1. In situ anticariogenic effect of conventional glass ionomer cement by dentrifice dependence / Efeito anticariogênico de cimento de ionômero de vidro convencional pela dependência de dentrifício: estudo "in situ"
The aim of this study was to assess in situ anticaries potential of conventional glass ionomer cement (GIC) to prevent enamel and dentine demineralization either alone or in combination with a fluoride (F) regimen. A randomized, blind, crossover design for caries induction was carried out in 2 phases of 14 days each. This study was a 2 x 2 cross-over factori

2. Potencial anticárie dos reservatórios de cálcio, fosfato e fluoreto do biofilme dental / Anticaries potential of calcium, phosphate and fluoride reservoirs of dental biofilms
Dental biofilm presents organic and inorganic reservoirs of calcium (Ca), phosphate (PI) and fluoride (F) that could act as a source of these ions to biofilm fluid during pH drops, reducing dental demineralization. Its still unknown the source responsible for the increase of such ions in biofilm fluid after pH drop, since they could be also derived from mi

3. Influence of ativation of self-etching adhesives systems on the microtensile bond strength and quality of hibrydization in dentin and enamel / Influencia da distancia da ativação dos sistemas adesivos autocondicionantes na resistencia de união e qualidade da hibridização em dentina e esmalte
The self-etching adhesives systems present high water content that are used as solvent for acid monomer ionization. The presence of the excess of this solvent in the hybrid layer can compromise its the formation, as well as to affect the polymerization of monomers producing bonding interfaces permeables. The use of self-etching adhesives in clinical situatio

4. AVALIAÇÃO DE ADESIVOS AUTOCONDICIONANTES SOBRE A UNIÃO ADESIVA EM ESMALTE E DENTINA
The purpose of this study was to evaluate of bond-strength of self-etching adhesives on the in enamel and dentine. Forty third-molars were used to produces a flat enamel and dentin surfaces for the adhesion procedures. The occlusal surfaces of teeth were sectioned perpendicular to the long axis of the tooth in order to expose a flat dentin surface. In enamel

5. "Influência do método de remoção de cárie na resistência adesiva de um sistema autocondicionante" / Microtensile bond strength of self-etching adhesives to caries-affected dentine
New methods for carious dentine removal have been proposed, such as, lasers and chemo-mechanical. This in vitro study aimed to evaluate the influence of caries removal methods (steel burs, Er, Cr: YSGG laser and Carisolv) on microtensile bond strength of self-etching adhesive systems. 50 extracted carious human molars were ground to expose flat surfaces wher

6. Influencia dos metodos de secagem da dentina na resistencia ao cisalhamento de sistemas adesivos
The aim of the present study was to evaluate the shear bond strength of two adhesive systems when applied to dentin with different degrees of wetness. Buccal, lingual and palatine surfaces of 105 intact third molars recently extracted and stored in 10% formaline were utilized. After conditioning with 35% acid phosphoric for 15 seconds, seven methods of dryin

7. In Situ Zymography and Immunolabeling in Fixed and Decalcified Craniofacial Tissues
In situ zymography is a very important technique that shows the proteolytic activity in sections and allows researchers to observe the specific sites of proteolysis in tissues or cells. It is normally performed in non-fixed frozen sections and is not routinely performed in calcified tissues. In this study, we describe a technique that maintains proteolytic a

8. Substrate influences rat osteoclast morphology and expression of potassium conductances.
1. We studied the electrophysiological properties of freshly isolated rat osteoclasts using the whole-cell configuration of the patch-clamp technique. Membrane currents were recorded from cells plated on three substates: dentine, type I collagen and glass. 2. Based on their morphology, we defined two categories of osteoclasts. 'Rounded' osteoclasts were dome
