Objetivo: Discutir os resultados do procedimento de aumento de coroa clínica com finalidade estética, apresentando dois casos clínicos de pacientes com hiperplasia gengival e erupção dental passiva alterada. Detalhamento do Caso: Ambos os pacientes compareceram ao Complexo Odontológico São João Calábria da UNICATÓLICA queixando-se da estética de seus sorrisos. Após os exames, constatou-se saúde periodontal, porém havia notória relação desarmônica entre o comprimento e o formato dos dentes, bem como alta exposição de tecido gengival ao sorrir. Foram realizadas sondagem transulcular, fotografias e exame radiográfico. Os pacientes assinaram o Termo de Consentimento Livre e Esclarecido. No caso da erupção passiva alterada, optou-se por bisel interno sem descolamento de retalho seguido do refinamento das margens gengivais com tesoura Castroviejo. No caso de hiperplasia gengival, a técnica escolhida foi de bisel externo junto com o procedimento de peeling gengival seguido da frenectomia labial superior. Os dois pacientes foram acompanhados pelo período de 7,14, 90 e 150 dias, não apresentaram queixas estéticas e se mostraram satisfeitos com o resultado final. Considerações finais: Para a realização da gengivectomia vários fatores devem ser analisados previamente ao procedimento, entre eles fatores estéticos, biótipo periodontal, a causa da alteração e a necessidade ou não de osteotomia.
Introduction: General anaesthesia has been used worldwide since its first public demonstration with ether in 1846. Until a little more than a decade ago, it was believed that the anaesthetic state was limited to the period of exposure. Studies in rats, pigs, and rhesus monkeys have shown that almost all general anaesthetics accelerate the apoptotic process in neurones, oligodendrocytes, and glial cells. Objective: Our aim was to analyse the relationship between general anaesthetics and their role in triggering neuroapoptosis in laboratory animals. Method: A search was carried out in PubMed and Google Scholar with the keywords "neurotoxicity" and "general anesthetics" for selecting articles published in the last five years. After having evaluated the abstracts, 77 articles were selected and read by 2 independent investigators. All authors met and discussed the most relevant aspects. Results: All general anaesthetics, when inhaled or administered intravenously, enhance neuroapoptosis, mainly during the gestational and neonatal stages in rats, pigs, and non-human primates. Neurones and oligodendrocytes that are capable of neurogenesis and synaptogenesis are the most affected. General anaesthetics commonly lead to learning and behavioural disorders, in addition to permanent memory deficit. Conclusion: The neurotoxicity of general anaesthetics affects different mammalian species and accelerates the neuroapoptotic process. This deleterious effect involves specific brain areas and occurs in developing neurones. The exceptions are the dentate gyrus and the olfactory bulb, which undergo apoptosis even in adulthood, albeit to a lesser extent.
The Aneurysmal Bone Cyst (ABC) is an expansive osteolytic, radiolucent, multilocular, eccentric lesion of unknown origin consisting of spaces filled with blood in any segment of the skeleton, being most frequently encountered in the diaphysis of the long bones or the spinal cord. It may occur as distinct clinico-pathological entity or as pathophysiological alteration of a preexisting lesion, like giant-cells lesion, fibrous dysplasia, ossifying fibroma, osteoblastoma, epiphysary chondroblastoma and even malignant lesions such as osteossarcoma. This paper reports a rare case of ABC in the zygomatic arch of a young female patient who presented facial asymmetry and progressive limitation in mouth opening, treated by resective surgical procedure and discusses the clinical, radiological and histological features of this pathology along with its treatment.
Objective: to analyze the oral health profile of inpatients victims of oral and maxillofacial trauma at the Institute Dr. José Frota Hospital, Ceará, Brazil. Methodology: a study carried out in 2020 started with an examination of the oral cavity at the bedside, application of the DMFT and The Bedside Oral Exam indexes, together with the survey of dental needs and application of the Oral Health Impact Profile Scale (OHIP-14), relating the findings, applying average, standard deviation and calculating Cronbach's alpha coefficient and Spearman's correlation for the OHIP-14 finding. Results: We evaluated 78 patients, mostly male (88%), with a mean age of 32.72 ± 11.63 years old, with hypertension being the most prevalent comorbidity. Besides, 60% of the sample had a fracture in the lower third of the face. The average number of decayed teeth per patient was 5.69. About 62.82% had poor oral health, seen from generalized biofilm and swollen gums. Low-Level Laser therapy was indicated for 94.8% of the sample, periodontal treatment in 58.9%, restorative therapy in 69.2%, and surgical in 42.3%. Regarding the OHIP-14 questionnaire, facial trauma negatively impacted the participants' quality of life, especially in dimensions related to pain. Conclusion: there was a significant prevalence of oral diseases, such as gingivitis and dental caries, which justifies the need for dental intervention before the maxillofacial surgical approach.
Para a realização do retratamento endodôntico, a remoção do material obturador geralmente é obtida através da ação mecânica dos instrumentos e química dos solventes. O objetivo deste trabalho foi realizar uma revisão de literatura acerca da eficácia dos solventes utilizados em reintervenções na endodontia. Para tanto, foram pesquisados artigos científicos dos últimos 10 anos em inglês e português nas bases de dados Pubmed, Lilacs e Scielo utilizando as palavras-chave: “retreatment”, “solvents” e “endodontic”. A pesquisa resultou em 32 artigos não duplicados. Após análise dos títulos e resumos 10 foram selecionados. Como critério de inclusão foram considerados estudos clínicos ou laboratoriais utilizando dentes humanos e excluídas revisões de literatura e revisões sistemáticas. Por meio da análise da literatura atual, concluiu-se que é importante a associação da rapidez de atuação e da biocompatibilidade. Contudo, todos os solventes utilizados têm efeitos citotóxicos. O clorofórmio e o xilol exibem uma elevada capacidade de solvência, mas também considerável toxicidade. O óleo da casca de laranja tem sido indicado como o solvente de menor potencial irritativo, mas estudos exibem divergências quanto à capacidade de amolecimento da guta-percha em relação a outras substâncias. A partir do cenário atual, infere-se que ainda são necessários mais estudos em relação aos solventes para que o clínico possa realizar uma escolha mais eficaz e segura para cada caso.Palavras-chave: Endodontia. Retratamento. Solventes.
