1. Effect of a novel bioceramic root canal sealer on the angiogenesis-enhancing potential of assorted human odontogenic stem cells compared with principal tricalcium silicate-based cements
Abstract Objective: This study evaluated the angiogenesis-enhancing potential of a tricalcium silicate-based mineral trioxide aggregate (ProRoot MTA), Biodentine, and a novel bioceramic root canal sealer (Well-Root ST) in human dental pulp stem cells (hDPSCs), human periodontal ligament stem cells (hPLSCs), and human tooth germ stem cells (hTGSCs). Methodo

2. Pulp Fibroblast Cell Apoptosis After Application of Hema Dentine Bonding Material with Ethanol and Water Solvent
Resumo Os principais materiais para adesão dentinária em restaurações de resina composta são o 2-hidroxietil metacrilato (HEMA). O HEMA possui propriedades físicas e químicas benéficas e estáveis, ainda que tóxicas. A adição de etanol ou água pode reduzir o efeito tóxico do HEMA. O solvente etanol possui uma menor capacidade de ligação H em c

3. In-office tooth bleaching with 38% hydrogen peroxide promotes moderate/severe pulp inflammation and production of ll-1β, TNF-β, GPX, FGF-2 and osteocalcin in rats
Abstract Objectives: To study the intensity of inflammatory infiltrate and production of interleukin-1β (ll-1β), tumor necrosis factor-β (TNF-β), fibroblast growth factor-2 (FGF-2), glutathione peroxidase (GPX), and osteocalcin in response to in-office tooth bleaching in rats. Material and Methods: Twenty male Wistar rats were randomized into four grou

4. Extracellular calcium increases fibroblast growth factor 2 gene expression via extracellular signal-regulated kinase 1/2 and protein kinase A signaling in mouse dental papilla cells
Abstract We previously reported that elevated extracellular calcium (Ca2+) levels increase bone morphogenetic protein 2 expression in human dental pulp (hDP) cells. However, it is unknown whether extracellular Ca2+ affects the expression of other growth factors such as fibroblast growth factor 2 (FGF2). Objective: The present study aimed to examine the effe

5. 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

6. Ação de diferentes cimentos endodônticos sobre a citotoxicidade e a produção de gelatinases em cultura de fibroblastos / Cytotoxic evaluation and up-regulation of gelatinases by root canal sealers in human fibroblast cells
Os cimentos endodônticos podem entrar em contato com os tecidos periapicais no momento da obturação, gerando uma inflamação transitória. Esta inflamação pode estar associada a uma degradação das proteínas da matriz extracelular pelas metaloproteinases da matriz (MMPs). Dessa forma, o objetivo deste estudo foi avaliar os efeitos de exposição de c

7. Comportamento de células pulpares humanas expostas ao TGFβ1 a ao aFGF em cultura
O propósito do presente estudo foi avaliar o comportamento de células pulpares humanas expostas ao TGFβ1 e ao aFGF, em cultura, nas seguintes concentrações: TGFβ1 a 1ng/mL, TGFβ1 a 5ng/mL, TGFβ1 a 1ng/mL + aFGF a 5ng/mL, TGFβ1 a 5ng/mL + aFGF a 5ng/mL e aFGF a 5ng/mL. Foi avaliada a morfologia celular, a atividade da fosfatase alcalina, através de

8. "Resposta de fibroblastos de polpa humanos submetidos a substâncias liberadas por capeadores pulpares diretos" / Human pulp fibroblasts response to substances leached from direct pulp capping materials
The purpose of the present study was to evaluate the cytotoxic effects of substances leached during the use of direct pulp capping materials, on human pulp fibroblasts. There were used cell culture mediums conditioned by the test materials, as follows: group I: control (fresh medium without conditioning); group II: calcium hydroxide cement; group III: bondin

9. Insertional Inactivation of pac and rmlB Genes Reduces the Release of Tumor Necrosis Factor Alpha, Interleukin-6, and Interleukin-8 Induced by Streptococcus mutans in Monocytic, Dental Pulp, and Periodontal Ligament Cells
Streptococcus mutans possesses different cell wall molecules, such as protein of the I/II family, the serotype f polysaccharide rhamnose glucose polymer (RGP), and lipoteichoic acid (LTA), which act as adhesins and modulins, allowing S. mutans to colonize teeth and cause dental caries and pulpitis. We tested several isogenic mutants of S. mutans defective in

10. Human Gingival Fibroblasts Rescue Butyric Acid-Induced T-Cell Apoptosis
We previously demonstrated that butyric acid, an extracellular metabolite from periodontopathic bacteria, induces cytotoxicity and apoptosis in murine thymocytes, splenic T cells, and human Jurkat T cells. In this study, we used a cell-to-cell interaction system to examine the contribution of gingival fibroblasts to the regulation of T-cell death induced by
