Randomized Controlled TrialA prospective, randomized, double-blind comparison of 2% lidocaine with 1:100,000 and 1:50,000 epinephrine and 3% mepivacaine for maxillary infiltrations.
The purpose of this prospective, randomized, double-blind crossover study was to evaluate the anesthetic efficacy of 2% lidocaine with 1:100,000 and 1:50,000 epinephrine and 3% mepivacaine in maxillary lateral incisors and first molars. ⋯ Anesthetic success and the onset of pulpal anesthesia were not significantly different between 2% lidocaine with either 1:100,000 or 1:50,000 epinephrine and 3% mepivacaine for the lateral incisor and first molar. Increasing the epinephrine concentration from 1:100,000 to 1:50,000 in a 2% lidocaine formulation significantly decreased pulpal anesthesia of short duration for the lateral incisor but not the first molar. For both the lateral incisor and first molar, 3% mepivacaine significantly increased pulpal anesthesia of short duration compared with 2% lidocaine with either 1:100,000 or 1:50,000 epinephrine.

Brazilian HIV-infected population: assessment of the needs of endodontic treatment in the post-highly active antiretroviral therapy era.
The effects of highly active antiretroviral therapy (HAART) on the prevalence of endodontic diseases in HIV-infected individuals have not been reported. ⋯ We found that those HIV-infected individuals needing endodontic treatment had a lower CD4 + T-cell count, which probably correlated with a lower adherence to the HAART regimen.

Randomized Controlled TrialAnesthetic efficacy of supplemental buccal and lingual infiltrations of articaine and lidocaine after an inferior alveolar nerve block in patients with irreversible pulpitis.
The success rate of inferior alveolar nerve block (IANB) decreases in patients with irreversible pulpitis. It was hypothesized that supplemental infiltration of lidocaine and articaine may improve the success rates. ⋯ Although supplemental buccal and lingual infiltrations of 4% articaine or 2% lidocaine increased the success rate of the inferior alveolar nerve block in patients with irreversible pulpitis, none of the techniques provided acceptable success rates.

Spinal cord stimulation has been a therapeutic option for chronic pain for over 40 years. The neurostimulator (NS) is a device consisting of three primary components: an electrode array configured either as a paddle or wire; an implantable pulse generator (IPG) consisting of a minicomputer, a transceiver/antenna, an electrical generator, and a battery; and insulated wiring connecting the electrode to the IPG. The electrode array can be implanted into the epidural space overlying the dorsal spinal cord or along a peripheral nerve. ⋯ Two apex locators, two EPTs, and one electrocautery unit were tested. Seventy trials were used by each dental device on each tissue. Using the exact binomial method of determining confidence intervals, the probability of damage to the NS by any of the devices was negligible.

Case ReportsOsteonecrosis related to intraosseous anesthesia: report of a case.
Intraosseous anesthesia is an effective and increasingly used technique with few reported complications. The technique uses a specialized drill to perforate the osseous cortex where local anesthetic can then be deposited to anesthetize teeth. ⋯ Prolonged rotation of the perforator drills in the bone can also cause excessive heat, which can lead to bone necrosis. This report describes a case of focal osteonecrosis subsequent to intraosseous anesthesia and discusses possible etiologies of this sequela.
