Randomized Controlled Trial Comparative Study
The efficacy of three desensitizing agents used to treat dentin hypersensitivity.
In a single-center, double-masked, split-mouth-designed, clinical short-term trial, the authors assessed the clinical responses of teeth with dentin hypersensitivity (DH) after treating the teeth with one of three desensitizing agents across four weeks. ⋯ The study results should be considered with caution, as it is not clear how many of the pain relief effects were related to the natural desensitization of teeth over time.

Randomized Controlled Trial Comparative Study
A comparison of the local anesthetic efficacy of the extraoral versus the intraoral infraorbital nerve block.
The efficacy of the extraoral infraorbital nerve block has not been studied sufficiently to ensure its appropriate clinical use. To compare the local anesthetic efficacy of the extraoral versus the intraoral infraorbital nerve block, the authors conducted a prospective, randomized crossover study. ⋯ Both nerve blocks would be ineffective in the central and lateral incisors. Both nerve blocks would be somewhat successful in the canine and premolars but not in the first molar.

Randomized Controlled Trial
Virtual reality distraction for pain control during periodontal scaling and root planing procedures.
Although pain management during periodontal treatment usually is achieved with anesthesia, alternative methods are available. The authors conducted a study to evaluate the analgesic effect of immersive virtual reality (VR) during periodontal scaling and root planing (SRP) procedures. ⋯ Practitioners can use immersive VR distraction for pain control during SRP procedures.

Randomized Controlled Trial Comparative Study
The efficacy of six local anesthetic formulations used for posterior mandibular buccal infiltration anesthesia.
The authors conducted a randomized, double-blind clinical trial to evaluate pulpal anesthesia achieved after mandibular infiltration of five commonly marketed dental local anesthetic formulations as compared with a control formulation of lidocaine with epinephrine. ⋯ The authors found that mandibular infiltration with 0.9 mL of the tested dental anesthetics could induce only partial pulpal anesthesia, a level likely to be inadequate for most dental procedures. When compared with L100, only the A100 induced statistically greater pulpal anesthesia after mandibular buccal infiltration.

Flumazenil reversal of sublingual triazolam: a randomized controlled clinical trial.
Incremental sublingual (SL) dosing of triazolam has emerged as a popular sedation technique. Nevertheless, few studies have evaluated the technique's safety or efficacy. Given its popularity, an easily administered rescue strategy is needed. ⋯ A single intraoral injection of flumazenil (0.2 mg) cannot immediately reverse oversedation with triazolam. A higher dose might be effective. Reversal for the purpose of discharging the patient early is neither appropriate nor safe.
