Local anaesthesia or numbing is done before tooth extraction. This study compares two different methods of numbing molar teeth before extraction. It compares them on the basis of pain during the procedure and on discomfort after the procedure as well. It will help dentists better understand the benefits of the two techniques, and their usage case to case.
The study was designed as a randomized controlled trial. The purpose of this study was to examine the differences in efficacy of the intraligamentary anaesthetic technique and the inferior alveolar nerve block for mandibular posterior tooth extraction cases. Pain intensity, duration of anaesthesia, incidence of post-operative dry socket, success rates, onset of anaesthesia were examined. It was done in a split-mouth method so that two different techniques were used in the same patient, thus minimizing individual variations.
