1. Combined therapy with mineral trioxide aggregate, and guided tissue regeneration for a large radicular cyst: a 13-year follow-up
Biomaterials such as membrane barriers and/or bone grafts are often used to enhance periapical new bone formation. A combination of apical surgery and these biomaterials is one of the latest treatment options for avoiding tooth extraction. In case of periapical lesions, guided tissue regeneration (GTR) is attempted to improve the self-regenerative healing pr

2. Avaliação da regeneração óssea, sob a influência do laser de baixa intensidade, na região da sutura palatina de ratos após expansão da maxila / Evaluation of osseous regeneration, using the low-power laserterapy in the midpalatal suture in rats after maxillary expansion
Rapid maxillary expansion is one of the therapy used in the practice orthodontic to the posterior crossbite correction. Relapsed after expansion treatment required a contention device to guarantee a success therapy. The neoformation suture and the maxilla have maintained in the new position for a period to get the stability. To accelerate the osseous regener

3. Avaliação in vivo de matrizes tridimensionais de quitosana para a bioengenharia tecidual óssea.
This study evaluated the histomorphological behavior in vivo of tridimensional matrices of chitosan with 4% and 15% degrees of acetylene process, in a 9mm critical size defect of diameter created in rat calvaria. Sixty rats Wistar Albinus, disposed in three groups were evaluated. In the GI group (control group) the defect was filled only with blood coagulant

4. Mineralização in vitro de matrizes de colágeno aniônico derivadas de tecidos biológicos / In vitro mineralization of anionic collagen matrices
The reconstruction of osseous defects is still a problem that affects millions of people and medicine tries to solve it. One alternative to solve these problems has been the development of biomaterials that can be used as inductors in the osseous repair process. Collagen is a natural polymer able to promote healing and bone regeneration, and among hydroxyapa

5. Compósitos de hidroxiapatita e polihidroxibutirato em defeitos ósseos experimentais na ulna de coelhos / Hydroxyapatite-polyhydroxybutyrate composites in experimentally made bone deffects in rabbits ulna
Biomaterials used today to treat bones defects and fractures still bear some deficiencies to be corrected. This study is a preliminary analysis of composites made of hydroxyapatite (HAP-91) and polyhydroxybutyrate (PHB) essentials characteristics to be used in orthopedics. The composites were studied in osseous defects concerning their biocompatibility, osse

6. THE APPLICATION OF MESENCHYMAL STEM CELLS CULTURED IN THE PRESENCE OF FGF-2 FOR THE REPAIR OF OSSEOUS DEFECTS IN RATS / APLICAÇÃO DE CÉLULAS-TRONCO MESENQUIMAIS CULTIVADAS COM FGF-2 NA REGENERAÇÀO ÓSSEA DE RATOS
There is considerable interest in the therapeutic use of mesenchymal stem cell (MSC) implantation to repair osseous defects. A basic requirement for the application of such strategy is the obtention of MSCs in sufficient numbers, which may be directly influenced by the culture conditions used for expansion of the population. Although there are a number of st

7. Avaliação clinica do tratamento de lesões de bifurcação grau II com membranas de politetrafluoroetileno expandido associadas a exertos de mistura ossea
Este estudo foi delineado para avaliação clínica, em humanos, do tratamento de lesões de bifurcação grau II inferiores pela técnica de regeneração tecidual guiada associada a enxerto ósseo autógeno. Completaram o experimento 9 pacientes adultos que apresentavam 16 lesões de bifurcação grau II em molares inferiores. Foram avaliados os parâmetro

8. Alterações histologicas no periodonto de ratos frente ao trauma oclusal e doença periodontal
There are many different points of view on the trauma occlusion influence in periodontal disease. This research paper has the aim of verifying the histological alterations in the periodonto in rats as the consequence of a trauma occlusion and a periodontal disease. For this. purpose, 60 male rats were made used of having a weight ranging from 200 to 250 gram
