Abstract
Objetivo: o objetivo desta pesquisa foi avaliar o tempo e o fluxo de endurecimento do cimento AH-PLUS e MTA nas proporções de 10%, 20% e 30%, a fim de adicionar a capacidade de estimular a deposição de tecido duro. Material e Métodos: Para o teste de fluxo, 0,5 ml de cimento foram depositados em uma placa de vidro e outra placa foi adicionada com uma carga adicional, após 10 minutos a carga foi removida e o diâmetro do círculo formado pelo cimento foi medido com um Bússola digital. Para o tempo de endurecimento, foram utilizados moldes cilíndricos preenchidos com o cimento testado, mantidos dentro de um forno e os testes de agulha de Gillmore foram realizados no material em intervalos de 60 segundos até que as marcas não fossem visíveis na superfície do cimento testado. Resultados: Na vazão, os valores obtidos foram: 41,1 mm (10% MTA), 32,86 mm (20% MTA), 21,91 mm (30% MTA), 24,41 mm AHPlus® e 26,47 mm MTA Fillapex®. O tempo de endurecimento encontrado nesta pesquisa foi de 1631 'em proporção (10% MTA), 628,4 em proporção (20% MTA), 567' em proporção (30% MTA), 767 em AH Plus e Fillapex MTA não. presou dentro de 6 semanas. Conclusão: concluiu-se que a adição de 10%, 20% e 30% de MTA ao AH Plus não alterou as propriedades do fluxo e o tempo estabelecido.
Highlights
Endodontics is the field of dentistry that studies the pulp cavity morphology, the physiology and pathology of the dental pulp as well as the prevention and treatment of pulp alterations and their repercussions on the periodontal tissues.[1]
The flow of obturator sealers consists in their ability to penetrate irregularities, root canal system branches and dentinal tubules
The set formed by the specimen/glass slide/ metal cylinder was inside the climate chamber until the end of the test
Summary
Endodontics is the field of dentistry that studies the pulp cavity morphology, the physiology and pathology of the dental pulp as well as the prevention and treatment of pulp alterations and their repercussions on the periodontal tissues.[1] Obtaining a root canal means filling it to the fullest extent with an inert or antisetic material, hermetically sealing it, not interfering and preferably stimulating the apical and periapical repair process.[2] Obtaining an airtight seal after proper root canal cleaning and mo-deling is one of the keys to achieving long-term endodontic treatment success.[3] The f low property of obturator cement is evaluated by the methodology proposed by ANSI/ADA Standard No 57. The greater the fluidity of the material, the greater its penetration capacity, there is a greater chance of material leakage and, damage to the periapical tissue.[4]
