O presente estudo teve como objetivos avaliar a integração e a satisfação acadêmica em universitários e analisar sua relação, conforme o curso e a etapa de formação. Participaram 203 estudantes dos cursos de Psicologia (n=76) e Odontologia (n=127) de uma universidade particular, sendo a maioria mulheres (n=158). Foram aplicados um Questionário de Vivência Acadêmica (QVA-r) e uma Escala de Satisfação Acadêmica (ESEA). Os resultados mostraram que os estudantes apresentaram níveis de integração e de satisfação superior à média. Foram detectadas diferenças entre os cursos relativas às variáveis focalizadas e correlações entre as dimensões. É possível afirmar que a integração e a satisfação, apesar de compartilhar aspectos comuns, avaliam construtos diferentes, ambos importantes para a compreensão do fenômeno complexo e multideterminado da vida acadêmica.

Introduction: The development of squamous cell carcinoma of oral cavity (SCC) is a multifactorial process, where the cellular mutagenesis is determined by co-carcinogenetic agents like the human papillomavirus (HPV). Objective: the objective of this study is to identify the HPV in the SCC by means of polymerase chain reaction (PCR). Methods: twenty cases of SCC have been analyzed where the material used was extracted from specimens included in paraffin blocks of the Pathology Laboratory file of the São Vicente de Paulo Hospital of Passo Fundo/RS in the period of 2003 to 2007. They were all male cases and the 6 th decade of life was the most prevalent. The lower lip was the region that comprises most of the defects and the histological grade "well-differentiated" from the World Health Organization was predominant. It has been detected the presence of HPV's DNA in four of the 20 cases of the SCC (20%). Conclusions: it can be assured that, by the fact of the HPV has been identified in a considerable percentage of cases of SCC, it can have influence on the genesis of the referred malignant neoplasia. So, more studies are necessary to define what is the possible role of HPV in the oral carcinogenesis.

BackgroundTo exam the biochemical, obstetric management and pregnancy outcome in women with intrahepatic cholestasis of pregnancy (ICP) and treatment with ursodeoxycholic acid (UDCA).MethodsPregnancy outcome in patients with ICP (N = 307) was studied and patients treated with UDCA (N = 208) vs. no UDCA were compared. The data of the antenatal visits, deliveries and neonatal outcome of 307 pregnancies with ICP was collected from the hospital computerized delivery room log book. UDCA was used in 208 pregnancies. The diagnosis was made by maternal pruritus and elevation of total fasting bile acid (BA) (>6 μmol/l) and elevation of serum alanine aminotransferases (ALT) (>45 U/l). Maternal and neonatal data was analysed and data of the patients who used UDCA during pregnancy was analysed separately and compared with the data from patients without medication.ResultsUDCA was well tolerated. Mothers receiving UDCA had ICP diagnosed five weeks earlier than mothers without medication. At the diagnosis, levels of total BA and ALT were higher in the group using UDCA compared to the group without medication. Most deliveries were induced and perinatal outcome was good. Apgar scores at 5 min were significantly lower in UDCA group (p < 0.05), but fetal umbilical artery pH values were similar in both groups (p > 0.05). There were 30 patients with total BA > 40 μmol/l at diagnosis, 24 with UDCA and 6 without medication and those deliveries were induced soon after diagnosis. The preterm labour was also more common in these patents (p < 0.05). Women with preterm babies had significantly early onset pruritus and ICP was diagnosed earlier. Serum ALT and total BA levels were significantly higher in those pregnancies at diagnosis and also at first control.ConclusionsPreterm labour was associated in severe ICP (total BA > 40 μmol/l), ALT levels were also significantly higher and ICP was diagnosed earlier (p < 0.05). Apgar scores were lower in preterm babies (p < 0.05), but umbilical artery pHvalues were not significantly lower. UDCA was well tolerated by pregnant women. With low-dose UDCA treatment the obstetric outcome was good. We still recommend careful obstetrical follow-up.

RESUMOO fibro-odontoma ameloblástico é um tumor odontogênico misto benigno, assintomático e raro, que pode ser facilmente confundido radiograficamente e histopatologicamente com outras enfermidades. Normalmente atinge uma população entre a primeira e a segunda décadas de vida, sendo mais frequente em mandíbula e com predileção pelo sexo masculino. Este tumor caracteriza-se pela agenesia dentária no local do tumor, sem predileção por região anatômica, e por um aumento de volume intrabucal, podendo causar leve assimetria facial. Apresenta crescimento lento, porém expansivo; revela-se como uma lesão radiolúcida bem definida, normalmente unilocular, com radiopacidades no seu interior. Normalmente a remoção cirúrgica é conservadora e o prognóstico é favorável. O presente trabalho relata um caso clínico de fibro-odontoma ameloblástico tratado por meio de remoção cirúrgica e com acompanhamento de dois anos. O objetivo deste trabalho foi estudar o fibro-odontoma ameloblástico em sua integralidade, buscando expor ao cirurgião-dentista os melhores métodos de diagnóstico e tratamento para tal lesão.Termos de indexação: Diagnóstico.

127Biofilmes orais como um possível fator de risco ao câncer bucal Oral biofilms as a possible risk factor for oral cancerResumo Introdução: muito se estuda a respeito dos fatores de risco associados ao câncer bucal. Fatores como fumo, álcool e radiação solar já estão bem estabelecidos, porém outros, como a influência bacteriana no desenvolvimento ou progressão de uma neoplasia ainda permanecem inexplicados. O interesse na possibilidade de relação entre bactérias e diferentes estágios do desenvolvimento do câncer aumentou desde a classificação do Helicobacter pylori pela OMS como um carcinógeno definitivo. Subsequentemente, ligações entre infecções e o início de câncer em vários sítios do corpo foram descobertos.Revisão de literatura: esta revisão de literatura buscou demonstrar a influência da má higiene bucal, com consequente acúmulo bacteriano como um possível fator de risco importante ao início e desenvolvimento de neoplasias bucais, bem como correlacionar os possíveis mecanismos pelos quais as bactérias podem iniciar ou promover carcinogênese.Conclusões: existem muitas evidências de que bactérias presentes da cavidade bucal e periodontopatogênicas encontram-se presentes em tecidos neoplásicos, porém, ainda não se pode afirmar que tais bactérias iniciem ou promovam carcinogênese. Palavras-chave:Microbiologia; Câncer Bucal; Biofilme Dentário. AbstRACtIntroduction: much studies regarding risk factors associated with oral cancer. Factors such as smoking and alcohol and solar radiation are well established, but others, such as bacterial influence in the development or progression of a tumor still remain unexplained. Interest in the possible relationship between bacteria and different stages of cancer development has increased since the classification of H. pylori by the WHO as a definite carcinogen. Subsequently, links between infection and the onset of cancer in various sites in the body were discovered.Review of literature: this literature review attempts to show the influence of poor oral hygiene, with consequent bacterial accumulation as a possible important risk factor for the initiation and development of mouth cancer, and correlate the possible mechanisms by which bacteria can initiate or promote carcinogenesis. Conclusion:there is much evidence that bacteria in the oral cavity and periodontopathic are present in tumor tissue, however, still can not affirm that these bacteria initiate or promote carcinogenesis.

Objetivo: Este estudo tem por objetivo revisar a literatura acerca do impacto da cirurgia ortognática na qualidade de vida de pacientes com diferentes deformidades orofaciais e identificar a concepção e percepção dos pacientes em relação às correções de deformidades faciais de um quadro prévio ao procedimento até o momento da avaliação. Metodologia: Foi realizado um levantamento da literatura através das bases de dados PubMed e Medline utilizando os seguintes termos de busca: "ortognática", "distúrbios temporomandibulares", "qualidade de vida" e "psicossocial". Os artigos foram escolhidos nas línguas portuguesa e inglesa entre os anos de 1990 a 2019. Considerações finais: A correção das deformidades esqueléticas faciais e das irregularidades dentárias associadas, pela cirurgia ortognática, apresentam um impacto positivo na qualidade de vida dos pacientes através da melhora harmônica dos ossos esqueléticos faciais, resultando em uma estética facial favorável e em um aprimoramento das funções do sistema estomatognático.

OBJECTIVES:This research evaluated detail registration in peri-implant bone using two different cone beam computer tomography systems and a digital periapical radiograph.METHODS:Three different image acquisition protocols were established for each cone beam computer tomography apparatus, and three clinical situations were simulated in an ex vivo fresh pig mandible: buccal bone defect, peri-implant bone defect, and bone contact. Data were subjected to two analyses: quantitative and qualitative. The quantitative analyses involved a comparison of real specimen measures using a digital caliper in three regions of the preserved buccal bone – A, B and E (control group) – to cone beam computer tomography images obtained with different protocols (kp1, kp2, kp3, ip1, ip2, and ip3). In the qualitative analyses, the ability to register peri-implant details via tomography and digital periapical radiography was verified, as indicated by twelve evaluators. Data were analyzed with ANOVA and Tukey’s test (α=0.05).RESULTS:The quantitative assessment showed means statistically equal to those of the control group under the following conditions: buccal bone defect B and E with kp1 and ip1, peri-implant bone defect E with kp2 and kp3, and bone contact A with kp1, kp2, kp3, and ip2. Qualitatively, only bone contacts were significantly different among the assessments, and the p3 results differed from the p1 and p2 results. The other results were statistically equivalent.CONCLUSIONS:The registration of peri-implant details was influenced by the image acquisition protocol, although metal artifacts were produced in all situations. The evaluators preferred the Kodak 9000 3D cone beam computer tomography in most cases. The evaluators identified buccal bone defects better with cone beam computer tomography and identified peri-implant bone defects better with digital periapical radiography.
