Clinical evaluation of anesthetic efficacy of 2% lignocaine versus 4% articaine intraligamentary injection using StarPen after an ineffective inferior alveolar nerve block in mandibular molars with acute irreversible pulpitis: A randomized clinical trial
Inferior alveolar nerve block (IANB) frequently fails in teeth with acute irreversible pulpitis. Supplementary anesthetic technique is required in such cases to achieve profound anesthesia. This randomized single-blind controlled trial evaluated and compared the anesthetic efficacy of 2% lignocaine versus...
