Randomized Controlled Trial Comparative StudyMidazolam increases bite force during intravenous sedation.
Although there have been many reports on the effects of midazolam on vital function and the recovery profile, little is known about muscle power during sedation. The purpose of this study was to investigate the effects of midazolam on muscle power during moderate sedation. ⋯ Although the detailed mechanisms are unknown, bite force increases despite the muscle-relaxant action of midazolam during sedation and persists even with flumazenil reversal.

Microsurgical repair of the inferior alveolar nerve: success rate and factors that adversely affect outcome.
The objectives of this study were to determine the likelihood of regaining functional sensory recovery (FSR) after microsurgical repair of the inferior alveolar nerve (IAN), and which variables significantly affected the outcome of that surgery in a large series of patients. ⋯ Microsurgical repair of an IAN injury resulted in successful restoration of an acceptable level of neurosensory function (FSR) in most patients (152 of 186 repairs [81.7%]) in this study. The likelihood of regaining FSR was inversely related to both time between the injury and its repair and increasing patient age, with significant threshold drops at 12 months after nerve injury and at 51 years of age, respectively.

Comparative StudyFactors associated with hospitalization charges for cleft palate repairs and revisions.
The objective of this study is to provide nationally representative estimates of cleft palate correction and revision procedures performed in hospitalized patients, as well as to examine patient- and hospital-level factors associated with hospitalization charges. ⋯ This study identified an association between hospital charges and insurance payer, race, treatments performed, and age. Our results provide insights into nationally representative estimates on management of cleft palate corrections and revisions.

Dexmedetomidine dose dependently decreases oral tissue blood flow during sevoflurane and propofol anesthesia in rabbits.
The aim of the present study was to investigate the effect of dexmedetomidine (DEX) continuous infusion on blood flow in rabbit oral tissues during sevoflurane or propofol anesthesia. ⋯ Our findings suggest that infusion of DEX decreases TBF, BBF, MBF, UBF, and LBF in a dose-dependent manner without significant changes in systemic hemodynamic variables during sevoflurane or propofol anesthesia.
