Rev. saúde pública; 50 (supl.2), 2016
ABSTRACT OBJECTIVE To analyze variations in the prevalence of chronic use of medicines by older adults in Brazil according to its possible association with the most prevalent chronic diseases and demographic and health factors, and to identify risk factors for polypharmacy. METHODS A study based on d...

Tissue characterization following revascularization of immature dog teeth using different disinfection pastes

Braz. oral res. (Online); 30 (1), 2016
Abstract Revascularization of immature teeth with necrotic pulps traditionally involves the use of triple antibiotic paste, which may sometimes lead to undesirable complications. The objective of this study was to assess tissue repair in immature dog teeth with apical periodontitis subjected to revascula...

Chitosan-collagen biomembrane embedded with calcium-aluminate enhances dentinogenic potential of pulp cells

Braz. oral res. (Online); 30 (1), 2016
Abstract The development of biomaterials capable of driving dental pulp stem cell differentiation into odontoblast-like cells able to secrete reparative dentin is the goal of current conservative dentistry. In the present investigation, a biomembrane (BM) composed of a chitosan/collagen matrix embedded w...

Effect of new innovative restorative carbomised glass cement on intrapulpal temperature rise: an ex-vivo study

Braz. oral res. (Online); 30 (1), 2016
Abstract This study aimed to evaluate the temperature changes that occurred in the pulp chamber when using GCP Glass Carbomer Fill (GCP) and two different resin-modified glass-ionomer (RGI) restorative materials at different dentin thicknesses. A standardized Class I occlusal cavity with 1 mm or 2 mm den...

Antimicrobial activity and substantivity of Uncaria tomentosa in infected root canal dentin

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to analyze the antimicrobial activity and substantivity of Uncaria tomentosa Willd DC (cat's claw, CC) in root dentin contaminated with Enterococcus faecalis. Forty-eight human premolars were contaminated with E. faecalis (ATCC 29212) and randomly divided into four grou...

Antiseptics and microcosm biofilm formation on titanium surfaces

Braz. oral res. (Online); 30 (1), 2016
Abstract Oral rehabilitation with osseointegrated implants is a way to restore esthetics and masticatory function in edentulous patients, but bacterial colonization around the implants may lead to mucositis or peri-implantitis and consequent implant loss. Peri-implantitis is the main complication of oral...

Aged garlic extract and S-allylcysteine prevent apoptotic cell death in a chemical hypoxia model

Biol. Res; 49 (), 2016
BACKGROUND: Aged garlic extract (AGE) and its main constituent S-allylcysteine (SAC) are natural antioxidants with protective effects against cerebral ischemia or cancer, events that involve hypoxia stress. Cobalt chloride (CoCl2) has been used to mimic hypoxic conditions through the stabilization of the...

Shenhua Tablet inhibits mesangial cell proliferation in rats with chronic anti-Thy-1 nephritis

Biol. Res; 49 (), 2016
BACKGROUND: In China, mesangial proliferative glomerulonephritis (MsPGN) is one of the most common kidney diseases. In this study, we treated a rat model of chronic anti-Thy-1 MsPGN with Shenhua Tablet and evaluated whether the tablet was able to protect the kidney function. Thirty-six Wistar rats were r...
