Diagnostico precoce na displasia cementaria periapical: relato de caso com 7 an...
Reis,Júlia Vianna Néri Andrade; Nogueira,Fernanda Bonifácio de Andrade; Souza,Daniel Adrian Silva; Santos,Jean Nunes dos; Ramalho,Luciana Maria PedreiraResumo A displasia cementária periapical é um distúrbio de formação e remodelação do tecido ósseo que durante o seu desenvolvimento sofreu alteração na diferenciação celular, resultando num tecido malformado. Apresenta-se predominantemente em pessoas do gênero feminino, etnia negra e na faixa etária dos 40 anos. Pode ser confundida com as lesões periapicais inflamatórias de origem endodôntica devido à semelhanç...
Actinomycosis is not Frequent in the Periapex But is a Persistent Lesion
Esteves,Lucas Senhorinho; Henriques,Águida Cristina Gomes; Silva,Carolina Ávila Varginha de Moraes e; Cangussu,Maria Cristina TeixeiraAbstract Periapical actinomycosis caused by a gram-positive anaerobic pathogen characterizes a typical extra-radicular infection. This study determined the frequency and correlated the content of bacteria colonies with the of periapical actinomycosis size. The study comprised a total of 218 periapical lesions (PL) (cysts, granulomas or abscess). The specimens embedded in paraffin were sliced into 4-µm sections ...
Histochemical and immunohistochemical differences between solitary oral fibroma...
Henriques,Águida Cristina Gomes; Freitas,Roseana de Almeida; Pires,Bruno Cunha; Gurgel,Clarissa Araújo; Santos,Jean Nunes dosAbstract: Background: The morphological similarities between fibrous papules of the face and multiple sporadic oral fibromas were mentioned long ago and a relationship between them has been reported in the literature. Objective: The aim of this study was to evaluate the participation of mast cells, elastin and collagen in a series of oral fibromas and fibrous papules of the face in order to better understand th...
Why segment the maxilla between laterals and canines?
Esteves,Lucas Senhorinho; Santos,Jean Nunes dos; Sullivan,Steven M.; Martins,Luana Maria Rosário; Ávila,CarolinaIntroduction: Maxillary surgery on a bone segment enables movement in the sagittal and vertical planes. When performed on multiple segments, it further provides movement in the transverse plane. Typical sites for interdental osteotomies are between laterals and canines, premolars and canines, or between incisors. Additionally, osteotomies can be bilateral, unilateral or asymmetric. The ability to control interc...
Repair of Surgical Bone Defects Grafted with Hydroxylapatite + β-TCP and Irradi...
Soares,Luiz Guilherme P.; Marques,Aparecida Maria C.; Guarda,Milena G.; Aciole,Jouber Mateus S.; Pinheiro,Antonio Luiz B.; Santos,Jean Nunes dosThe treatment of bone loss due to different etiologic factors is difficult and many techniques aim to improve the repair, including a wide range of biomaterials and recently, photobioengineering. This work aimed to assess by histological analysis the repair of bone defects grafted with biphasic synthetic micro-granular HA + β-TCP associated with LED phototherapy. Forty rats were divided into 4 groups (Clot, LED...
Tumor-Infiltrating Macrophage and Microvessel Density in Oral Squamous Cell Car...
Boas,Deise Souza Vilas; Takiya,Christina Maeda; Gurgel,Clarissa Araujo Silva; Cabral,Marcia Grillo; Santos,Jean Nunes dosTumor-associated macrophages (TAM) are the main cellular component in stroma of many tumors and participate in tumor angiogenesis. The aim of present study was to compare the microvascular density (MVD) and infiltrating macrophage density (IMD) in oral squamous cell carcinomas (OSCCs) with different histological grades. A histomorphometric analysis was performed after immunohistochemistry using antibodies such ...
Oral findings in patients with mucolipidosis type III
Cavalcante,Weber Céo; Santos,Luciano Cincurá Silva; Santos,Josiane Nascimento dos; Vasconcellos,Sara Juliana de Abreu de; Azevedo,Roberto Almeida deMucolipidosis type III is a rare, autosomal recessive disorder, which is part of a group of storage diseases as a result of inborn error of lysosomal enzyme metabolism. It is characterized by the gradual onset of signs and symptoms affecting the physical and mental development as well as visual changes, heart, skeletal and joint. Although oral findings associated with mucolipidosis type II have been extensively...
Histopathological study of radicular cysts diagnosed in a Brazilian population
Santos,Luciano Cincurá Silva; Vilas Bôas,Deise Souza; Oliveira,Gabriel Queiroz Vasconcelos; Ramos,Eduardo Antônio GonçalvesThe aim of this study was to investigate the histopathological features of radicular cysts (RCs) diagnosed in a Brazilian population. Seventy-three cases of RCs, from a total of 1480 biopsies diagnosed between 2001 and 2008 at the Laboratory of Oral Surgical Pathology of the Dental School of the Federal University of Bahia were investigated regarding their histopathological features. Morphological results showe...
Removal of oral lichen planus by CO2 laser
Magalhaes-Junior,Edival Barreto de; Aciole,Gilberth Tadeu; Santos,Nicole Ribeiro Silva; Santos,Jean Nunes dos; Pinheiro,Antonio Luiz BarbosaThe aim of this case report is to present a histologically diagnosed oral lichen planus excised by the CO2 laser. Oral lichen planus is a chronic inflammatory mucocutaneous disease of unknown etiology. Different treatments have been used to manage this condition. A 46 year-old female was referred to the Laser Clinic of the Dental School of the Federal University of Bahia to excise a lesion characterized by whit...
Surgical treatment of oral lymphangiomas with CO2 laser: report of two uncommon...
Aciole,Gilberth Tadeu dos Santos; Aciole,Jouber Mateus dos Santos; Soares,Luiz Guilherme Pinheiro; Santos,Nicole Ribeiro Silva; Santos,Jean Nunes dosThis paper reports the treatment of oral lymphangiomas with carbon dioxide CO2 Laser. Lymphangiomas are rare congenital lymphatic malformations. These lesions are most frequently diagnosed during childhood, are most commonly located in the head and neck region, and are extremely rare in the oral cavity. Oral lymphangiomas are of complex treatment due to the difficulty in performing a complete excision. CO2 lase...
