1. Effects of different desensitizing treatments on root dentin permeability
Abstract The objective of this study was to evaluate the effects of diode laser and a desensitizing dentifrice on dentin permeability. Fifty-two root dentin fragments were obtained (5 × 5mm) and treated with 24% EDTA gel. The samples were divided into 4 groups (n = 13): G1, control (no treatment); G2, diode laser (λ = 908 nm, 1.5 W, continuous mode, 20s);

2. Effect of desensitizing toothpastes on dentin
The objective of this study was to analyze the effects of toothbrushing with desensitizing toothpastes on dentin permeability and dentinal tubule occlusion. Fifty rats provided two hundred incisor teeth divided into five groups: DW, brushed with distilled water (control); FT, brushed with fluoride toothpaste; SCT, brushed with strontium chloride toothpaste;

3. Análise qualiquantitativa da permeabilidade dentinária do terço apical de diferentes grupos dentais / Qualiquantitative analysis of apical dentin permeability in different dental groups
This ex vivo study evaluated histochemically the dentin permeability of the root canal walls in the apical third of different human dental groups, analyzing the pattern of dentinal tubule distribution and the presence of sclerotic dentin in this region. Eighty teeth were used, being 8 of each dental group - maxillary and mandibular central incisors, lateral

4. Avaliação histoquímica da permeabilidade dentinária, após a utilização do EDTA como auxiliar na irrigação do canal radicular.
O presente estudo avaliou a permeabilidade dentinária em toda extensão do canal radicular, após a irrigação com hipoclorito de sódio associado ou não ao EDTA. Foram utilizados cinqüenta incisivos bovinos unirradiculares, de similar idade e anatomia, divididos em cinco grupos experimentais de acordo com as referidas soluções: NaOCl 1% -G1, NaOCl 1%

5. In vitro fluid filtration evaluation of intracoronal sealing ability of three materials used as secondary barrier / Avaliação in vitro da capacidade de selamento coronário de três materiais usados como barreira adicional, em dentes tratados endodonticamente, obturados com diferentes cimentos endodônticos, utilizando o método de filtração de fluído
Great part of endodontic treatment fails because of failures in provisory or definitive restoration, permiting a coronal microleakage. For these reasons, in last years, there is a preocupation in sealing intra-coronal cavity after the treatment, to have in view a longer longevity. So many materials are being used for this purpose. Recently it has been develo

6. Avaliação dos efeitos do laser de Er,Cr:YSGG sobre superfícies radiculares expostas no tratamento da hipersensibilidade dentinária cervical. Estudo in vitro e in vivo / Desensitizing effects of Er:YAG and Er,Cr:YSGG lasers on dentin hypersensitivity. An in vitro and in vivo study
The aim of the present study was to determine the correct parameters of the Er,Cr:YSGG laser in the treatment of cervical dentin hypersensitivity. This work was presented in 3 different stages. In the first one, it was evaluated the decrease in dentin permeability of dentinal tubules after Er,Cr:YSGG laser irradiation in radicular surfaces. Ninety premolars

7. Effects of a potassium oxalate gel/adhesive agent combined application on dentin permeability: an in vitro study / Avaliação in vitro dos efeitos da aplicação de sistemas adesivos, do oxalato de potássio, ou a combinação de ambos, na permeabilidade dentinária
There is an ongoing trend to move away from classical multi-component bonding systems toward simplified adhesives. An immediate consequence of adhesive simplification is the intrinsic permeability to water that result from their increase in hydrophilicity. Current studies have demonstrated that single-step adhesives may act as semi-permeable membranes that a
