Estudo da estabilidade da cirurgia do tipo sagital da mandíbula com vista a correção de deformidades faciais

This research evaluated the surgical stabilily in patients with mandibular prognathism and retrognathism in which was used sagital split technic to correct those detormities. Twelve patients were selected from the clinic of only one experienced surgeon. Six patients presenter a Class III 6 a Class II molar relationship. A comparative cefalometric analysis using linear and angular measurements was performed of pre-surgery, imediate pós-surgery and 1 year follow-up. The following conclusions were obtained. 1 The Dal Pont sagital split technic modified by Epker to correct mandibular prognathisn and retroghnatism is a stable technic and must be indicated to correct those deformities. 2 Small relapses are easily corrected by the post-surgical orthodontic treatment. 3 A small over correction is advised in cases of large mandibular advancements or set bascks. 4 In those cases which a large amount of mandibular retrusion on advancement need to be performed, a combination of maxillary and mandibular surgery should be used. Rigid fixation technic is also indicated in those cases

Histologia e histomorfometria do retículo de bovino no período pré-natal

The development of the stomach of ruminants requires further studies because it is a complex process. Therefore, was analyzed the histology and histomorphometry of reticulum at each gestation period. Samples of Nelore fetuses (Bos taurus indicus) was divided in 5 groups: 1 - fetuses at 9 to 15 weeks (8 to 21cm) of gestation, 2 - fetuses at 16 to 22 weeks (23 to 37cm) 3 - fetuses at 23 to 29 weeks (40 to 58cm), 4 - fetuses at 30 to 36 weeks (61 to 77cm) and 5 - fetuses at 37-43 weeks (79 to 88cm). The histological sections were stained with hematoxylin and eosin and Mallory's trichrome and examined by light microscopy. In group 1, the fetuses with 11 cm, showed mucosal projections that eventually become primary crests, lamina propria and submucosa are fused and external and internal muscular and similar. At 16.5 inches, the primary crests had lamina propria and at 18.5 cm, appeared connections between the ridges. In group 2, at 31 cm started epithelial involvement around the crests. In group 3, the fetuses of 42 cm revealed the first secondary papillae and muscular mucosa in the upper portion of the primary crests. Thereafter, it was increased epithelial due to its positioning around the crests, thickening of the lamina propriasubmucosa, muscular layer, especially the internal muscular and serosa. It was concluded that the most visible changes occur in fetuses belonging to the first 3 groups, measurements for the epithelium, muscle layer and total wall were increasing and the other analyzed layers showed variations during fetal development.

Detecção de Histophilus somni (Haemophilus somnus) no sêmen bovino mediante reação em cadeia pela polimerase (PCR)

The present study evaluated the use of PCR for Histophilus somni detection in bovine semen. Semen samples were experimentally infected with H. somni at dilutions ranging from 107 to 101 bacteria/mL and subjected to DNA extraction by the phenol/chloroform method, followed by PCR amplification. The amplification products were analyzed by electrophoresis in 8% acrylamide gel. The oligonucleotide primers used yielded an amplification fragment of 400 base pairs from the bacterial DNA. Positive amplification was obtained even for the 101 bacteria/mL dilution. PCR proved to be an efficient method for the detection of H. somni. The results obtained in this study have brought relevant information for the diagnosis of H. somni, justifying the need for the diagnosis of this bacterium in bulls, especially in semen samples that should be free of contamination. The PCR method has shown to be a useful tool for the quality control of semen produced in artificial insemination centers.

Carcinoma de células escamosas em assoalho vaginal de um bovino nelore associado a metástase em pulmão: relato de caso

The squamous cell carcinoma (SCC) is a neoplasm that affect pets and production animals and it’s very common in tropical countries like Brazil; develops in sparsely pigmented, stratified squamous epithelium and in mucosal surfaces exposed Ultraviolet action. The SCC is quite infiltrative but rarely causes metastases. Its occurrence in the female reproductive tract is recognized in the literature on cattle breeds from Europe. This case was a female bovine, Nelore, adult, who was referred to the "Hospital Veterinário Luiz Quintiliano de Oliveira" with dark brown fluid leakage and putrid odor, associated with ulcerative growth of the vagina. Because the extent of injury, the animal was euthanized and taken to the necropsy, which was observed on board structure, ulcerated and pus in the vaginal floor, infiltrated into the pelvic cavity to the serosa of the uterine body. The microscopic findings were detected neoplastic proliferation of epithelial cells in the floor and vaginal metastases in the lung parenchyma, and classified the primary tumor and metastasis as squamous cell carcinoma moderately differentiated.

Visão contemporânea do uso de implantes de conexão interna tipo cone morse

The Morse Taper implant system, developed from its introduction in engineering, has become increasingly effective for use in dentistry. However, other systems, main external hexagon type, have been used more frequently today. Current studies have been reported the positive features of the Morse taper system and even emphasized as ideal within the systems used in implantology. Unfortunately, some professional duty by not knowing this system, or even prefer hexagon type system by decreased cost of components, have refused to use it. Thus, this study was aimed to perform a brief review of the Morse taper system, emphasizing its main points of interest in dentistry, in an attempt to familiarize the professionals to at least learn more about this system that has the prospect to become the leading system implants used in dentistry in the coming years. It is concluded that this system of dental implants is favorable showing predictability and success.

Implantes tipo plataforma modificada: revisión de literatura

The purpose of this revision was to explore the concept of Platform Switching in implantology and its acting in the clinical practice. The concept of platform switching will be considered together with a revision of pertinent literature, with the purpose of providing guidelines based on scientific evidences. The following databases were used: Pubmed, Library Cochrane and ISI in the last 17 years. The inclusion approaches were: clinical articles, laboratorials and of revision on the topic, in English language. 41 articles were selected, using the describers "platform switching dental implants", "platform shifting and dental implants", "expanded platform dental implant". In accordance with this revision, implant them platform switching they present a rate of more favorable bony remodeling that you implant them conventional. This fact seems to be resulting of a group of biological factors and mechanics. The concept of platform switching has important relevance in the aesthetic area.
