Endodontic anesthesia in mandibular molars: A clinical study

Sixty-one mandibular molar teeth with clinically manifest pulpitis, which required endodontic therapy, were studied. Twenty-seven subjects received standard inferior alveolar nerve block (IANB) with 2% lidocaine HCI with 1:100,000 epinephrine and 34 subjects received IANB with 3% mepivacaine with no...

Zusammenfassung:Sixty-one mandibular molar teeth with clinically manifest pulpitis, which required endodontic therapy, were studied. Twenty-seven subjects received standard inferior alveolar nerve block (IANB) with 2% lidocaine HCI with 1:100,000 epinephrine and 34 subjects received IANB with 3% mepivacaine with no vasoconstrictor. Pulpal anesthesia was assessed with dichlorodifluormethane (DDM). Subjects who gave a positive response to DDM were given a periodontal ligament injection with 2% lidocaine with 1:100,000 epinephrine. This study showed that 3% mepivacaine HCI is as effective as 2% lidocaine HCI in achieving pulpal anesthesia in mandibular molars with IANB. Of a total 61 IANB with lip anesthesia, 23 subjects required peridontal ligament injection to achieve a negative response to DDM. It was concluded that lip anesthesia is not a reliable indicator of pulpal anesthesia. The use of DDM is a reliable method of determining true pulpal anesthesia.
