Dental anaesthesia for children – effects of a computer-controlled delivery system on pain and heart rate: a randomised clinical trial

British Journal of Oral and Maxillofacial SurgeryAvailable online 22 August 2018AbstractLocal anaesthesia in dentistry is usually given by conventional injection through a syringe. In this randomised, single-blind, split-mouth clinical study we evaluated the perception of pain and changes in heart rate in children being given dental local anaesthesia using a computer-controlled device compared with that given using a traditional syringe. Participants were in good general health with nocontraindications to local anaesthetics. One half of each maxilla was anaesthetised using each technique, the order having been randomly selected according to a computer-generated sequence. The hypothesis was that the controlled anaesthetic flow rate results in virtually imperceptible injections. The outcomes…
