Methods Thirty-one healthy adult volunteers received the following local anaesthetic regimens adjacent to a mandibular central incisor: 1 buccal infiltration of 1. Pulp sensitivities of the central incisor and contralateral lateral incisor were assessed electronically. Anaesthetic efficacy was determined by two methods: 1 Recording the number of episodes with no responses to maximal electronic pulp tester stimulation during the course of the study period, 2 recording the number of volunteers with no response to maximal pulp tester stimulation within 15 min and maintained for 45 min defined as sustained anaesthesia.
Data were analysed by McNemar, chi-square, Mann-Whitney and paired t—tests. Results For both test teeth, the number of episodes of no sensation on maximal stimulation was significantly greater after articaine than lidocaine for both techniques.
Effective pulpal anaesthesia is essential for many dental procedures, and predictable local anaesthetic regimens are important in reducing the fear and anxiety that dentistry might provoke. Despite a range of commercially available local anaesthetic drugs, lidocaine remains the most commonly employed in dentistry in the United Kingdom, with an excellent safety record. Regional blocks do not always result in successful pulpal anaesthesia for lower anterior teeth.
Their study included only lidocaine with adrenaline. Nuzum et al. The primary outcome measure was pulp anaesthesia negative response to electronic pulp testing. The secondary outcomes were onset time and injection discomfort.
