1. Does traumatic occlusal forces lead to peri-implant bone loss? A systematic review
Abstract Observational studies have indicated that crestal bone level changes at implants are typically associated with clinical signs of inflammation, but still mechanical overload has been described as possible factor leading to hard–tissue deficiencies at implant sites without mucosal inflammation. The aim of this paper was systematically review the lit

2. Bone turnover markers in sheep and goat: A review of the scientific literature
ABSTRACT Bone turnover markers (BTMs) are product of bone cell activity and are generally divided in bone formation and bone resorption markers. The purpose of this review was to structure the available information on the use of BTMs in studies on small ruminants, especially for monitoring their variations related to diet, exercise, gestation and metabolic l

3. Effects of a Mikania laevigata extract on bone resorption and RANKL expression during experimental periodontitis in rats
OBJECTIVES: The Mikania laevigata extract (MLE) (popularly known in Brazil as "guaco") possesses anti-inflammatory properties. In the present study we tested the effects of MLE in a periodontitis experimental model in rats. We also investigated possible mechanisms underlying such effects. MATERIAL AND METHODS: Periodontal disease was induced by a ligature pl

4. Modulação do transporte de prótons em osteoclastos: efeitos da acidose e do fluxo de fluido extracelular. / Modulation of proton transport in osteoclasts. Effects of acidosis and extracellular fluid flow.
Metabolic acidosis can cause a loss of bone mineral and the mechanic stimulation can cause adaptative bone remodeling. The bone resorption characteristic of these bone changes aforementioned depends on the extracellular acidification by osteoclastmediated proton secretion. The H+ secretion by vacuolar H+-ATPase together with Clsecretion through a Cl-/H+ exch

5. Interação do alendronato e da vitamina K no metabolismo osteomineral de ratas ovariectomizadas
The bone is a specialized form of connective tissue that provides support for metabolic and biomechanical throughout the body. Thus, the bone is very dynamic, with constantly renewing itself. His integrity therefore depends on the balance between the processes of formation and resorption. The loss of this balance alters both the structure of organic matrix a

6. Relação da distância interimplantar e altura do ponto de contato na formação de papilas gengivais: estudo em cães / Influence of interimplantar distance and height from the point of contact in the formation of gingival papilae: a study in dogs
Os implantes dentais são considerados uma modalidade de tratamento bastante previsível para a reposição de dentes perdidos. Os implantes osseointegráveis principalmente quando colocados em regiões anteriores devem oferecer, além de excelente função, ótima estética, e fonética. Sendo que o critério para o sucesso envolve o estabelecimento do cont

7. Alveolar bone changes caused by low level laser therapy during induced orthodontic movement on rats. / Alterações teciduais decorrentes da fotobiomodulação laser no movimento dentário induzido em ratos.
The use of laser phototherapy is considered an enhancement factor for bone repair as it stimulates microcirculation as well as the cellular metabolism. Regarding this, the purpose of this research was to assess histologic changes after the use of laser phototerapy during induced mesial tooth movement with 40g/F of the upper left first molars of young adult m

8. Efeito da utilização de plasma rico em plaquetas na osteointegração dos enxertos ósseos homólogos criopreservados: estudo histomorfométrico em coelhos / Effects of platelet rich plasma in osteointegration of cryopreserved homologous bone grafts: histomorphometric study in rabbits
Bone loss, in some segments of the muscle-skeleton system, are of great concern in the fields of Orthopedics and Traumatology. There are several options of treatment by means of bone grafts and growth factors. In this study we evaluate the effect of platelet rich plasma (PRP) in the initial phase of osteointegration of cryopreserved (- 80 °C) homologous bon

9. Evaluation of insertional torque and axial pull-out strength of mini-implants for orthodontic anchorage / Avaliação do torque de inserção e da força de arrancamento axial de mini-implantes para ancoragem ortodôntica
Introduction: The objectives of this study were to evaluate insertional torque of miniimplants (MI) for orthodontic anchorage, to compare MI axial pull-out strength at 0 (T0), 15 (T15) and 60 (T60) days after insertion, to determine initial and final cortical bone thickness, and to analyze the correlations among these variables. Methods: Sixty 1.6 x 6.0 mm M

10. Histological and radiographical analysis of the repair of rabbit femur deffects filled with bovine bone organic cancellous matrix in blocks or cortical matrix in micro granules / Análises microscópica e radiográfica do reparo de defeitos confeccionados em fêmures de coelhos preenchidos com matriz óssea bovina medular em bloco ou cortical em microgrânulos
The aim of this work was to verify the osseous repair in non through-andthrough defects treated with blocks of lyophilized bovine bone organic matrix of cancellous origin or micro granules (0.25-1.0 mm) of lyophilized bovine bone organic matrix of cortical origin (both materials Gen-Ox®- Baumer SA- Brazil). An osseous defect, 6mm in diameter by 8mm in depth

11. Influencia das condições hormonais da prenhez sobre a doença periodontal experimental : estudo radiografico e histologico em ratos
The obj ecti ve of this experiment was to examine the influence of pregnancy effects on the experimental periodontitis of the first mandibular molar of female Rattus norvergicus albinus provoked by the presence of a silk ligature around the neck of the tooth, the pregnancy and both the two factors acting in conjunction. The silk ligature was placed at the gi

12. Effect of MALP-2, a Lipopeptide from Mycoplasma fermentans, on Bone Resorption In Vitro
Mycoplasmas may be associated with rheumatoid arthritis in various animal hosts. In humans, mycoplasma arthritis has been recorded in association with hypogammaglobulinemia. Mycoplasma fermentans is one mycoplasma species considered to be involved in causing arthritis. To clarify which mycoplasmal compounds contribute to the inflammatory, bone-destructive pr
