Sistema adesivo universal: análise da interface adesiva e degradação colagenolítica em dentina submetida à diferentes protocolos de condicionamento ácido

O objetivo desse estudo foi analisar a interface adesiva do sistema adesivo Single Bond Universal (SBU) em dentina submetida à diferentes protocolos de condicionamento ácido em 24 h e 12 meses. E a degradação colagenolítica (DC) mediada por metaloproteinases (MMPs) e Catepsina-K (CAT-K) em tempo ime...

Histomorphometric analysis of the skin of women during the reproductive period

Clinics; 73 (), 2018
OBJECTIVES: The aim of this study was to evaluate the histomorphometry of the skin of women during the reproductive period according to the Fitzpatrick classification. METHODS: Thirty women aged 30 to 45 years were included in this study. We studied the surgical sites of extracted nevi. The material was...

Influence of ethanol-wet dentin, adhesive mode of application, and aging on bond strength of universal adhesive

Abstract The aim of this study was to evaluate the effect of ethanol on the bond longevity of a universal adhesive system to bovine dentin, under different modes of adhesive application and artificial aging. Bovine dentin was exposed, and the smear layer was standardized by sandpaper polishing. Specimens...

Effect of acute administration of nicotine and ethanol on tooth movement in rats

Abstract The aim of this study was to evaluate the effect of acute administration of nicotine and ethanol on tooth movement in rats. Two hundred rats were divided into eight groups: S: saline; N: nicotine; E: ethanol; NE: nicotine and ethanol; SM: saline with tooth movement; NM: nicotine with tooth movem...

An in vitro investigation and comparison of the mechanical properties of human amnion and bovine collagen membrane

Periodontia; 28 (4), 2018
Introduction: The human amnion membrane is now increasingly used in Guided Tissue Regeneration(GTR). These placental allografts have excellent biologic properties. There is limited information regarding their mechanical properties as compared to other collagen membranes used in GTR. The aim of this study...

Morphological changes in rat rectus abdominis muscle induced by diabetes and pregnancy

Braz. j. med. biol. res; 51 (4), 2018
The urethral muscle of diabetic pregnant rats is affected by long-term mild diabetes and short-term severe diabetes, which plays a crucial role in the pathogenesis of pelvic floor disorders. We hypothesized that muscles outside the pelvis are subject to similar changes. The current study aimed at analyzi...

Extracellular matrix and fibroblast injection produces pterygium-like lesion in rabbits

Biol. Res; 51 (), 2018
BACKGROUND: Translational research to develop pharmaceutical and surgical treatments for pterygium requires a reliable and easy to produce animal model. Extracellular matrix and fibroblast are important components of pterygium. The aim of this study was to analyze the effect of the subconjunctival inject...

Decellularization of placentas: establishing a protocol

Braz. j. med. biol. res; 51 (1), 2018
Biological biomaterials for tissue engineering purposes can be produced through tissue and/or organ decellularization. The remaining extracellular matrix (ECM) must be acellular and preserve its proteins and physical features. Placentas are organs of great interest because they are discarded after birth ...
