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.
