Comparative Evaluation Of Anaesthetic Efficacy Of warm, Buffered And Conventional 2% Lignocaine For The Success Of Inferior Alveolar Nerve Block In Mandibular Primary Molars- A Randomized Clinical Controlled Trial.

This study is a randomized, double blinded, split mouth clinical trial, comparing the anaesthetic efficacy and patient’s pain reaction to warm lignocaine, buffered lignocaine and conventional 2% lignocaine during pulp therapy in primary mandibular molars. 50 patients were randomly divided into 2 groups and were given conventional lignocaine on one visit on one side and either buffered or warmed lignocaine on the other side during the next visit. The results showed that the pain on administration, mean onset of anaesthesia, pain during pulp therapy, the parameters of the SEM score and the duration of anaesthesia were all significantly lower for the buffered and warmed solutions compared to the conventional solution. However there was no significant difference on comparing the warmed and buffered groups with each other. Thus it can be concluded that modifying local anaesthesia by either buffering it or warming it can be beneficial in reducing the pain on injection and during pulp therapy, especially in children.
