Conventional Versus Computer-Assisted Dental Anesthesia
Sponsor: University of Montemorelos
Summary
The purpose of this clinical trial was to compare two methods of delivering local dental anesthesia in undergraduate dental students: a computer-controlled local anesthetic delivery (CCLAD) system and a conventional dental syringe. The study evaluated whether the computer-controlled system reduced pain during the administration of local anesthesia compared with the conventional technique. The main questions this study aimed to answer were: Does a computer-controlled local anesthetic delivery system reduce pain during maxillary buccal infiltration compared with a conventional dental syringe? Are there differences in physiological responses (blood pressure, heart rate, and oxygen saturation) between the two anesthetic delivery methods? Which anesthetic delivery method do participants prefer after experiencing both techniques? Would participants recommend their preferred anesthetic delivery method to others? Participants attended two study visits approximately one week apart. Each participant received local anesthesia using both delivery methods in a randomized order, serving as his or her own control. Pain, dental anxiety, physiological parameters, anesthetic delivery preferences, and willingness to recommend the preferred method were assessed during the study.

Interventions
Computer-Controlled Local Anesthetic Delivery System
Local anesthetic was administered using a computer-controlled local anesthetic delivery (CCLAD) system with 2% lidocaine containing 1:100,000 epinephrine through a 27-gauge short dental needle for maxillary buccal infiltration anesthesia. The device controlled the flow rate throughout anesthetic administration according to the manufacturer's operating protocol.
Conventional Aspirating Dental Syringe
Local anesthetic was administered using a conventional aspirating dental syringe with 2% lidocaine containing 1:100,000 epinephrine through a 27-gauge short dental needle for maxillary buccal infiltration anesthesia. Anesthetic administration followed the conventional manual injection technique.
