Inferior Alveolar Nerve Block Injection Pain Using a Computer-Controlled Local Anesthetic Device (CCLAD): A Prospective, Randomized Study.

Inferior Alveolar Nerve Block Injection Pain Using a Computer-Controlled Local Anesthetic Device (CCLAD): A Prospective, Randomized Study. Anesth Prog. 2018;65(4):231-236 Authors: Fowler S, Crowley C, Drum M, Reader A, Nusstein J, Beck M Abstract There is evidence that the Computer-Controlled Local Anesthetic Device (CCLAD) decreases the pain of oral injections. The purpose of this study was to evaluate injection pain of the inferior alveolar nerve block (IANB) using the CCLAD in an upright position versus a supine position. Additionally, we evaluated solution deposition pain with the CCLAD when compared to previous studies using a traditional syringe. One hundred ten asymptomatic subjects were randomly given IANBs using 2% lidocaine with 1:100,000 epinephrine while in an upright sitting position and supine position, at 2 different appointments, spaced at least 2 weeks apart. Each subject rated the pain for needle insertion, needle placement, and solution deposition on a Heft-Parker visual analogue scale. Pain ratings were compared between the upright and supine positions using a repeated-measures analysis of variance with post hoc testing using the Tukey-Kramer procedure. Moderate to severe pain was reported by 10% to 13% of the patients for needle insertion, 74% to 75% for full needle placement, and 8% to 10% for solution deposition. There was no significant difference between groups for phases of the injection. When comparing the ...
