Randomized Controlled Trial Comparative StudyEffect of dexmedetomidine injected into the oral mucosa in combination with lidocaine on local anesthetic potency in humans: a crossover double-blind study.
Recently, attention has been paid to dexmedetomidine, a selective α-2 adrenoceptor agonist, as a possible additive for local anesthesia. However, the effect of locally injected dexmedetomidine on the anesthetic action in humans has not fully been clarified. Thus, the purpose of the present study was to evaluate the effect of dexmedetomidine injected into the oral mucosa in combination with lidocaine on local anesthetic potency in humans. ⋯ The present study showed that a combination of dexmedetomidine plus lidocaine considerably enhances the local anesthetic potency of lidocaine without any major influences on the cardiovascular system when locally injected into the oral mucosa.

Review Meta AnalysisImproved apnea-hypopnea index and lowest oxygen saturation after maxillomandibular advancement with or without counterclockwise rotation in patients with obstructive sleep apnea: a meta-analysis.
This study investigated whether patients with obstructive sleep apnea (OSA) who undergo maxillomandibular advancement (MMA) with counterclockwise (CCW) rotation compared with those who undergo MMA without CCW rotation have better outcomes. ⋯ CCW-MMA or MMA in patients with OSA results in a statistically meaningful decrease in postoperative AHI and a statistically meaningful increase in postoperative LSAT.

Review Meta Analysis Comparative StudyLocal versus general anesthesia for the management of nasal bone fractures: a systematic review and meta-analysis.
The aim of this study was to answer the following question: in patients with nasal bone fractures (NBFs), does closed reduction under local anesthesia (LA) produce comparable outcomes as closed reduction under general anesthesia (GA)? ⋯ Regardless of the cost and risks associated with GA, the results of the meta-analysis showed that GA provides better patient satisfaction with anesthesia, appearance and function of the nose, and preference of treatment for a refracture of the nose. In addition, the meta-analysis showed that GA decreased the number of subsequent corrective surgeries (septoplasty, septorhinoplasty, and rhinoplasty) required.

Randomized Controlled Trial Comparative StudyA double-blind randomized study evaluating the effect of intra-alveolar chlorhexidine gel on alveolar osteitis after removal of mandibular third molars.
The main purpose of the present investigation was to determine whether intra-alveolar chlorhexidine (CHX) gel is an effective preventative treatment for alveolar osteitis (AO), as has been strongly suggested by previous investigators. Another goal was to evaluate whether there is a correlation between the use of analgesics during the postoperative week and the development of AO, a correlation that could be a supplement to the commonly used diagnostic criteria for AO. ⋯ The present study did not verify that application of CHX gel improves healing after removal of impacted third molars. The patients' postoperative analgesic intake reflected the development of AO.

Randomized Controlled Trial Comparative StudyEffect of low-level laser therapy on adolescents with temporomandibular disorder: a blind randomized controlled pilot study.
The aim of this pilot study was to evaluate the effect of low-level laser therapy on pain, mandibular movements, and occlusal contacts in adolescents and young adults with temporomandibular disorder. ⋯ No statistically significant differences were found regarding pain, mandibular range of motion, or the distribution of occlusal contacts after treatment with low-level laser therapy. These preliminary results need to be verified in a larger sample of patients to confirm the lack of response to low-level laser therapy.
