Influência de diferentes densidades de energia do laser de baixa intensidade em fibroblastos derivados da polpa de dentes decíduos

O objetivo deste trabalho foi comparar os efeitos de diferentes densidades de energia e irradiâncias do Laser de Baixa Intensidade (LBI), variando em função do tempo de irradiação e potência, na viabilidade e proliferação de fibroblastos derivados da polpa de dentes decíduos humanos (HPF). HPF f...

Human dental pulp stem cells transplantation combined with treadmill training in rats after traumatic spinal cord injury

Braz. j. med. biol. res; 49 (9), 2016
Spinal cord injury (SCI) is a disabling condition resulting in deficits of sensory and motor functions, and has no effective treatment. Considering that protocols with stem cell transplantation and treadmill training have shown promising results, the present study evaluated the effectiveness of stem cell...

Effect of EDTA on TGF-β1 released from the dentin matrix and its influence on dental pulp stem cell migration

Braz. oral res. (Online); 30 (1), 2016
Abstract: Bioactive molecules stored in dentin, such as transforming growth factor beta1 (TGF-b1), may be involved in the signaling events related to dental tissue repair. The authors conducted an in vitro evaluation of the amount of TGF-b1 released from dentin slices after treatment with 10% ethylenedia...

Medium modification with bone morphogenetic protein 2 addition for odontogenic differentiation

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate whether medium modification improves the odontogenic differentiation of human dental pulp stem cells (DPSC) in vitro and in vivo. DPSC isolated from human impacted third molar teeth were analysed for clusters of differentiation with flow cytometry. Odontogen...

In vivo performance of different scaffolds for dental pulp stem cells induced for odontogenic differentiation

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was designed to determine the in vivo performance of three different materials as scaffolds for dental pulp stem cells (DPSC) undergoing induced odontogenic differentiation. An odontogenic medium modified by the addition of recombinant human bone morphogenetic protein 2 was used in th...

Low-intensity laser phototherapy enhances the proliferation of dental pulp stem cells under nutritional deficiency

Braz. oral res. (Online); 30 (1), 2016
Abstract Dental trauma in immature permanent teeth can damage pulp vascularization, which leads to necrosis and cessation of apexogenesis. Studies on tissue engineering using stem cells from human exfoliated deciduous teeth (SHEDs) have yielded promising results. Laser phototherapy (LPT) is able to influ...

Immunohistochemical expression of TGF-β1 and osteonectin in engineered and Ca(OH)2-repaired human pulp tissues

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of the present study was to evaluate the expression of transforming growth factor-β1 (TGF-β1) and osteonectin (ON) in pulp-like tissues developed by tissue engineering and to compare it with the expression of these proteins in pulps treated with Ca(OH)2 therapy. Tooth slices we...

Caracterización estereológica de odontoblastos en pulpas dentarias humanas sanas y con pulpitis reversible

Int. j. morphol; 32 (1), 2014
La reacción y reparación dentinaria depende del número de odontoblastos. Los métodos para obtener estimaciones fiables sobre la cantidad de odontoblastos en la pulpa dental han sido subjetivos y sesgados, sobre todo al evaluar los cambios cuantitativos y la potencial capacidad reparativa en presencia...

Cambios histológicos en la pulpa dental, ocasionados por preparaciones protésicas empleando abrasivos de diamante vs carburo
Histological changes in dental pulp produced by dental preparation for prosthesis application, in comparison between reaming by diamond or carbide tips

Rev. sanid. mil; 49 (4), 1995
Este estudio se realizó en 30 dientes, todos terceros molares superiores, los cuales se prepararon con el método para aplicación de prótesis, para investigar daño pulpar. La pulpa como es sabido es un órgano sensible a cualquier agente externo; el tallado dental puede en alguna forma lesionar estru...
