“…Other factors may also be correlated with MTA darkness, such as the light curing performed when some restorative materials are used. Vallés et al 30 suggest that an association between oxygen supply and light curing alter the color of MTA cement.…”

Analysis of the color alteration and radiopacity promoted by bismuth oxide in calcium silicate cement Abstract: The aim of the study was to determine if the increase in radiopacity provided by bismuth oxide is related to the color alteration of calcium silicate-based cement. Calcium silicate cement (CSC) was mixed with 0%, 15%, 20%, 30% and 50% of bismuth oxide (BO), determined by weight. Mineral trioxide aggregate (MTA) was the control group. The radiopacity test was performed according to ISO 6876/2001. The color was evaluated using the CIE system. The assessments were performed after 24 hours, 7 and 30 days of setting time, using a spectrophotometer to obtain the ∆E, ∆a, ∆b and ∆L values. The statistical analyses were performed using the Kruskal-Wallis/Dunn and ANOVA/ Tukey tests (p < 0.05). The cements in which bismuth oxide was added showed radiopacity corresponding to the ISO recommendations ( > 3 mm equivalent of Al). The MTA group was statistically similar to the CSC / 30% BO group (p > 0.05). In regard to color, the increase of bismuth oxide resulted in a decrease in the ∆E value of the calcium silicate cement. The CSC group presented statistically higher ∆E values than the CSC / 50% BO group (p < 0.05). The comparison between 24 hours and 7 days showed higher ∆E for the MTA group, with statistical differences for the CSC / 15% BO and CSC / 50% BO groups (p < 0.05). After 30 days, CSC showed statistically higher ∆E values than CSC / 30% BO and CSC / 50% BO (p < 0.05). In conclusion, the increase in radiopacity provided by bismuth oxide has no relation to the color alteration of calcium silicate-based cements.

“…Os fatores associados com o seu escurecimento tem sido avaliados e algumas hipóteses sugeridas. A maioria das teorias sugerem que a presença do óxido de bismuto estaria associada com a alteração de cor do MTA (CAMILLERI, 2014;VALLES, et al, 2013b). No estudo, foram utilizados dentes bovinos para a avaliação da alteração da cor dentária após o contato com os cimentos.…”

“…Estudos prévios utilizaram uma metodologia semelhante para avaliar a alteração de cor de cimentos à base de silicato de cálcio (LENHERR, et al, 2012;CAMILLERI, 2014;VALLES, et al, 2013b). As micrografias em microscopia eletrônica de varredura da interface entre o material e a dentina mostraram alterações nas características microestruturais dos materiais em contato com a dentina.…”

“…Tais íons encontram-se na forma de silicato tricálcio, silicato dicálcio, aluminato tricálcio e aluminoferrita tetracálcio (CAMILLERI, 2008a LENHERR, et al, 2012;VALLES, et al, 2013aVALLES, et al, ,2013b. Esta característica é altamente indesejável para materiais endodônticos, principalmente quando utilizados em áreas com comprometimento estético como, por exemplo, em dentes anteriores.…”

“…O óxido de bismuto tem sido apontado como o elemento responsável pelo escurecimento verificado após a utilização do MTA (LENHERR, et al, 2012;VALLES, et al, 2013b). Assim, radiopacificadores alternativos têm sido estudados para substituir o óxido de bismuto .…”
