CONTEXT Deep neck infections have high potential for severe complications and even death, if not properly managed. The difference between clinical and computed tomography findings may demonstrate that clinical evaluation alone underestimates disease extent, which may lead to conservative treatment with worse prognosis. OBJECTIVE To compare clinical and(More)
A time lagged recurrent neural network (TLRN) was implemented to model the dynamic relationship between arterial blood pressure (ABP) and cerebral blood flow velocity (CBFV) and its performance was compared to classical linear model such as transfer function analysis, Aaslid's dynamic autoregulation model, and the Wiener-Laguerre moving average filter. A(More)
OBJECTIVE To determine whether bacterial biofilms are present on pediatric tracheotomy tubes. DESIGN Prospective observational series. INTERVENTIONS Eleven tracheotomy tubes removed during routine tracheotomy tube changes were analyzed for biofilm and live bacteria presence using confocal microscopy and vital stains. The external and internal surfaces(More)
The aim of this study was to evaluate the microtensile bond strength (µTBS) of two substrates (enamel and dentin) considering two study factors: type of composite resin [methacrylate-based (Filtek Supreme) or silorane-based (Filtek LS)] and aging time (24 h or 3 months). Twenty human molars were selected and divided into 2 groups (n=10) considering two(More)
OBJECTIVE To identify factors associated with self-perceived oral health among Brazilian elderly individuals. METHODS Data from the Projeto SB Brasil (Brazilian Oral Health Project), conducted in 2002-2003, were used. A probabilistic sample of 5,349 elderly individuals, aged between 65 and 74 years, was analyzed, interviewed and subsequently grouped into(More)
This study evaluated the sealing ability of gray MTA-Angelus mixed with propyleneglycol in furcal perforations using a bacterial leakage test. Furcal perforations were created in 30 human mandibular molars using a size 3 round bur The samples were divided randomly into 2 experimental groups (n=10) according to the mixing agent. In G1, the MTA powder was(More)
OBJECTIVE We calculated the prevalence and studied the factors associated with hepatitis B vaccination. Reasons for non-vaccination among dentists were investigated. METHODS A cross-sectional study was performed in Montes Claros, Minas Gerais, from 2007 to 2008, to assess hepatitis B vaccination among practicing dental surgeons. Variables were evaluated(More)
Several studies have shown that cochlear implants may reduce or even eliminate tinnitus in patients with bilateral profound hearing loss. However, there are not consistent references regarding ipsilateral tinnitus compared to unilateral profound hearing loss. The aim of this paper is to describe audiological results of a patient with asymmetrical hearing(More)
