CONSORT Randomized Clinical TrialAnesthetic Efficacy of Supplemental Buccal and Lingual Infiltrations of Articaine and Lidocaine after an Inferior Alveolar Nerve Block in Patients with Irreversible Pulpitis
Section snippets
Methods and Materials
Eighty-seven adult volunteer subjects who reported in the dental emergency department participated in this prospective, randomized, double-blinded study. The sample-size calculation consisted of α level type I error of 0.05 for a two-tailed test and β level type II error of 0.20. A power calculation dictated that a sample size of 63 subjects would give 90% power to detect a 15% difference in the success rate of two test groups. We assumed a dropout rate of approximately 10% to 15% and enrolled
Results
Eighty-four adult volunteer subjects, 44 men and 40 women, with an average age of 29 years, ranging from 23 to 37 years, participated in this prospective, randomized, double-blinded study. Of the original 87 patients, three patients, one from each group, did not have profound lip numbness at 15 minutes and were excluded from the study. The age, sex, initial, and 15 minute post injection pain of all the patients are presented in Table 1. The distribution of teeth for control IANB, IANB +
Discussion
Successful management of painful endodontic emergencies is a challenge for a dentist. Local anesthesia using an inferior alveolar nerve block may provide successful anesthesia in 70% of uninflamed pulp, but the success rate drastically decreases to 30% in patients with irreversible pulpitis 2, 3, 5, 6, 7, 8, 9, 10. It has been quoted that patients with irreversible pulpitis have eight times more chances of failure of local anesthesia as compared with normal patients (14). Literature provides
