Pyogenic granuloma on the upper lip: an unusual location

Pyogenic granuloma (PG) is a benign non-neoplastic mucocutaneous lesion. It is a reactional response to constant minor trauma and might be related to hormonal changes. In the mouth, PG is manifested as a sessile or pedunculated, resilient, erythematous, exophytic and painful papule or nodule with a smooth or lobulated surface that bleeds easily. PG preferentially affects the gingiva, but may also occur on the lips, tongue, oral mucosa and palate. The most common treatment is surgical excision. This paper describes a mucocutaneous PG on the upper lip, analyzing the clinical characteristics and discussing the features that distinguish this lesion from other similar oral mucosa lesions. The diagnosis of oral lesions is complex and leads the dentist to consider distinct lesions with different diagnostic methods. This case report with a 4 year-follow-up calls the attention to the uncommon mucocutaneous labial location of PG and to the fact that surgical excision is the safest method for diagnosis and treatment of PG of the lip, even when involving the mucosa and ski

Bilateral jaws involvement of Burkitt?s lymphoma in a pediatric patient

CBCT location of the fusion between the buccal and lingual cortical in the mandibular ramus : importance to sagittal split osteotomy

Mandibular Sagittal Split Osteotomy (MSSO) is a popular technique in orthognathic surgery used both to advance and to retreat the mandible. However, MSSO may incur in important complications, such as bad splits and sensorineural injuries. Knowing the location of the fusion between the buccal and lingual cortical (FBLC) in the mandibular ramus and the bone thickness in the region where osteotomies will be performed is determinant in MSSO planning to avoid complications. The aim of this study was to document and evaluate possible differences between sexes regarding the location of the FBLC in relation to the superior cortical of mandibular foramen (MF) and bone thickness in the region of interest for MSSO in a Brazilian population. Eighty five cone-beam Computed Tomography (CBCT) scans were used to perform linear measurements to determine the location of the FBLC. Bone thickness from the mandibular canal (MC) to the cortical external surfaces and the diameter of the MC were measured at three different points: mandibular ramus (A), mandibular angle (B) and mesial of the second molar (C). The FBLC was located at a mean distance of 8.3 mm from the superior cortical of the MF in males and 8.1 mm in females. There was no difference between males and females regarding the mean bone thickness from the MC to the buccal external surface at all the points investigated (p >>0.05). Bone thickness from the lingual external surface to the MC was bigger among females than males in regions B and C (p<0.05). The diameter of the MC was bigger among males in regions B and C. Sexual dimorphism regarding mandibular bone thickness but not regarding the location of FBLC was present. This fundamental knowledge may assist to the panning of MSSO

Integração Ensino-Serviço no acolhimento ao calouro do Campus USP-Bauru.

The reception of new students in college is the focus of great concern today. This paper aims to report the activity "Health is what matters" from New Students Reception’s Week 2014 with a view to disseminate an activity eminently about health promotion community accomplished from the concept of education-service integration in the host of new students of Dentistry and Speech Language and Hearing Sciences from the Campus USP at Bauru. A public square was structured by areas: education and prevention in dentistry, fisiology and speech language pathology and Audiology, supervised toothbrushing with fluoride toothpaste and prevention of oral cancer. This activity enabled the experience of the needs of the community Bauru, alowing students to reflect from the first week at university about the responsibilities that the healthcare professional has with society.A recepção ao calouro na universidade é foco de grande preocupação atualmente. Este trabalho tem o objetivo de relatar a atividade “Saúde é o que interessa” da Semana de Recepção de Calouros 2014, com vistas à divulgação de uma atividade eminentemente de promoção de saúde da comunidade, realizada a partir do conceito de integração ensino-serviço no acolhimento ao calouro de Odontologia e Fonoaudiologia do Campus USP-Bauru. Uma praça pública foi estruturada por áreas de atuação: educação e prevenção em odontologia e em fonoaudiologia e em fisiologia, escovação dentária com dentifrício fluoretado supervisionada e prevenção do câncer bucal. Esta atividade permitiu a vivência das necessidades da comunidade bauruense, fazendo com que os estudantes pudessem refletir desde a primeira semana na universidade sobre as responsabilidades que o profissional da área de saúde tem com a sociedade

Estudo das diferenças de calibre entre as arterias vertebrais esquerda e direita por angiografia cerebral

Orientador: Heloisa Amelia de Lima e CastroDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Odontologia de PiracicabaResumo: Estudaram-se 14 coelhos adultos da raça Norfolk inglesa, que foram submetidos à angiografia cerebral do território vértebro-basilar durante anestesia geral, com o objetivo de se comparar os calibres das artérias vertebrais. Dentre os 14 casos analisados, o calibre da artéria vertebral esquerda foi maior em 5 (36 %), o da direita foi maior em 3 (21 %) e os calibres foram considerados similares em 6 (43 %). Estes achados guardam analogia com os dados disponíveis sobre as diferenças de calibre entre as artérias vertebrais do homemAbstract: Fourtheen normal adult Norfolk English rabbits were submitted to angiographies of the vertebral arterial blood vessels, during geral anesthesia. The objective was to compare the diameter between the left and right vertebral arteries. Among the 14 analyzed cases, the left vertebral artery was bigger in 5 (36%), the right vertebral artery was bigger in 3 (21%) and the diameter was similar in 6 (43%). This data are similar to some disponible anatomical records of the human vertebral arterial territoryMestradoAnatomiaMestre em Biologia Buco-Denta

Radiological and histopathological evaluation of experimentally-induced periapical lesion in rats

OBJECTIVE: This study evaluated experimentally-induced periapical bone loss sites using digital radiographic and histopathologic parameters. MATERIAL AND METHODS: Twenty-seven Wistar rats were submitted to coronal opening of their mandibular right first molars. They were radiographed at 2, 15 and 30 days after the operative procedure by two digital radiographic storage phosphor plates (Digora®). The images were analyzed by creating a region of interest at the periapical region of each tooth (ImageJ) and registering the corresponding pixel values. After the sacrifice, the specimens were submitted to microscopic analysis in order to confirm the pulpal and periapical status of the tooth. RESULTS: There was significant statistically difference between the control and test sides in all the experimental periods regarding the pixel values (two-way ANOVA; p<0.05). CONCLUSIONS: The microscopic analysis proved that a periapical disease development occurred during the experimental periods with an evolution from pulpal necrosis to periapical bone resorption

Case-control study of oral disease indexes in individuals with head and neck cancer after antineoplastic therapy

<div><p>ABSTRACT Objective To evaluate the oral health of patients with head and neck cancer after antineoplastic treatment, and to compare them with patients with no history of cancer. Methods A total of 75 patients, divided into Study Group, composed of individuals after antineoplastic treatment (n=30), and Control Group, with individuals with no history of cancer (n=45), aged 37 to 79 years. The oral health status was evaluated through the index of decayed, missing or filled permanent teeth (DMFT), community periodontal index and evaluation of the use and need of prosthesis. All of these items were evaluated according to the criteria recommended by the World Health Organization. The statistical analysis was descriptive and used the Pearson’s χ2 test. Results The community periodontal index was higher in the Study Group when compared to the Control Group (p<0.0001). The need for an upper (p<0.001) and lower (p<0.0001) prostheses was higher in the Study Group. Also, the use of upper prosthesis was higher in the Study Group (p<0.002). The missing or filled permanent teeth index between the two groups (p>0.0506) and the use of lower prosthesis (p>0.214) did not present a relevant statistical difference. Conclusion Periodontal disease and edentulism are the most significant changes in individuals who received antineoplastic therapy for head and neck cancer as well as greater need for oral rehabilitation.</p></div
