1. β-Tricalcium phosphate shaped by replica method
Resumo Biomateriais, como o fosfato tricálcico, podem apresentar diferentes taxas de reabsorção no organismo que dependem das suas propriedades físico-químicas sendo que a condição superficial, tais como morfologia, tamanho de partículas e porosidade, é de fundamental importância. Assim, neste trabalho, estudou-se o recobrimento da matriz Luffa cyl

2. Tomographic late evaluation of xenogeneic bone grafts in sockets of impacted third molars
Abstract It is necessary to preserve height and thickness of the alveolar bone to facilitate rehabilitation with osteointegratable implants or simply to maintain bone integrity after extraction. Biomaterials associated with resorbable or non-resorbable membranes, when placed in the region of the socket, may contribute to avoid this unwanted reabsorption. Ob

3. In vivo Study of the Osteoregenerative Potential of Polymer Membranes Consisting of Chitosan and Carbon Nanotubes
Biomaterials with the hydroxyapatite and biopolymers such as chitosan derived of crustaceans are is an alternative for bone repair. Carbon nanotubes have been a focus of interest because they can ameliorate the biomechanical properties of biomaterials. The objective of this study was to evaluate these materials in the repair of cranial defects in rats. The a

4. Avaliação da terapia com dose sub-antimicrobiana de doxiciclina como um modulador da resposta imuno-inflamatória do hospedeiro em modelo de doença periodontal e os efeitos dessa terapia sobre a susceptibilidade da Porphyromonas gingivalis / Evaluation of therapy with sub-antimicrobial dose of doxycycline as a modulator of the immune-inflammatory response of the host model of periodontal disease and the effects of this therapy on the susceptibility of Porphyromonas gingivalis
Periodontite é a doença multifatorial que envolvem interações entre algumas espécies bacterianas, como Porphyromonas gingivalis W83 e células do hospedeiro. Levando a uma resposta imuno-inflamatória que causa a destruição do tecido ósseo e gengival Neste contexto, fármacos com a habilidade de modular este processo imuno-inflamatório podem auxilia

5. Preliminary viability studies of fibroblastic cells cultured on microcrystalline and nanocrystalline diamonds produced by chemical vapour deposition method
Implant materials used in orthopedics surgery have demonstrated some disadvantages, such as metallic corrosion processes, generation of wear particles, inflammation reactions and bone reabsorption in the implant region. The diamond produced through hot-filament chemical vapour deposition method is a new potential biomedical material due to its chemical inert

6. Respostas ao treinamento resistido em relação à densidade mineral óssea e marcadores ósseos no polimorfismo foki do gene receptor de vitamina D em idosas
The aim of this study was to determine the influence of the vitamin D receptor (VDR) gene FokI genotype on both bone mineral density (BMD) and bone markers (BM) response to resistive training (TR) in Brazilian postmenopausal women. Methods 235 postmenopausal women (66.6 5.5 years) were studied before and after six months of RT. A total of 44 subjects complet

7. Aspectos celulares, teciduais e moleculares da osteogênese ectópica e ortotópica induzida pela matriz alogênica óssea e dentinária / Cellular, tissue and molecular aspects of the ectopic and orthotopic osteogenese induced by bone and dentine allogenic matrix
The aim of the present work was to correlate the cellular and tissue events with the expression of VEGF, BMP-7, RANKL and OPG during ectopic and orthotopic osteogenesis, induced by bone and dentin allogeneic matrix. Allogenic matrices obtained from femur and incisor of rats and demineralized in 0.6 N HCl were implanted into a intramuscular pocket and a 8mm-d

8. Efeito da pinealectomia na remodelação do osso alveolar de ratos submetidos à movimentação ortodôntica
Melatonin participates in a wide variety of physiological functions, including sleep induction, gastrointestinal activity, immune defense response, cardiovascular function, renal function and reproduction. This hormone also has effect in bone physiology, modulating osteoblasts and osteoclast activity. The aim of this study was to evaluate the involvement of

9. PINO ÓSSEO HOMÓLOGO CONSERVADO EM GLICERINA A 98% NA OSTEOSSÍNTESE UMERAL DE POMBOS DOMÉSTICOS (Columba livia) / HOMOLOGOUS BONE PIN CONSERVED IN GLYCERIN AT 98% IN HUMERUS OSTEOSYNTESIS OF DOMESTIC PIGEONS. (Columba livia)
The objective of the present study was to evaluate the use of a homologous bone pin, conserved in 98 % glycerin associated to hemicerclage with 910 polyglactin in transverse humerus osteosynthesis in domestic pigeons (Columba livia). The distal part of the tibialtarsus, conserved with bone marrow, was used as a bone pin. Twenty non-sexed healthy adult domest

10. EFEITO DO LASER DE BAIXA POTÊNCIA NO PADRÃO DA MOVIMENTAÇÃO DENTÁRIA INDUZIDA E NOS TECIDOS CO-RELACIONADOS
Stimulating agents of orthodontic movements have been studied to decrease the treatment time and to reduce the tissues damage. This research represents a histologic analysis of the pulpar, periodontal and bone tissues, and a macroscopic analysis after an induced dental movement on the upper molars of rats, radiated or not with low-level laser. For the laser

11. Use of radiograph optical densitometry to monitor bone quality in broiler breeders
This study was carried out at Faculdade de Medicina Veterinária e Zootecnia, Universidade Estadual Paulista, Botucatu, SP, Brazil, and evaluated bone quality in broiler breeders. Twenty-three families of Ross broiler breeders were housed in 5.0-m² pens. The families were comprised of 13 females and one male at the onset of the experimental period. The mean

12. Efeito da radiação gama no processo de reparação ossea em ratas com deficiencia de estrogenio
As osteoporosis is a condition that causes bone fragility and ionization radiation makes the repair process difficult, the experiment was carried out to check the effect of the association of estrogen deficiency and ionization radiation on the bone repair process. The 4 experimental groups of female Wistar rats were subjected to the following conditions: con
