This study evaluated and compared the sealer thickness and interfacial adaptation of bioceramic sealers (Sankin Apatite III, MTA Fillapex ® , EndoSequence ® BC) to root dentin against AH Plus ® sealer. Sixty extracted single-root premolars were prepared and equally divided into four groups. Sealers were labeled with 0.1% Rhodamine B fluorescent dye. Roots were dissected along the transverse plane at 1 mm (apical), 3 mm (middle), and 6 mm (coronal) levels. Sealer-to-whole canal area ratio was evaluated. Percentage of gap-containing region to canal circumference was calculated using a confocal laser microscope. Sealer thickness was significantly higher at apical and middle levels than at coronal level. EndoSequence BC had the significantly highest thickness compared with MTA Fillapex and AH Plus. The coronal level had significantly less interfacial gaps compared with apical and middle levels. Bioceramic sealers showed more gaps compared with AH Plus, with no significant differences among them.

“…Em testes de push-out para avaliação da adesão às paredes dentinárias, o MTA Fillapex demonstrou ser inferior 12 ou similar 13 ao cimento AH Plus. Em um trabalho com infiltração de corante azul de metileno 2%, a capacidade de selamento apical de AH Plus e MTA foi semelhante, enquanto MTA Fillapex mostrou maior infiltração 14 . Os testes de infiltração bacteriana usando o cimento MTA Fillapex têm se mostrado divergentes, sendo então considerados semelhantes 4 ou inferiores 5 quando comparados ao AH Plus, apesar de nenhum vedar totalmente os canais 4,5,15 .…”

ResumoIntrodução: O MTA é um importante material de uso na odontologia, com boas propriedades biológicas. As respostas experimentais aos cimentos endodônticos que utilizam este composto no selamento e preenchimento do sistema de canais radiculares, aliados a uma boa instrumentação e limpeza, podem ser importantes no processo de reparo periapical. Objetivo: Avaliar in vitro a profundidade de penetração de dois diferentes cimentos endodônticos nos túbulos dentinários e a infiltração bacteriana em obturações com os cimentos AH Plus e MTA Fillapex. Material e método: 34 pré-molares monorradiculados humanos foram selecionados, suas coroas removidas e suas raízes padronizadas em 16 mm, a seguir foram, então, divididos aleatoriamente em dois grupos de 15 espécimes e instrumentados com o sistema rotatório Pro Taper. Um grupo foi obturado com o cimento AH Plus (Grupo AH) e outro com MTA Fillapex (Grupo FI). Nestes grupos, avaliaram-se a infiltração coronária de bactérias para Enterococcus Faecalis e a profundidade de penetração nos túbulos dentinários. Para a aferição da infiltração bacteriana, usou-se o teste exato de Fisher; para a penetração intratubular, usou-se o teste-t. Resultado: Para a infiltração bacteriana, considerando o número de amostras infiltradas para AH e MTA Fillapex, houve diferença estatística significativa (p=0,0341). Na avaliação da penetração intratubular, a diferença entre os dois grupos de cimentos foi considerada estatisticamente significativa (p=0,0006). Conclusão: Ambos os cimentos apresentaram infiltração bacteriana, sendo que o MTA Fillapex teve pior desempenho. A capacidade de penetração nos túbulos dentinários do AH Plus foi significativamente maior que a do MTA Fillapex.Descritores: Cimentos endodônticos; penetração intratubular; infiltração bacteriana; AH Plus; MTA Fillapex. Abstract Introduction:The MTA is an important use in dentistry material with good biological properties. The experimental responses to sealers using this compound in the sealing and filling of the root canal system, combined with a good instrumentation and cleaning, may be important in the periapical healing process. Objective: To evaluate in vitro penetration depth of two different sealers in dentinal tubules and bacterial infiltration in fillings with AH Plus and MTA Fillapex cements. Material and method: 34 premolars human monorradiculados were selected, their removed and their standardized root crowns in 16mm, after then randomly divided into two groups of 15 specimens, and instrumented with rotary system Pro Taper. One group was obturated with cement AH Plus (group HA) and another MTA Fillapex (FI Group). These groups are evaluated for coronary infiltration of bacteria Enterococcus faecalis and the depth of penetration in the dentinal tubules. For the measurement of bacterial infiltration used Fisher's exact test for Intratubular penetration we used the t-test. Result: For bacterial infiltration, considering the number of infiltrated samples AH and MTA Fillapex, there was a statistically significant difference ...
