“…The physical properties of MTA render handling difficult, and can even make it impossible to remove the material if endodontic retreatment is needed. 6,23 Tooth crown discoloration, attributed to a possible chemical reaction, may occur even with use of white MTA, 24 and the higher cost of MTA compared with Ca(OH) 2 is another factor to be considered.…”

Delayed tooth replantation: MTA as root canal filling

et al. 2014

MTA has been investigated as a root-end filling material. Its mechanism of action has some similarities to that of Ca(OH) 2 . The purpose of this study was to evaluate the repair process taking place in the delayed replantation of monkey teeth using calcium hydroxide and MTA as root canal filling materials. Five monkeys had their lateral incisors extracted and bench-dried for 60 minutes. After root canal preparation, the teeth were assigned to two groups according to root canal filling material: I, calcium hydroxide; and II, MTA. The same treatment sequence was followed for both groups: coronal seal, periodontal ligament removal, immersion of the tooth in 2% acidulated-phosphate sodium fluoride, irrigation of the socket with saline and replantation. Both groups exhibited replacement resorption, areas of ankylosis and absence of inflammatory root resorption. Statistically similar results (p > 0.05) were observed for both groups regarding replacement root resorption, but the groups differed significantly (p < 0.05) regarding the occurrence of ankylosis. MTA may be a viable clinical option for filling teeth submitted to delayed replantation, and is an acceptable option for treating replanted permanent teeth in order to prevent tooth resorption, particularly when dressing changes are not possible.

“…As the hydration rate of dicalcium silicate is lower than that of tricalcium silicate 18 , the compressive force 14 of MTA reaches its maximum several days after mixing 19 . Various factors may influence the compressive force of MTA, including type of MTA, liquid that is mixed with the material, condensation pressure on the material, pH value of the mixed liquid, and MTA storage condition 16,[20][21][22] . Shabahang et al 23 studied MTA for apexification and concluded that placing an apical MTA cap is a promising alternative to conventional therapy with calcium hydroxide.…”

Apexification is the endodontic procedure performed in order to induce the formation of a physical barrier of mineralized tissue in teeth with RESUMOA apicificação é o procedimento endodôntico realizado para induzir a formação de uma barreira física de tecido mineralizado em dentes com incompleta formação radicular. É realizada, principalmente, quando, por alguma razão, ocorre necrose pulpar em dentes com rizogênese incompleta e, também, nos casos em que o forame se encontra aberto, em função de reabsorção radicular. Nessas situações, o tratamento endodôntico convencional se torna difícil ou quase impossível, por causa do amplo forame. O procedimento de apicificação, nesses casos, é geralmente realizado por meio de trocas sucessivas de curativos de hidróxido de cálcio, com o objetivo de induzir a formação de uma barreira física de tecido mineralizado, possibilitando, então, a obturação dos canais radiculares. O protocolo apresentado neste artigo, bem como os casos clínicos relatados, ilustram uma opção de tratamento mais rápido, realizado em três sessões, utilizando um tampão ou plug de MTA, material que oferece boas propriedades biológicas e físicas.Termos de indexação: Apexificação.

“…In a review article, Alhadain discussed the ideal properties of a perforation repair material. It should be non-toxic, noncorrosive, nonstaining, have bactericidal or bacteriostatic properties, easy to manipulate, set rapidly, well tolerated by periradicular tissues, promote regeneration of periradicular tissues, dimensionally stable, radiopaque, and remain unaffected by the presence of moisture or low pH levels [7].…”
