Introdução: A reabsorção inflamatória interna é uma condição rara, caracterizada por uma inflamação crônica da polpa, apresentando a formação de tecido de granulação com exposição de dentina mineralizada. Quando uma perfuração é detectada, o tratamento conservador ou cirúrgico pode ser indicado. Objetivo: O presente relato de caso descreve uma reabsorção interna perfurante de rápida evolução em molar inferior, que foi tratada com Agregado de Trióxido Mineral (MTA) como material obturador. Relato de caso: Paciente do sexo feminino, 23 anos de idade, apresentou dor à mastigação no dente #36. Foi estabelecido o diagnóstico de periodontite apical aguda causada por contato prematuro, e o tratamento foi ajuste oclusal associado à prescrição de anti-inflamatório. Seis meses depois, nenhum sintoma foi relatado. Porém, a radiografia periapical mostrou uma reabsorção interna de grande dimensão na raiz mesial, associada à lesão de furca. Ao exame tomográfico, foi possível observar a presença de reabsorção interna do tipo perfurante. O tratamento endodôntico foi realizado e o canal foi obturado com MTA. Resultados: No acompanhamento de dois anos, as imagens tomográficas do dente mostraram cicatrização total do tecido ósseo e o dente estava clinicamente em função e sem sintomas. Conclusões: O tratamento de uma reabsorção interna perfurante pode ser conduzido com sucesso sem intervenção cirúrgica, quando um material bioativo apropriado é utilizado para preencher o canal. No entanto, um efetivo preparo biomecânico do sistema de canais radiculares deve ser realizado para se alcançar esse resultado. [ABSTRACT FROM AUTHOR]

Introdução: A probabilidade de melhoria do espaço aéreo superior (EAS) com cirurgia ortognática deve ser considerada durante a decisão do tratamento ortodôntico-cirúrgico, proporcionando não somente um benefício estético, mas também funcional, para o paciente. Objetivo: O objetivo do presente estudo foi avaliar as alterações 3D no espaço das vias aéreas superiores após a cirurgia de avanço maxilomandibular (AMM). Métodos: Foi realizada uma análise retrospectiva de 56 pacientes, 21 homens e 35 mulheres, com média de idade de 35,8 ± 10,7 anos, submetidos a AMM. Foram obtidas tomografias computadorizadas de feixe cônico (TCFC) pré- e pós-operatórias para cada paciente, e as alterações no EAS foram comparadas usando o software Dolphin Imaging v. 11.7. Foram medidos dois parâmetros do espaço aéreo faríngeo (EAF): volume das vias aéreas (VVA) e área axial mínima (AAM). Foi utilizado o teste t pareado para comparar os dados entre T0 e T1, com nível de significância de 5%. Resultados: Houve um aumento estatisticamente significativo no EAS. A cirurgia de avanço bimaxilar aumentou o volume das vias aéreas (VVA) e a área axial mínima (AAM) em média 73,6 ± 74,75% e 113,5 ± 123,87%, respectivamente. Conclusão: A cirurgia de AMM tende a causar o aumento significativo do EAS; no entanto, esse aumento é altamente variável. [ABSTRACT FROM AUTHOR]

Introdução: A periodontite apical assintomática (PAA) é caracterizada pela inflamação e destruição dos tecidos periapicais, e sua progressão promove reabsorção óssea, podendo ser agravada pelo uso contínuo de isotretinoína. Objetivo: O objetivo do presente estudo foi relatar a resolução de uma PAA com rompimento de cortical óssea mandibular em um paciente sob tratamento contínuo com isotretinoína (Roacutan®), por meio de procedimentos químicos-mecânicos convencionais e controle com tomografia computadorizada de feixe cônico (TCFC). Descrição: Um paciente com 21 anos de idade, ASA I, em tratamento contínuo com isotretinoína, procurou atendimento odontológico com moderada dor na região do elemento dental #38. Após exames clínicos, radiográficos e tomográficos, verificou-se a necessidade de tratamento endodôntico do dente #36. A TCFC mostrou uma imagem apical extensa e hipodensa entre os dentes #36 e #37, compatível com lesão cística óssea, com dimensões de 25,59 mm (largura) x 14,37 mm (altura) x 8,40 mm (profundidade). Também foram observados reabsorção apical da raiz distal, halo hipodenso sob a restauração coronal do #36 e ruptura da cortical externa vestibular e lingual. O tratamento endodôntico foi realizado em três sessões, com auxílio de um microscópio operatório e protocolos químicos-mecânicos, como Easy Clean e terapia fotodinâmica. Resultado: A resolução da PAA foi observada após acompanhamento por três anos. Conclusão: O tratamento endodôntico permitiu o reparo de uma lesão periapical extensa, evitando a cirurgia parendodôntica imediata, e o uso contínuo de isotretinoína não afetou a resolução da PAA.

Introdução: O estudo da anatomia da raiz e do canal radicular tem importância relevante para o tratamento endodôntico. Portanto, o conhecimento da morfologia do canal radicular é essencial para se realizar um tratamento que resulte em sucesso. No entanto, o profissional tem limitada informação desses conhecimentos, e um acesso difícil ao local de atuação. Objetivo: O presente estudo teve por objetivo avaliar o número de canais de incisivos inferiores, visto que estudos realizados sobre o assunto apresentam uma alta taxa de incisivos inferiores com dois canais radiculares. Métodos: Para avaliar com detalhes a anatomia interna das raízes dos incisivos inferiores, foi utilizada a tomografia computadorizada de feixe cônico (TCFC) na observação dos canais radiculares, em dentes permanentes humanos. Foram analisadas 97 imagens tomográficas obtidas com um tomógrafo Orthopantomograph OP 300 (Instrumentarium, Tuusula, Finlândia) de pacientes que se submeteram ao exame por motivos diversos. Todos os grupos dentários foram avaliados individualmente, e sua morfologia interna foi determinada conforme a Classificação de Vertucci (1984). Resultados: Os resultados observados por meio do teste estatístico do qui-quadrado apresentaram maior frequência dos Tipos I e III (Classificação de Vertucci), em comparação aos outros tipos (p < 0,001). Conclusão: Conclui-se que a TCFC é o recurso viável para auxiliar a prática endodôntica, especialmente em casos complexos, como a localização de canais radiculares. A ocorrência de mais de um canal em incisivos inferiores centrais e laterais foi de 23,71% nesse estudo realizado na população brasileira. [ABSTRACT FROM AUTHOR]
