Objective: This study aims to clarify to the dentist about the possible etiological factors responsible for such complication, to identify its clinical and radiographic signs and to describe the surgical technique adopted in these cases. Case Report: For this purpose, the authors present the clinical case of a patient with post-exodontia oroantral fistula of the right permanent maxillary first molar. The proposed treatment was the closure of the fistula under local anesthesia using the Bichat adipose body, with advantages of being a simple procedure, easy to perform, that does not require specific material, minimal complications, low morbidity and can be performed in the own dental practice and with high success rates proven by several studies. Discussion: The oroantral fistula is a common pathological occurrence in the dental clinic, characterized by communication of the maxillary sinus with the oral cavity when the maxillary sinus is pneumatic or during dental extractions of upper posterior elements whose roots are closely related to the maxillary sinus. Conclusion: Communications should be treated immediately, if there are signs of inflammation it should be treated first, so that surgical correction can be performed later.

Objetivo: descrever uma revisão da literatura que apresente as principais consequências que podem ocorrer quando o dente avulsionado é reimplantado de forma tardia, proporcionando um prognóstico desfavorável. Revisão de literatura: a avulsão dental é uma lesão traumática que se caracteriza pelo completo deslocamento do dente de seu alvéolo, acarretando danos tanto às estruturas de suporte do elemento dental quanto às estruturas pulpares. A permanência extraoral do elemento dental avulsionado por períodos longos ou em meios de armazenamento inadequados pode provocar danos adicionais. Considerações finais: as lesões de inserções são as principais consequências da pós-avulsão dentária, isso devido a uma ruptura do ligamento periodontal, com uma secagem excessiva antes do reimplante, danificando as células do ligamento periodontal, o que, por sua vez, provoca uma resposta inflamatória exacerbada em uma ampla área da superfície radicular.Palavras-chaves: Avulsão dentária. Reimplante dentário. Traumatismos dentários. IntroduçãoO traumatismo dentário apresenta-se como um problema de saúde pública comumente encontrado entre crianças e adolescentes, sendo que a avulsão dental compreende 16% desses traumas 1 . Isso gera um elevado impacto psicossocial, com necessidade de tratamentos de alto custo, já que, aos gastos iniciais do atendimento emergencial, somam-se aqueles de controle pós-tratamento, que pode se estender por vários anos após o trauma. Entre as principais causas, podemos citar os acidentes automobilísticos, os esportes de contato e a violência urbana 2 .O reimplante de dentes tem sido considerado como uma medida temporária, já que muitos dentes não resistem à reabsorção radicular que ocorre a partir da reabsorção superficial do cemento, podendo levar ao reparo ou à reabsorção por substituição, que resultará em anquilose progressiva 3 . A necrose isquêmica da polpa também pode ocorrer, seguida de regeneração ou degeneração pulpar 4 .Reabsorção inflamatória, reabsorção por substituição e esfoliação do dente são complicações potenciais quando dentes avulsionados são reimplantados; na maioria dos casos, é possível que o dente acometido apresente necrose pulpar, em função do rompimento do feixe vásculo-nervoso 5 . No que diz respeito a ligamento periodontal e cemento, as principais consequências são: reabsorção superficial do cemento acelular, seguida de reparo normal do

Objective: The present study aims to expose through a literature review the cleft lip and/or cleft palate (CL/CP) and its treatment in a multidisciplinary approach. Methodology: This literature review was conducted by the leading health databases: Pubmed (https://www.ncbi.nlm.nih.gov/pubmed). The keywords for the textual search were: Cleft Lip; Cleft Palate; Dental Staff; Classification; Embryology. The inclusion criteria were: literature on the subject under study, literature of the last years, english language, laboratory and clinical studies and systematic review. Literature Review: Fissures can be defined by a space at the junction between two bones, usually where there would be a suture. Orofacial clefts are part of the congenital facial anomalies resulted from the non-junction of the embryonic facial processes. These changes occur due to an alteration in the migratory velocity of the neural crest cells, in charge of the phenomenon of fusion of the facial prominences between the 6th and 9thweek of embryonic life. Conclusion: The treatment of patients with orofacial clefts requires the approach of a multidisciplinary team that involves physicians in the area of plastic surgery, otorhinolaryngology, pediatrics, geneticists, dentists, prosthetics, nurses and speech pathologists, focusing on patient prevention, recovery and rehabilitation. However, further studies are needed for a better understanding of the subject and the steps that should be applied for each particular case.Descriptors: Cleft Lip; Cleft Palate; Dental Staff; Classification; Embryology.ReferencesShaw WC, Brattström V, Mølsted K, Prahl-Andersen B, Roberts CT, Semb G.

Introduction: In cases where there is an association of two or more diseases, it’s complex to improve individual’s well-being and quality of life, especially when these diseases have a bidirectional relation, as observed between diabetes mellitus and periodontal disease. Aim: The present study aims to review the literature on the relation between Diabetes Mellitus and Periodontal Disease, identifying the main aspects and pathognomonic characteristics.Conclusion:Due to the exposed in the literature on the interrelation of diabetes mellitus and periodontal disease, further studies are needed for a better understanding of the subject, knowing that the interdisciplinary approach is very important for the patient to have a better quality of life.

Objetivo: Demostrar as considerações atuais no diagnóstico, mudança na classificação e abordagem terapêuticas, para o tratamento dos ameloblastomas. Método: trata-se de revisão narrativa de literatura aliada a demonstração de casos clínicos originais com o propósito de aproximar o conteúdo teórico revisto com exemplares de aplicação prática da atuação do profissional.  A consulta pela literatura pautou-se em livros de referência mundial como o da Organização Mundial da Saúde associado a busca eletrônica nas bases de dados Medline, Lilacs e SciELO. Resultados: O ameloblastoma é uma neoplasia odontogênica benigna de evolução lenta, assintomática. Em aspecto de exames de imagem as lesões variam entre o radiolúcido unilocular ao multilocular, podendo provocar alterações em dentes próximos. Em aspecto transcirúrgico e histopatológico há diferenças entre ameloblastoma e ameloblastoma cístico para as lesões intraósseas, e o tratamento será influenciado por esse fator, além de idade do paciente, tamanho da lesão e localização. Há ainda na literatura uma certa preferência para as abordagens radicais. As terapias direcionadas contra o gene BRAF parecem um futuro promissor. Conclusão: O conhecimento de variantes do ameloblastoma é primordial e orienta uma reflexão terapêutica do tipo custo/benefício a ser estabelecida em cada caso individualmente a partir de discussão multidisciplinar e escolha do paciente.
