologies, Auburn, USA) were used for VR distraction.
Group II (Buzzy® device): In the present study, the Buzzy® device (MMJ Labs, Atlanta, GA, USA), consisting of a bee-shaped vibrating body and removable wing-shaped cold gel packs, was used for external cooling and vibration application.
Group III (Control): In the present study, group III received conventional behavior management technique (tell-show-do) during the administration of IANB.
Administration of IANB: The oral mucosa was dried with air-water spray and topical anesthetic solution (Vemcaine %10 Lidocaine, VEM Co. Ltd., Istanbul, Turkey) was applied to the dry mucosa with a cotton pellet for 1 minute. The patient was asked to open his/her mouth as wide as possible, and then IANB was administred using 2 ml of 4% articaine with 1:100.000 adrenaline (Ultracaine DS® Forte, Sanofi Health Products Co. Ltd., Istanbul, Turkey) using an automatic aspirated Aspiject® carpule syringe (RØNVIG Dental Mfg. A/S, Daugaard, Denmark) with a 35 mm 27 gauge needle at a rate of 1 ml/minute. In order to ensure standardisation, each patient received the same dosage of local anesthetic and the IANB procedure was provided by the same investigator.
Dental anxiety and pain assessment In order to evaluate physiological changes associated with anxiety, oxygen saturation (SpO2) and pulse rate (PR) values were recorded using pediatric fingertip pulse oximeter (ChoiceMMed, Beijing Choice Electronic Technology Co., Ltd, China) 1 minutes before, during, and 1 minutes after the administration of IANB.
For objective assessment of pain during the IANB procedure, the Face, Legs, Activity, Cry, Consolability (FLACC) Behavioral Pain Assessment Scale was used. The FLACC scores were assessed by another investigator not involved in the IANB procedure.
The Wong Baker Face (WBS) and the Visual Analog Scale (VAS), two commonly used and valid pain measurment scale for pediatric patients, were used to assess the self perception of pain. Both scales were explained to the patients, and they were asked to choose the facial expression (for WBS) and the number (for VAS) that best reflected their current level of pain during the IANB procedure.
