2. Additive effect of pulp pequi oil (Caryocar brasiliense Camb.) on the biocompatibility of collagen and gelatin membranes in subcutaneous implants
RESUMO Trauma ou lesões causadas por doenças podem enfraquecer e degenerar os tecidos humanos e animais. O uso de biomateriais para reparação direta ou indireta surgiu como uma alternativa promissora e tornou-se um importante tema de pesquisa. O óleo de pequi (Caryocar brasiliense Camb.) mostrou propriedades antifúngicas, antibacterianas, anti-inflamat

3. HPLC-DAD PROFILE OF PHENOLIC COMPOUNDS, CYTOTOXICITY, ANTIOXIDANT AND ANTI-INFLAMMATORY ACTIVITIES OF THE AMAZON FRUIT Caryocar villosum
Piquiá (Caryocar villosum - Caryocaraceae) is a native fruit from the Amazon region rich in bioactive substances. Fruit pulp extracts were analyzed by HPLC, together with extracts obtained from fruit pulp industry residual parts, byproducts such as husks (shells) and seeds. Extracts were prepared with two ethanolic solvent systems. Phenolic substances ellag

4. Evaluation of the genotoxicity and mutagenicity of Ca3SiO5-based cement
Abstract Ca3SiO5 is new cement based on the composition of Portland that has been developed to have superior physicochemical and biological properties. In a clinical evaluation, the cement did not appear to have cytotoxic properties and allowed for the proliferation of pulp cells and gingival fibroblasts. However, no previous studies have evaluated the genot

5. Evaluation of an experimental rat model for comparative studies of bleaching agents
ABSTRACT Dental materials in general are tested in different animal models prior to the clinical use in humans, except for bleaching agents. Objectives To evaluate an experimental rat model for comparative studies of bleaching agents, by investigating the influence of different concentrations and application times of H2O2 gel in the pulp tissue during in-o

7. Analysis of radiopacity, pH and cytotoxicity of a new bioceramic material
AbstractObjective RetroMTA® is a new hydraulic bioceramic indicated for pulp capping, perforations or root resorption repair, apexification and apical surgery. The aim of this study was to compare the radiopacity, pH variation and cytotoxicity of this material to ProRoot® MTA.Material and Methods Mixed cements were exposed to a digital x-ray along with an

8. CCL3 and CXCL12 production in vitro by dental pulp fibroblasts from permanent and deciduous teeth stimulated by Porphyromonas gingivalis LPS
Objective: The aim of this study was to compare the production of the chemokines CCL3 and CXCL12 by cultured dental pulp fibroblasts from permanent (PDPF) and deciduous (DDPF) teeth under stimulation by Porphyromonas gingivalis LPS (PgLPS). Material and Methods: Primary culture of fibroblasts from permanent (n=3) and deciduous (n=2) teeth were established

9. Long-term cytotoxic effects of contemporary root canal sealers
Objectives The aim of the present study was to investigate the effects of root canal sealers on the cytotoxicity of 3T3 fibroblasts during a period of 5 weeks. Material and Methods Fibroblasts (3T3, 1×105 cells per well) were incubated with elutes of fresh specimens from eight root canal sealers (AH Plus, Epiphany, Endomethasone N, EndoREZ, MTA Fillapex,

10. Immunological characteristics of mesenchymal stem cells
Although bone marrow is the main source, mesenchymal stem cells have already been isolated from various other tissues, such as the liver, pancreas, adipose tissue, peripheral blood and dental pulp. These plastic adherent cells are morphologically similar to fibroblasts and have a high proliferative potential. This special group of cells possesses two essenti

11. Influência de materiais odontológicos na capacidade de resposta de fibroblastos cultivados de polpa dental humana / Influence of dental materials on the response capability of cultured fibroblasts from human dental pulp
The aim of the present study is to investigate the influence of dental materials (Single Bond, HEMA, Vitrebond, Ketac Molar e Dycal) in the inflammatory response of human dental pulp fibroblasts from permanent teeth in relation to inflammatory mediators expression. and production. Primary cultures were established from third molars pulp tissue. After the fou

12. Estudo in vitro da produção de quimiocinas e pró-colágeno I por fibroblastos de gengiva, ligamento periodontal e polpa dental humanos / In vitro study of chemokines and procollagen I by human gingival, periodontal ligament and dental pulp fibroblasts
Fibroblastos são as células mais numerosas encontradas nos tecidos orais como gengiva, ligamento periodontal e polpa dental. Além de exercerem função estrutural, estas células também desempenham papel importante na resposta imune destes tecidos através do reconhecimento de antígenos e produção de mediadores inflamatórios e citocinas.
