Resumo

A manutenção do elemento decíduo na arcada tem fundamental importância no estabelecimento de uma oclusão normal, principalmente em casos de agenesia dental. A proteção pulpar direta é um tratamento conservador que visa à manutenção da vitalidade pulpar e possibilita a permanência do elemento dental na arcada. Um material recentemente utilizado é o Agregado Trióxido Mineral, devido às suas propriedades favoráveis, como atividade antimicrobiana e alta biocompatibilidade. Desta forma, o presente trabalho objetivou relatar um caso clínico de proteção pulpar direta com Agregado Trióxido Mineral em um molar decíduo com agenesia do sucessor permanente. Após o procedimento de proteção pulpar direta, as respostas teciduais foram acompanhadas clínica e radiograficamente durante dois anos e dois meses. Não foi observada a formação de tecido dentário, devido à avançada idade dentária. Entretanto, o Agregado Trióxido Mineral funcionou como uma barreira física capaz de vedar o tecido pulpar, mantendo-se a vitalidade pulpar, com ausência de sintomatologia dolorosa; demonstrou-se, assim, ser um material eficiente para o tratamento conservador pulpar direto de dentes decíduos, mesmo com idade dental avançada e agenesia do elemento sucessor.

Abstract

The preservation of primary teeth in arch has fundamental importance on establishing of normal occlusion, mainly in cases of teeth agenesis. Direct pulp protection is a conservator treatment which main objective is the maintenance of pulp vitality and teeth function in arch. Mineral Trioxide Aggregate is a material used due to favorable properties as antimicrobial activity and high biocompatibility. Therefore, the objective of the present work was to relate a case report of direct pulp protection with Mineral Trioxide Aggregate in a primary molar with successor permanent agenesis. After direct pulp protection procedures, tissue responses were clinically and radiographically assessed during two years and two months. It was not observed dental tissue formation, probably due to advanced dental age. Mineral Trioxide Aggregate act as physical barrier, isolating pulp tissue, maintaining teeth vitality and absence of pain, thus demonstrating efficiency, even in teeth with advanced age mainly in cases of tooth agenesis.

Keywords
