Clinicopathological and demographic characteristics of ameloblastomas in a population from Bahia, Brazil =Características clinicopatológicas e demográficas de ameloblastomas em uma popula o da Bahia, Brasil
Santos, Jean Nunes dos et al.
Revista Odonto Ciência , 2010,
Abstract: Objetivo: O presente estudo se prop e a revisar uma série de casos de ameloblastomas, realizando-se um estudo demográfico e comparando com trabalhos prévios. Métodos: Após aprova o pelo comitê de ética, 70 casos de ameloblastomas foram recuperados dos arquivos do servi o de Patologia Cirúrgica da Faculdade de Odontologia da Universidade Federal da Bahia e analisados quanto as suas características clínicas e histopatológicas. Resultados: Dos 70 casos, 35 (50%) acometeram o sexo masculino e 35 (50%) o sexo feminino. Os adultos jovens foram os mais afetados pelos tumores. A mandíbula foi o sítio preferencial, correspondendo a 56 casos (80%) do total dos tumores analisados. O principal subtipo histológico encontrado foi o ameloblastoma unicístico que acorreu em 35 casos. A maioria dos tumores [n=57 (81,4%)] foram tratados cirurgicamente de forma radical. Conclus o: O perfil clínico- epidemiológico dos pacientes do presente estudo é similar ao de outras popula es. Em adi o, o ameloblastoma unicístico é o subtipo histológico mais comum em nossa popula o.

Abstract: this 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 laser is the most often used laser in the oral cavity due to its affinity with water and high absorption by the oral mucosa. several benefits of the use of co2 laser have been reported for surgical oral procedures. the cases reported herein were biopsy-proven lymphangiomas of the oral cavity. the surgical procedures were carried out under local anesthesia and a focused co2 laser beam (l10.600 nm, f ~2 mm, cw/rsp) was used. at the end of the surgery, the laser beam was used on a defocused mode to promote better hemostasis. neither sutures nor dressings were used after surgery. no medication and only mouthwashes were prescribed to all patients on the postoperative period. there were no postsurgical complaints from the patients and no relapses of the conditions were observed after follow-up periods of 12 and 18 months. the use of co2 laser was practical, easy to carry out and effective on the treatment of oral lymphangiomas, with no lesion recurrence.

Ciência & Desenvolvimento , 2010,
Abstract: O objetivo desta pesquisa foi analisar as altera es cronológicas do reparo de queimaduras de terceiro grau em dorso de ratos provocadas pelo diabetes melitus. Para tanto, 30 ratos albinus Wistar foram distribuídos em dois grupos, (n=15). Em um dos grupos foi induzido diabetes mellitus utilizando a estreptozotocina (60mg/Kg). A queimadura foi criada no dorso dos animais, que ent o foram alocados em subgrupos de 3, 5, 7, 14 e 21 dias. Os espécimes removidos foram processados, corados com HE e Picrosírius e analisados sob microscopia de luz. Os resultados mostraram nos animais diabéticos, altera es no início da forma o do tecido de granula o, aumento de células da inflama o aguda até o sétimo dia, aumento da síntese de tecido de granula o e seus componentes no quinto e sétimo dia e diminui o dos mesmos a partir do décimo quarto dia e ausência de forma o de crosta quando comparados com os animais do grupo controle. P de-se Concluir que o diabetes melitus altera os períodos de forma o do tecido de granula o, além de exacerbar e prolongar o tempo da inflama o aguda no processo de reparo de queimaduras de terceiro grau em dorso de ratos Wistar.

Abstract: cystadenoma of salivary glands is an uncommon benign neoplasm that presents intraluminal papillary projections. the authors describe one case of cystadenoma located in the buccal mucosa and highlight its histomorphological features and differential diagnosis.
Caracteriza??o imuno-histoquímica de les?o híbrida de ameloblastoma desmoplásico e convencional
Santos, Jean Nunes dos;De Souza, Veronica Ferreira;Azevêdo, Roberto Almeida;Sarmento, Viviane Almeida;Souza, Lélia Batista;
Revista Brasileira de Otorrinolaringologia , 2006, DOI: 10.1590/S0034-72992006000500020
Abstract: ameloblastoma is a benign epithelial odontogenic tumor and is the most commonly encountered odontogenic tumor in the jaws. histologically, ameloblastomas occur in different patterns, including plexiform pattern and follicular pattern. "hybrid " lesion of ameloblastoma is a tumor variant in which histologically, areas of follicular or plexiform ameloblastoma coexist with characteristic areas of ameloblastoma exhibiting pronounced stromal desmoplasia (desmoplastic ameloblastoma). the purpose of this article is to present a case of "hybrid" lesion of desmoplastic ameloblastoma (ad) and conventional, and investigate extracellular matrix proteins such as tenascin, fibronectin, and type i collagen.

RGO : Revista Gaúcha de Odontologia , 2008,
Abstract: Objective: In this study, the aim was to analyze the histologic alterations in thirty dental pulps and correlate them with the clinical findings to verify agreement between the clinical and histopathologic diagnosis and contribute to knowledge about endodontic diagnosis. Methods: Using the methodology of Oliveira4, the pulpal conditions were clinically classified as normal, reversible pulpitis, pulpitis at the stage of transition, irreversible pulpitis and necrosis. Results: Lack of correlation was observed between the clinical and histopathologic diagnoses in the cases classified as reversible and at the stage of transition, which histologically consisted of irreversible lesions or degenerative alterations. All the cases clinically classified as irreversible corresponded to the histologic diagnoses. Conclusion: It was concluded that the correlation between clinical and histopathologic diagnosis of dental pulp was shown to be controversial, even though the semiotechnique used had been imperative for guidance about the irreversibility of pulpal lesion.

Magalhaes-Junior, Edival Barreto de;Aciole, Gilberth Tadeu;Santos, Nicole Ribeiro Silva;Santos, Jean Nunes dos;Pinheiro, Antonio Luiz Barbosa;
Brazilian Dental Journal , 2011, DOI: 10.1590/S0103-64402011000600014
Abstract: the 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 white patches on the oral mucosa, which was causing pain and burning sensation and had not respond to treatment with triamcinolone and corticosteroids for 3 months. co2 laser was used to remove the lesion and the conclusive histopathological diagnosis was oral lichen planus. the patient was followed up over 1year with no signs of lesion recurrence. the use of the co2 laser was found to be useful and effective to treat lichen planus.

Abstract: the 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 showed that exocytosis (n=50), spongiosis (n=40), acanthosis (n=28), atrophic epithelium (n=27) and apoptotic bodies (n=21) were the most common findings. other morphological findings included: foamy macrophages (n=10), russell’s bodies (n=7), cholesterol crystals (n=7) and glandular-like odontogenic epithelial rests (n=1). evidence of exogenous material was seen in 16 samples. it was concluded that the clinical and histopathological findings observed in brazilian patients were comparable with those described for other populations.
