Pain Perception During Inferior Alveolar Nerve Block Administration in Children Using Vibraject and Dental Vibe Versus Conventional Syringe

Pain Perception During Inferior Alveolar Nerve Block Administration in Children Using Vibraject and Dental Vibe Versus Conventional Syringe: A Randomized Controlled Clinical Trial

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.

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.

The Findings of this study aims to provide evidence-based guidance on the optimal non pharmacological technique to enhance pain-controlled dental procedures allowing better quality of dental treatment and Improve the patient's cooperation and acceptance for future dental visits.

Inclusion Criteria:

• Children aged 6-8 years.
• Cooperative children (Rating 3 or 4 based on the Frankl behaviour scale).
• Medically fit children (ASA I).
• Children mentally capable of communication.
• First dental visit (no previous history of injection of LA).
• Patient requiring extraction/pulp therapy/cavity preparation in mandibular primary molars

Exclusion Criteria:

• Uncooperative patient (other than 3 or 4 based on the Frankl behaviour scale).
• Medically unfit children (other than ASA 1).
• Parental refusal of participation.
• Children under medications (antibiotics and analgesics) for the previous 48 hours that could alter the pain perception.
• Children who are allergic to local anaesthesia.
