Abstrakt: The objective of this study was to compare the effectiveness of buffered and non-buffered local anaesthetic (LA) following inferior alveolar nerve block (IANB). This study was conducted at Usmanu Danfodiyo University Teaching Hospital Sokoto from June 2020 to January 2021. Subjects were randomised into Groups A and B. Group A received 2 ml of freshly prepared 2% lignocaine with 1:100,000 adrenaline buffered with 0.18 ml of 8.4% sodium bicarbonate solution while those in Group B received non-buffered 2% lignocaine with 1:100,000 adrenaline LA solutions. The onset of action of the LA was assessed by subjective and objective methods, while pain at the injection site was assessed using a numerical rating scale. Data obtained were analysed using statistical package for social sciences (IBM SPSS) version 21. The mean (SD) ages for Groups A and B were 37.4 (14.9) and 40.1 (14.4) years, respectively. The mean (SD) onset times of the LA by subjective testing were 126 (31.7) and 201 (66.8) seconds for Groups A and B, respectively. Similarly, the mean (SD) onset times of the local anaesthesia by objective testing for Groups A and B were 186 (41.0) and 287 (85.0) seconds, respectively, and both were significant (p<0.001). Pain at the injection site assessed objectively and subjectively were also statistically different (p<0.001). The findings of this study suggest that buffered LA is more effective than non-buffered LA of the same composition when used for IANB particularly concerning a significantly faster rate of onset and less pain at the injection site.
