Randomized Controlled Trial Meta Analysis Clinical TrialTramadol and acetaminophen tablets for dental pain.
The purpose of this work was to compare the efficacy and time to analgesia of a new tramadol/acetaminophen combination tablet to those of tramadol or acetaminophen (APAP) alone. A meta-analysis was performed of 3 separate single-dose, double-blind, parallel-group trials in patients with moderate or severe pain following extraction of 2 or more third molars. Patients in each study were evenly randomized to a single dose of tramadol/APAP (75 mg/650 mg), tramadol 75 mg, APAP 650 mg, ibuprofen 400 mg, or placebo. ⋯ Median time to supplemental analgesia and mean overall assessment of efficacy were greater (P < .05) for the tramadol/APAP group (302 minutes and 3.0, respectively) than for the tramadol (122 minutes and 2.0) or APAP (183 minutes and 2.7) monotherapy groups. A new combination analgesic, tramadol/APAP, is superior to tramadol or APAP alone with respect to pain relief and duration of action. It is also superior to tramadol alone with respect to time to onset.

Randomized Controlled Trial Clinical TrialAnesthetic efficacy of a combination of hyaluronidase and lidocaine with epinephrine in inferior alveolar nerve blocks.
The purpose of this prospective, randomized, double-blind study was to determine the anesthetic efficacy of a buffered lidocaine with epinephrine solution compared to a combination buffered lidocaine with epinephrine plus hyaluronidase solution in inferior alveolar nerve blocks. Thirty subjects randomly received an inferior alveolar nerve block using 1 of the 2 solutions at 2 separate appointments using a repeated-measures design. Mandibular anterior and posterior teeth were blindly pulp tested at 4-minute cycles for 60 minutes postinjection. ⋯ There were no significant differences (P > .05) between the 2 solutions. However, the combination lidocaine/hyaluronidase solution resulted in a significant increase in postoperative pain and trismus. It was concluded that adding hyaluronidase to a buffered lidocaine solution with epinephrine did not statistically increase the incidence of pulpal anesthesia in inferior alveolar nerve blocks and, because of its potential tissue damaging effect, it should not be added to local anesthetic solutions for inferior alveolar nerve blocks.
