Articaine buccal infiltration versus lignocaine inferior alveolar block for pulpal anaesthesia in mandibular second premolars – Randomized control double blinded clinical trial

Abstract

IntroductionThe study was designed as a randomized double blinded cross over trial comparing the anaesthetic efficacy of buccal infiltration of 4% articaine with 1:100,000 epinephrine with that of 2% lignocaine with 1:200,000 epinephrine in inferior alveolar nerve block in mandibular second premolars. MethodsThe study was designed as a cross over trial. Each subject received both the anaesthetic agent and the order of anaesthetic administration was randomized. All the subjects received 1.8ml of articaine with 1:100,000 epinephrine in buccal infiltration and 1.8ml of 2% lignocaine with 1:200,000 epinephrine in inferior alveolar nerve block in an interval of one week. Pulp sensibility measures were recorded using an electric pulp tester. Data was analyzed using SPSS version 22. ResultsAmong the 46 subjects who completed the trial, 82.6% showed successful anaesthesia following articaine buccal infiltration compared with 89.1% following lignocaine inferior alveolar nerve block. There was no statistically significant difference between the success rates of 4% articaine buccal infiltration and 2% lignocaine IANB. ConclusionsStudy concluded that the buccal infiltration of 4% articaine can be used as a viable alternative anaesthetic technique for inferior alveolar nerve block of 2% lignocaine in mandibular second premolars.
