Dentistry utilizes many resources with the intention of reducing patient anxiety during local anesthetic administration. Objective The purpose of this study was to compare the use of a new needle-less intraligamentary injection device, the Numbee by BioDent Simi Valley, CA to the traditional Inferior Alveolar Nerve IAN block. This study evaluated pain upon injection and potential to achieve pulpal anesthesia during a caries restorative procedure on mandibular teeth. Methods A randomized, split-mouth design of 15 adult subjects receiving two anesthetic dental injections using 2 lidocaine with 1100,000 epinephrine was conducted. Subjects received an IAN block on one side of the mandibular arch and a Numbee injection on the same tooth type molar, premolar on the contralateral side. Subjects recorded injection pain using the Visual Analog Scale VAS and the injection technique they generally preferred. An electric pulp tester EPT was used to assess pulpal anesthesia at 5-, 15-, 30-, 45- and 60-minute intervals. Anesthesia was considered profound with two consecutive EPT readings of 80 EPT maximum output. If subjects became symptomatic during the restorative procedure, rescue anesthesia was administered.
