1. The Ability of Biodentine™ of Guided Tissue Remineralization (GTR): Analysis Using SEM, EDX and TEM
Abstract Objective: To analyze the Biodentine™ capability in guided tissue remineralization. Material and Methods: Four premolar with two cavities per tooth of 3 mm depth were demineralized with EDTA 17% in shaking incubator at 37ºC temperature. After 7 days, the sample were washed with aquabidest then were soaked in 20 ml NaCl 1 M (pH 7.0) at 25ºC tem

2. The interaction of a naturally occurring membranous collagen with high-saline dye solutions – mechanistic features from unusual multi-step biosorption
ABSTRACT It is known that wastewaters containing dyes are very difficult to treat, since many dyes are stable and recalcitrant molecules. In this way, sorption may suitable for effectively remove dyes in this specific application field. In this work, a first approach for using polymeric membranous collagen of fish scales for sorption of saline methylene blue

3. Hydrogen Peroxide Induced Oxidative Damage on Mineral Density and Mechanical Properties of Bone
ABSTRACT Hydrogen peroxide is a common reactive oxygen species involved in the catalytic mechanism though it is toxic to cells due to its oxidative nature. This work investigates the effects of hydrogen peroxide induced oxidative damage on bone mineral density and mechanical properties of bone which is primarily a composite material composed primarily of col

4. New strategies to improve results of mesh surgeries for vaginal prolapses repair – an update
ABSTRACTThe use of meshes has become the first option for the treatment of soft tissue disorders as hernias and stress urinary incontinence and widely used in vaginal prolapse's treatment. However, complications related to mesh issues cannot be neglected. Various strategies have been used to improve tissue integration of prosthetic meshes and reduce related

5. Preparation and characterization of collagen microspheres for sustained release of steroidal saponins
Steroidal saponins are the major pharmacological constituents of ophiopogon japonicus which have been used to treat bone and joint diseases, nerve damage, and hematischesis for hundreds of years in China. The objective of this study was to investigate the therapeutic potential of collagen microspheres loaded with steroidal saponins as an inducer factor for s

6. The effect of carbon dioxide therapy on composite graft survival
PURPOSE: To investigate the effect of carboxytherapy in auricular composite grafts in rabbits. METHODS: An experimental study was conducted using 20 rabbits randomly assigned to a treatment group of carboxytherapy or a control group of saline solution. In each ear, a circular graft with 1.5 cm or 2 cm of diameter was amputated and reattached. Animals underwe

7. Synthesis of carbonated hydroxyapatite nanorods in liquid crystals
Syntheses of calcium phosphate nanoparticles, carried out in systems formed from surfactant, oil and water, have resulted in materials with promising possibilities for application. The calcium phosphate particles were synthesized using two different liquid crystals, formed from RenexTM, cyclohexane and a salts solution. The morphology of the nanoparticles sy

8. Efeito da armazenagem em NaOCl na degradação morfologica da interface adesiva e na resistencia de união em diferentes substratos / Effect of NaOCl storage on morphologic degradation of adhesive interface and bond strength in different substrates
The purpose of this in vitro study was to investigate the fast effect of the 10 % hypochrorite sodium storage in simulation to hydrolytic degradation and adhesive interface aged for long time, through to evaluate the bond strength of microtensile bond test. The 10% NaOCl solution used in short periods of time (hours) resulting in a significant decrease in bo

9. Avaliação da clorexidina na qualidade da camada híbrida de dentes decíduos
It has recently been observed that chlorhexidine presents the capacity to inhibit the matrix metalloproteinase. They were responsible for the collagen fibrils degradation. Therefore, the object of this study was to assess the use of chlorhexidine on the quality of the hybrid layer of healthy primary teeth. The mean dentinal surface of primary teeth was prepa

10. Compósito de colágeno com silicato e hidroxiapatita como material para endodontia / Collagen composite with silicate and hydroxyapatite as material for endodontic applications
In this work was prepared and characterized collagen composites with silicate and hydroxyapatite for pulp capping; post pulpotomy usage, as endodontic material. Even though materials for this purpose are available, in most case they suffer degradation in the repair zone when. Was used type I collagen in the form anionic mixed with silicate (white Portland ce

12. A functional-morphological study of the tidemark region of articular cartilage maintained in a non-viable physiological condition.
Composite samples consisting of articular and calcified cartilage maintained in a non-viable physiological condition have been subjected to static compression using a system of simultaneous micromechanical testing and interference light microscopy. This, combined with transmission electron microscopy following glutaraldehyde fixation of the tissue under sust
