Abstract(s)
O Agregado de Trióxido Mineral (MTA) foi inicialmente utilizado como material
retrobturador, e posteriormente, usado também em diversas circunstâncias clínicas. A
ampliação das indicações do MTA foi baseada na ótima qualidade das suas
características físicas e biológicas, nas quais se destacam a excelente eficiência de
selamento e sua da significativa bioatividade.
No entanto, o MTA tem diversas desvantagens como material de cobertura, tais como:
ser de difícil manuseio, apresentar extenso tempo de endurecimento, induzir a
descoloração dos elementos dentários e incompatibilidade com outros materiais
quando em camadas.
BiodentineTM (BD) tem sido frequentemente reconhecido na literatura como um
material promissor e serve como um importante representante dos cimentos à base de
silicato tricálcico utilizados na medicina dentária. Os fabricantes afirmam que BD
possui boas propriedades mecânicas, além de excelente biocompatibilidade e
comportamento bioativo. Além disso, tem um tempo de endurecimento inicial de 6
min e tempo de presa final de 10-12min, e não causa descoloração dos dentes.
O trabalho tem como alvo proporcionar uma atualização sobre as propriedades físicas
e biológicas de BD e comparar estas propriedades com o cimento MTA. Novos
materiais que exigem melhor desempenho estão continuamente a ser introduzidos no
mercado para aperfeiçoar o tratamento dos dentes.
O objetivo deste estudo é fazer uma revisão de literatura, até os dias atuais, sobre as
propriedades químicas, físicas e biológicas de BiodentineTM (BD) e Agredado
Trióxido Mineral (MTA).
The MTA was preliminarily identified as retrofilling material, and later, also used in other clinical situations. The expansion of MTA indications was based on the excellent quality of its physical and biological characteristics, in which the excellent sealing efficiency and its significant bioactivity stand out. However, the MTA exhibits several disadvantages such as covering material, being difficult to handle, presenting long hardening times, inducing discoloration of dental elements and incompatibility with other materials when layered. BiodentineTM has often been recognized in the literature as a promising material and serves as an important representative of tricalcium silicate cements used in dentistry. Manufacturers claim that BiodentineTM has good mechanical properties, in addition to excellent biocompatibility and bioactive behavior. In addition, initial setting time of 6 min and final setting time of 10-12 min, and does not cause discoloration of the teeth. The aim of the work is to provide an update on the physical and biological properties of BiodentineTM and to compare these properties with MTA cement. New materials claiming better performance are continually being introduced to the market to optimize the treatment of patients. The purpose of this study is to review the literature, chronologically, on the chemical, physical and biological properties of BiodentineTM and Aggregate Mineral Trioxide (MTA).
