Anesthetic Efficacy of 4% Articaine Versus 2% Lidocaine in Lower Central Incisors - A Comparative Study
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 4
Abstract
Introduction: Adequate pain control is the cornerstone of any successful dental treatment. Study was done to assess the efficacy of 4% articaine and 2% lidocaine in achieving anesthesia in Lower central incisors. Material and methods: This study included 24 patients with otherwise normal mandibular central incisors. Each Patient was administered local anaesthesia during two separate appointments where 1.8 ml of 2% lidocaine with 1:100000 epinephrine was administered in the first visit and 1.8 ml 4% articaine with 1:100,000 epinephrine in the second visit in the labial sulcus adjacent to the mandibular right central incisor. The response of the test tooth was assessed using Endo Ice® and Electric Pulp Tester (EPT) for every 5 minutes for up to a maximum of 1 hour after injection or till the tooth became responsive whichever was earlier. Results: The mean onset of pulpal anesthesia for 2% Lidocaine 8.4 (S.D., 2.5 min), and 4% Articaine is 7.4 (S.D., 3.0 min), respectively. The mean duration of pulpal anesthesia on EPT for 2% Lidocaine and 4% Articaine was 10.41 (S.D, 8.58 min) and 20.6 (S.D, 12 min) respectively and the mean duration of pulpal anesthesia on Endo-Ice 2% Lidocaine and 4% Articaine was 13.75 (S.D., 8.37 min) and 29.16 (S.D., 8.03 min) respectively. Conclusion: Articaine demonstrated a higher percentage of anesthesia efficacy and duration than lidocaine. The use of 4% Articaine efficacy and duration was about 55% more effective than 2% Lidocaine and Endo Ice® was 28% more reliable than EPT.
