Abstract
Aim and objective of the Study • To measure the efficacy of articaine and mepivacine buccal infiltrations supplemental to mepivacine IANB on mandibular first molar pulp anaesthesia. • To determine the time of onset and duration of pulpal anaesthesia for each treatment. • To assess patient reported feelings of numbness in teeth and soft tissues after each local anaesthetic injection Materials & Methods • The volunteers received LA regimens randomly over two visits, at least one week apart following reading the information sheet and signing the formal consent • The efficacy of pulp anaesthesia was determined by electronic pulp testing • The efficacy of pulp anaesthesia was evaluated for mandibular first molar after both treatments before injection (baseline) and at intervals of 2 minutes for the first ten minutes and then at intervals of five minutes until 45 minutes after the injection. A control unanaesthetised tooth on the other side of the lower jaw was tested at base line, once again at 10 minutes and at the end of the trial (45 minutes). • The discomfort of the injections was recorded by the volunteers after each treatment on standard 100mm visual analogue scales (VAS), with “no pain†(0 mm) and “unbearable pain†(100 mm). • After all injections, the volunteers were asked to subjectively gauge soft tissue anaesthesia of the lower lip, tongue, and teeth as soon as numbness is felt following either treatment. Results • All (23 volunteers) secured anesthetic success for first molar tooth following pulp testing after articaine and mepivacaine regimens within 10 min and continuously sustained for 45 min postinjection (P = 1). • Differences between articaine regimen and mepivacaine regimen are statistically significant in regard to the number of episodes when there are no sensation on first molar pulp testing on 64 reading (maximum stimulation) at 2 min (P = 0.008) and 4 min (P = 0.019) but not at 6 min (P = 0.15) or 8 min (P = 0.32).
