OBJETIVO: Proponer una batería para evaluar el desarrollo motor para estudiantes de primer ciclo básico. METODOLOGÍA: se evaluó una muestra de 190 estudiantes, pertenecientes a tres establecimientos educacionales de la ciudad de Talca, Chile. El rango de edad oscila entre los 5 y 9 años de edad. RES...

Effects of artepillin C on model membranes displaying liquid immiscibility

Braz. j. med. biol. res; 52 (3), 2019
It has been hypothesized that the therapeutic effects of artepillin C, a natural compound derived from Brazilian green propolis, are likely related to its partition in the lipid bilayer component of biological membranes. To test this hypothesis, we investigated the effects of the major compound of green ...

Rapid, specific, and sensitive detection of the ureR_1 gene in Klebsiella pneumoniae by loop-mediated isothermal amplification method

Braz. j. med. biol. res; 52 (3), 2019
Klebsiella pneumoniae is one of the main pathogenic bacteria that causes nosocomial infections, such as pneumonia, urinary tract infection, and sepsis. Therefore, the rapid and accurate detection of K. pneumoniae is important for the timely treatment of infectious patients. This study aimed to establish ...

Effect of grape seed extract (GSE) on functional activity and mineralization of OD-21 and MDPC-23 cell lines

Abstract Recent studies on functional tissue regeneration have focused on substances that favor cell proliferation and differentiation, including the bioactive phenolic compounds present in grape seed extract (GSE). The aim of this investigation was to evaluate the stimulatory potential of GSE in the fun...

The effect of enamel matrix derivatives on root coverage: a 12-month follow-up of a randomized clinical trial

Abstract Subepithelial connective tissue grafts (SCTGs) with a coronally advanced flap (CAF) are accepted as the gold standard for covering denuded root surfaces. In recent years, enamel matrix derivatives (EMDs) have been used for their regenerative potential in periodontics. The aim of this split-mouth...

Validation of self-reported history of root canal treatment in a southern Brazilian subpopulation

Abstract The aim of this study was to assess self-reported history of root canal treatment (SRHRCT) as a method for detecting the presence of root canal treatment (RCT) and apical periodontitis (AP) in a southern Brazilian subpopulation. In this cross-sectional study, 136 military police officers from th...

New material perspective for endocrown restorations: effects on mechanical performance and fracture behavior

Abstract The aim of this study was to investigate the mechanical performance and the fracture behavior of endocrown restorations prepared using distinct restorative materials. A total of 42 sound molars with similar crown size and shape were cut at 2 mm above the cementoenamel junction and endodontically...

Iodoform Vs Calcium Hydroxide/Zinc Oxide based pastes: 12-month findings of a Randomized Controlled Trial

Abstract This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused b...

Effect of a resin-modified glass-ionomer with calcium on enamel demineralization inhibition: an in vitro study

Abstract We assessed the effect of a new coating material based on resin-modified glass-ionomer with calcium (Ca) in inhibiting the demineralization of underlying and adjacent areas surrounding caries-like lesions in enamel. The measures used were surface hardness (SH) and cross-sectional hardness (CSH)....

Addition of zirconium oxide to Biodentine increases radiopacity and does not alter its physicochemical and biological properties

J. appl. oral sci; 27 (), 2019
Abstract Objectives: To evaluate the radiopacity of Biodentine (BD) and BD associated with 15% calcium tungstate (BDCaWO4) or zirconium oxide (BDZrO2), by using conventional and digital radiography systems, and their physicochemical and biological properties. Materials and Methods: Radiopacity was eval...
