A porous material for bone ingrowth with adequate pore structure and appropriate mechanical properties has long been sought as the ideal bone-implant interface. This study aimed to assess in vivo influence of three types titanium implant on new ingrowth. The implants were produced by means a powder metallurgy technique different porosities sizes: Group 1 = 30 % 180 µm; 2 30% 300 3 40% µm;. Six rabbits received one each type right left tibiae sacrificed 8 weeks after surgery histological...
A panel of antibodies composed the cytokeratins (CKs), vimentin, and actin was applied to 114 minor salivary gland tumors evaluate its diagnostic value. The results revealed that luminal cells intercalated duct-like structures, such as those seen in pleomorphic adenoma, basal cell adenoid cystic carcinoma, epithelial-myoepithelial expressed CKs 7, 8, 14, 19. outer these structures exhibited vimentin or plus muscle-specific actin, but rarely CK14, which is particularly tubular type seldom...
Titanium (Ti) and Ti-6 Aluminium-4 Vanadium alloys are the most common materials in implants composition but β type promising biomaterials because they present better mechanical properties. Besides of biomaterial, many factors influence performance biomaterial. For example, porous surface may modify functional cellular response accelerate osseointegration. This paper presents vitro vivo evaluations powder metallurgy-processed samples composed by different titanium pure Ti, aiming to show...
Porous titanium scaffolds are promising materials for biomedical applications such as prosthetic anchors, fillers and bone reconstruction. This study evaluated the bone/titanium interface of with interconnected pores prepared by powder metallurgy, using scanning electron microscopy (SEM) energy dispersive spectroscopy (EDS). dense samples were implanted in tibia rabbits, which subsequently killed 1, 4, 8 weeks after surgery. Initial neoformation was observed one week implantation. Bone...
The potential f or malignant transformation of oral lichen planus is still controversial. expression proteins related to cell proliferation and apoptosis in epithelial dysplasia was analyzed evaluate the true for this disease. Twenty-four cases each lesion were subjected streptoavidin-biotin technique identifying immunohistochemical PCNA, p53, bax, bcl-2 proteins. Of 24 planus, 14 (58.33%) positive 10 (41.67%) 4 (16.67%) 12 (50%) whereas dysplasia, 20 (83.33%) 6 (25%) bcl-2, bax. Chi-squared...
Syphilis is a sexually transmitted infectious disease caused by Treponema pallidum. This study reports 3 cases of syphilis and highlights the importance identifying oral lesions for its final diagnosis. Case 1: 48-year-old male patient presented with bleeding ulcer in lower lip. Overall clinical examination revealed patchy alopecia skin target lesions. 2: 61-year-old white spots on lateral tongue nodules dorsum tongue. showed erythematous abdomen, forearm, palms hand, soles feet. 3:...
Objective: The aim of this study was to carry out an in vivo assessment bone ingrowth two different types porous titanium -the first being completely porous, and the second with a surface dense nucleus, manufactured by powder metallurgy-and evaluate their mechanical properties.Study design: Ten scaffolds from each group were submitted metallographic analysis compression tests.Next, type inserted into 14 rabbits, which sacrificed 8 weeks after surgery.The samples for histological...
The purpose of this study was to analyze the bone repair around commercially pure titanium implants with rough and porous surface, fabricated using powder metallurgy technique, after their insertion in tibiae rabbits. Seven male rabbits were used. Each animal received 3 porous-surface left tibia rough-surface right tibia. sacrificed 4 weeks surgery fragments containing submitted histological histomorphometric analyses evaluate new formation at implant-bone interface. Means (%) neoformation...
The purpose of this study was to evaluate the effects simvastatin on guided bone regeneration in mandibles ovariectomized rats, and observe their blood cholesterol levels. Seventy female rats were divided into two groups : control treated, both containing normal rats. A month after ovariectomy a defect created mandible, covered by polytetrafluoroethylene membrane. treated received orally for 15 or 30 days. sacrificed 15, 60 days surgery, at which time sample extracted level analysis mandible...
O presente trabalho teve como objetivo pesquisar a ocorrência de leishmaniose visceral em cães com sinais clínicos compatíveis, procedentes clínicas veterinárias das diferentes regiões do Estado Paraná e caso positivo verificar autoctonia dos mesmos.Dos animais suspeita clínica epidemiológica LV, foi coletada amostra sangue para realização hemograma, provas bioquímicas, sorologia, cultura parasito, PCR RAPD.Os portadores quadro clínico, febre, hiperqueratose, onicogrifose emagrecimento...
The main goal of this study was to histologically evaluate the healing surgically created defects on tibiae adult male rats after implantation two types bioactive glass. Sixteen Wistar (body weight 300g) were divided into groups: PerioGlas (PG) (n=8) and BioGran (BG) (n=8). Unicortical bone with 3-mm diameter performed in both animals filled glass particles. then sacrificed at 7, 14, 30 60 days, tissues prepared for histological processing, sectioning, staining hematoxylin eosin, as well...
Abstract Introduction Necrotizing sialometaplasia is a benign, self-limiting and rare inflammatory disease which, on clinical histological examination, mimics malignant neoplasms. Case report We the case of healthy 25-year-old Caucasian woman with three-week history painless lump her hard palate. Oral examination revealed nodule consisting two lobules right side that measured 2.5 cm. Her mucosa was normal in color fluctuant area detected posterior region upon palpation. Our patient submitted...
Abstract Introduction Granular cell tumor is an uncommon neoplasm that can occur in any part of the body, including orofacial region. The usually benign, but there are reports cases which shows a locally aggressive behavior, malignancy, and distant metastases. most widely accepted hypothesis granular arises from altered metabolism Schwann cells. typically asymptomatic appears as nodule does not exceed 3 cm. Case presentation In case 1, 26-year-old Caucasian man was seen at Oral Medicine...
