Randomized Controlled Trial Comparative Study Clinical TrialA pilot study comparing ketoprofen and acetaminophen with hydrocodone for the relief of postoperative periodontal discomfort.
The aim of this study was to compare ketoprofen to acetaminophen with hydrocodone (A/H) in a postoperative periodontal pain model. A double-blind protocol was used. Thirty minutes prior to each procedure, subjects were given orally either 100 mg ketoprofen or a placebo tablet. ⋯ A/H provided significantly better pain relief at Hours 5 and 6, while overall discomfort levels were significantly higher with ketoprofen than with placebo at Hours 3 and 4. Pain levels were low for both groups. It is recommended that additional analgesics for mild to moderate pain should be tested.

Timing and side effects of flumazenil for dental outpatients receiving intravenous sedation with midazolam.
We studied the timing and side effects of flumazenil treatment for 10 healthy volunteers and 46 dental outpatients who received intravenous sedation with midazolam. For the volunteers, vital signs were monitored before and after intravenous injection of midazolam and flumazenil. In addition, grip strength, signs and symptoms, and performance on the Romberg's test and addition tests were evaluated 30 min and 60 min after midazolam injection as well as after flumazenil injection. ⋯ One patient in group S had drowsiness that did not resolve after injection of flumazenil and continued until the following day. Our results indicate that flumazenil should be given at least 60 min after intravenous sedation with midazolam in dental outpatients. Moreover, caution should be exercised with regard to the potential side effects of flumazenil.

Plasma concentrations of lidocaine and prilocaine were measured following the application of a 5% eutectic mixture of local anesthetics (EMLA) topical anesthetic cream to the oral mucosa of twelve subjects. For each subject, a total of 8 g of EMLA was occluded to 18 cm2 of buccal mucosa for 30 min. ⋯ No adverse local effects were observed from a 30-min application of EMLA. A follow-up pilot study assessing the clinical efficacy of EMLA for achieving sufficient analgesia for restorative procedures showed that the cream was successful in 75% of subjects tested.

Meta Analysis Comparative StudyThe efficacy of nonopioid analgesics for postoperative dental pain: a meta-analysis.
The evidence for the efficacy of nonopioid analgesics in the dental pain model was examined by conducting a meta-analysis. Studies were obtained by searching the literature from August 1996 back to 1975 using the terms pain, analgesics, and dentistry. This led to the review of 294 articles, of which 33 studies met the inclusion criteria. ⋯ Collectively, therapeutic doses of the nonsteroidal anti-inflammatory drugs (NSAIDs) commonly used in dentistry were significantly more efficacious than the combination of acetaminophen (600 or 650 mg) with codeine (60 mg). Similarly, specific doses of each of diflunisal, flurbiprofen, ibuprofen, and ketorolac were significantly more efficacious than the commonly used acetaminophen-codeine combination. These quantitative results show that particular NSAIDs may be more efficacious than the acetaminophen-codeine combination for relief of postoperative dental pain.

Randomized Controlled Trial Comparative Study Clinical TrialAvoidance of nitrous oxide and increased isoflurane during alfentanil based anesthesia decreases the incidence of postoperative nausea.
Postoperative nausea and vomiting have been associated with the use of nitrous oxide. Alfentanil, when combined with nitrous oxide, also results in a high incidence of postoperative nausea and vomiting. To further define this emesis-potentiating effect of N2O, 119 patients were chosen for study and divided into two groups: group A (n = 59) was administered a mixture of alfentanil, N2O, and O2 with 0.25% isoflurane, group B (n = 60) was administered a mixture of oxygen, room air, isofluorane, and alfentanil. ⋯ The incidence of vomiting was 5% (3/60) in group B and 15% (8/59) in group A (P = 0.067). Forty-four percent (26/59) of the patients in group A and 20% (12/59) in group B were nauseated postoperatively (P = 0.005). Our data suggest that elimination of N2O from alfentanil-based anesthetics lessens the incidence of nausea.
