Study Overview
Brief Summary
This RCT study aims to establish evidence based decision comparing between Vibraject (MiltexInc LLC.,York,PA,USA).and Dental vibe(BING Innovations LLC,Crystal Lake,IL,USA versus Conventional Syringe on pain perception during inferior alveolar nerve block anesthesia in lower primary molars indicated for extraction,pulp therapy and cavity preparation in Children.
Detailed Description
This randomized controlled clinical trial aims to compare pain perception of Vibraject and dental vibe during inferior alveolar nerve block in lower primary molars indiacted for extraction,pulp therapy and cavity preparation in children aged 6-8 years.
Pain during local anesthesia remains a major concern in pediatric dentistry, as it contributes significantly to fear, anxiety, and uncooperative behavior in children. Vibration devices, based on the gate control theory of pain, have been introduced as a non-pharmacological method to reduce injection discomfort.
Ninety children will be randomly allocated into 3 parallel groups(1:1:1): Inferior alveolar nerve block Injection using Vibraject system,Inferior alveolar nerve block Injection using Dentalvibe system, Inferior alveolar nerve block Injection using the Conventional Syringe.
All participants will undergo standardized procedures, including topical anesthesia application followed by local anesthetic injection using articaine. Pain perception during injection will be assessed using both subjective and objective measures.
The primary outcome is subjective pain perception during injection measured using Wong-Baker Scale,While secondary outcome is objective pain perception during injection measured using FLACC Scale,Finally The Physiological parameters(heart rate, oxygen saturation )will be measured at two time points: baseline and during injection using pulse oximeter device on child's index finger.

Arms & Interventions
Inferior alveolar nerve block Injection using Vibraject system(MiltexInc LLC.,York,PA,USA).
VibraJect is a compact, battery-operated unit that attaches directly to a standard dental syringe, generating high-frequency vibrations along the needle to attenuate pain during anesthetic delivery. If these devices prove efficacy, they may offer a rapid, non-pharmacologic method to enhance the comfort of children undergoing local anesthesia.
Intervention: Vibraject (Device)
Inferior alveolar nerve block Injection using Dentalvibe system (BING Innovations LLC,Crystal La).
The DentalVibe device is a cordless, rechargeable instrument that produces controlled, pulsed micro-vibrations at the injection site. It features a U-shaped vibrating tip connected to a microprocessor-driven VibraPulse motor, allowing gentle stimulation of sensory receptors, illumination of the injection area, and retraction of the cheek or lip.
Intervention: Dental vibe (Device)
Inferior alveolar nerve block Injection using the Conventional Syringe.
A conventional metal aspirating syringe
Intervention: Conventional syringe (Device)
Outcomes
Primary Outcomes
Subjective pain during injection
Time Frame: during injection
Wong-Baker Scale: represents a series of faces from a 0-value happy face (which represents lack of pain) to a 10-value crying face (which suggests the worst possible pain). On this basis, the patient chooses the face that best describes his/her level of pain.
Secondary Outcomes
- Objective pain during injection(Baseline and during injection)
