O conhecimento da anatomia é um dos fatores primordiais para o sucesso da comparação de registros dentários durante uma investigação de um indivíduo na odontologia forense. Para realizar esse tipo de procedimento, o profissional deve estar apto a identificar e diferenciar estruturas anatômicas do complexo maxilofacial. O objetivo desse estudo foi verificar se existe correlação entre ângulo goníaco e o forame mentoniano a idade e o gênero, de pacientes submetidos à exames de Tomografia Computadorizada da mandíbula. A metodologia desse trabalho baseou-se na obtenção e análise dos arquivos DICOM, de forma que estas imagens foram convertidas para um programa específico de tratamento de imagens ImplantViewer (Anne Solutions, São Paulo, Brasil), e avaliadas utilizando a Janela Panorâmica e Cortes Transversais de Tomografias Computadorizadas. Indivíduos do gênero masculino apresentaram o forame mentoniano mais distante da crista alveolar do que os indivíduos do gênero feminino. A TCFC é uma importante ferramenta na visualização das estruturas anatômicas, favorecendo as atividades inerentes a Odontologia Forense. Neste estudo, o gênero masculino apresentou o forame mentoniano mais distante da crista alveolar do que o gênero feminino.
Pulp necrosis in immature permanent teeth represents a challenge for clinical management. The dentin wall in immature teeth is thin and the root is short, leading to an unfavorable long-term prognosis due to the risk of root fracture. Regenerative endodontic procedures have been shown to be effective and improve the prognosis of the compromised immature tooth by re-establishing functional pulp tissue that promotes continued root development and immune competence. The objective of the study was to report a case of a young permanent molar, diagnosed with necrosis and incomplete rhizogenesis. A female patient, 08 years old, attended the clinic of the specialization course in Endodontics, Faculty of Dentistry São Leopoldo Mandic, Belo Horizonte Unit. Regenerative therapy was proposed, which involved the following steps: anesthesia, opening, odontometry, minimal instrumentation, disinfection with 2% chlorhexidine gel, irrigation with saline solution, intracanal medication with calcium hydroxide paste, induction of bleeding to form a blood clot, cervical sealing with mineral trioxide aggregate and composite resin. The patient remained symptom-free up to 5 months after treatment. However, radiographically, an increase in the periapical radiolucent area was noted, so it was decided to carry out the conventional endodontic treatment. Regenerative therapy can be an alternative to apexification in immature teeth in cases of irreversible pulpitis and pulp necrosis associated or not with a periapicalesionson. It is a simple treatment with advantageous results as it promotes an increase in the length and thickness of the dentin wall and apical closure as seen in the case described in this work.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
