Effect of Pre-Warming of Local Anesthesia in Reducing Pain Perception During Injection in Children: A Randomized Controlled Clinical Trial

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 72 (actual)
• Sponsor: Andrew Emad · Academic / Other
• Sex: All
• Age: 5 Years – 7 Years
• Healthy volunteers: Not accepted

Summary

The aim of the current study was to evaluate the pain perception upon injection of pre-warmed dental anesthetic solution (at 370C and 400C) versus that at room temperature (Average 23 degrees) during Maxillary Infiltration and Mandibular Inferior Alveolar Nerve Block techniques in children

Conditions

• Local Anesthesia
• Dental Anesthesia

Interventions

Type	Name	Description
OTHER	Local anesthesia solution at room temperature	The local anesthesia cartridge is used at room temperature (average of 21 °C)
OTHER	Local anesthesia solution pre-warmed to 37°C	About 150 ml of water at 21°C is added to the heating compartment of the heating device. The Local anesthesia cartridge is placed at the bottom of the heating compartment. The device is plugged in and the control gauge is set at the "Express milk warming setting for contents up to 180ml/6oz" mark. The contents would reach 37°C at 120 seconds.
OTHER	Local anesthesia solution pre-warmed to 40°C	About 150 ml of water at 21°C is added to the heating compartment of the heating device. The Local anesthesia cartridge is placed at the bottom of the heating compartment. The device is plugged in and the control gauge is set at the "Express milk warming setting for contents up to 180ml/6oz" mark. The contents would reach 40°C at 130 seconds.
OTHER	Maxillary infiltration technique	A 30 gauge short needle is oriented so that the bevel is facing the bone. The syringe is held parallel to the long axis of the tooth and the needle is inserted into the height of the mucobuccal fold over the offending tooth. The needle is advanced to a depth of 1 millimeter into the tissues. Aspiration is done, and once it is negative then 0.6 ml (nearly one third of the cartridge) of the anesthetic solution is injected slowly without permitting the tissues to balloon.
OTHER	Inferior alveolar nerve block technique	While the mouth is opened as wide as possible, the index finger palpates the external oblique ridge reaching the Coronoid notch. A 27-gauge long dental needle will be used for injection. The needle will be directed between the two primary molars on the opposing side of the arch, penetrating the tissues at the point halfway between coronoid notch and the pterygomandibular raphe at the occlusal plane level or slightly lower.The needle is withdrawn 2mm to aspirate. Once negative aspiration is checked, the remainder of the solution is deposited slowly. Approximately 1.0 mL of LA will be delivered near the inferior alveolar nerve. The average depth of insertion is about 15mm, which is nearly two-thirds the needle length.
