Efficacy of buccal infiltration anaesthesia with articaine for extraction of mandibular molars: a clinical trial

It is hard to provide adequate anaesthesia by infiltration of lidocaine into the mandible because of the thick buccal cortex. An inferior alveolar nerve block is often used but has a high failure rate, which has led research workers to look for an anaesthetic agent that will anaesthetise the lower teeth by buccal infiltration alone. We have assessed the efficacy of buccal infiltration anaesthesia with articaine by designing a double-blind controlled clinical trial in 133 patients who required extraction of mandibular molars.
