Pain Assessment During Mandibular Nerve Block Injection With the Aid of Dental Vibe Tool in Pediatric Dental Patients

Pain Assessment During Mandibular Nerve Block Injection With the Aid of Dental Vibe Tool in Pediatric Dental Patients: A Randomized Controlled Trial.

The purpose of this study is to valuate the effectiveness of DentalVibe(DV) tool in pain reduction during local anesthetic injection compared to traditional injection without aid of DentalVibe in pediatric patients.

This study is a crossover randomized controlled clinical trial where (N=60 ) children will be selected from the outpatient clinic of Pediatric Dentistry and Public Health Department, Faculty of Dentistry, Alexandria University after securing necessary consents. These children will be selected based on a need for local anesthesia for pulpotomy treatment on both sides of the mandible. All selected children will be randomly allocated into 2 groups. Group I (assigned to injection with the aid of DentalVibe tool), Group II(assigned to conventional injection). Each group will receive 2 mandibular nerve block injections with two different injection techniques, with 1-2 weeks apart as a washing out period. Mandibular nerve block injection will be either with vibration using DentalVibe at the injection side or topical analgesic (benzocaine 20%) gel will be applied before the injection of local anesthesia at first the appointment, and the alternative technique will be used at the second appointment . Injection with the aid of DentalVibe tool will act as the experimental group while the control group will be the use of topical analgesic (benzocaine 20%).

Inclusion Criteria:

• Age range from 5-7 years.
• Patients who are in need of pulpotomy dental treatment requiring bilateral local anesthesia in the mandible.
• Children free of any systemic disease or special health care needs.
• Positive or definitely positive behavior during preoperative assessments according to the Frankl Scale.

Exclusion Criteria:

• Having active sites of pathosis in the area of injection that could affect anesthetic assessment.
• Signs of irreversible pulpitis or pulp necrosis.
• Radiographs show periapical or bifurcation radiolucency.
• Patients allergic to local anesthesia or having a family history of allergy to local anesthesia.
• Patients with acute oral or facial infection (swelling and/or cellulitis).
• Patients refusing to participate.
