The aim of this study was to evaluate the calcium dosage of the newly formed bone, in critical bone defects created on the calvarial tissue and filled by different substances, in male Wistar rats. A cylindrical critical bone defect (6x2mm) was created in the posterior portion, left side, on the calvarial bone in nine animals and filled with: animals' coagulum, monoolein gel, poloxamer gel, monoolein gel + 1µg rhBMP-2, monoolein gel + 3µg rhBMP-2, monoolein gel + 7µg rhBMP-2, poloxamer gel + 1µg rhBMP-2, poloxamer gel + 3µg rhBMP-2, poloxamer gel + 7µg rhBMP-2. The results of this study showed a positive correlation between the calcium dosage analysis and the newly formed bone |

The aim of this article is to show the clinical and histochemical alterations of the first periodontal ligament, on the right side, after upper molars teeth extraction on the left side in gerbils. After two months, the periodontal ligaments were removed and processed for histochemical analysis. The data showed that TRAP reaction was able to evidence the osteoclastic activity in the hyperfunction hemimandible, right side, explaining the functional changes in the periodontal ligament after teeth extraction, and a little gingival recession and radicular exposure of teeth without function was observed at inferior molars of the left side |

The aim of this study was to present a possible carrier for MTA, monoolein gel, with the objective to maintain this material in the place that was inserted and verify if this procedure is able to optimize its action. The data were evaluated by histomorphometric method and submitted to statistical analysis. The histological responses observed in this study indicate that the MTA is a reliable material and should be considered effective in bone periapical defects and the monoolein gel was capable to maintain the MTA in situ |

Considering the biomechanical aspects, many facts need to be understood on the mandible, to know which effects unilateral occlusal changes may cause on the stomatognathic system. The aim of this study was to analyze the malocclusion by unilateral teeth extraction on the mandible morphology in gerbil. We used 10 gerbils Meriones unguiculatus, young male, weighing around 50-60g, divided into two groups (n=5), an experimental group and control, which evaluated the two hemi-mandibles, with a total of 20 samples which were measured by digital pachymeter. The measures were taken: (1) length and (2) width of the mandible condyle and (3) body height in the region of mandibular 1st molar. Data from these measurements were analyzed using ANOVA and Mann-Whitney test.... |

The aim of this study was to correlate the morphodigital characteristics of the trabecular mandibular bone, in this way, it is possible to observe osteoporosis clue in patients of both sex, using panoramic radiograph for analysis. The results of this study showed statistical difference between men and women considering the bone trabecular measures (p<0.05), but it was not found statistical difference between the sides in each analyzed group (p>0.05). Male group presented a more strongly trabecular and complex bone than the female group, this finding is important index to osteoporotic risk, being possible to affirm that the male bone is less probable to suffer a osteoporotic fracture |

The purpose of this study was to evaluate the newly formed bone, comparing two different carriers for rhBMP-2, using the decortication and nondecorticatication surgical technique in Wistar rat mandibles, evaluated by radiographic densitometry method. It was used fifty six animals according to specific treatment, which were sacrificed after 3 and 6 weeks after this. It was concluded that the decortication surgical technique was able to optimize the osteoinduction properties of the rhBMP-2, independently of the material carrier used and the period of time, according to radiographic densitometry technique. |

The skeleton has several important functions, such as structural functions that provide mobility, support, and protection for the body. It also has an important function as a reservoir for calcium and phosphorus. The aim of this article is to show the principal hormones that are involved with the bone healing process. In this article, it will be pointed the mineral homeostatic mechanisms in the skeleton, controlled by the calcium-regulating hormones: parathyroid hormone (PTH) that maintains the normal extracellular calcium levels by enhancing osteoclastic bone resorption and liberating calcium from the adult skeleton; estrogen, considering that both osteoblasts and osteoclasts express estrogen receptors, it is reasonable to assume that the effects of... |

The present work aimed to preserve anatomical specimens to improve the quality of education, prepare supporting materials, and present lectures on the anatomy of the nervous system for public school students. Anatomical specimens related to the nervous system were photographed and named, and acrylic containers filled with formaldehyde were made for the accommodation of these specimens. After research on the subject a handbook and a banner were prepared, enriching the collections of the museum along with the anatomical specimens, in addition to the lecture and video available on "iptv.usp.br ". Meetings between the students, the teachers involved, and the members of the Secretariat of Education of Ribeirao Preto defined schools, dates, times, and duration... |
