This reaction produces bismuth carbonate, which is sensitive to light and lead discoloration (21).

Color Stability of NeoMTA Plus and MTA Plus when Mixed with Anti-washout Gel or Distilled Water/Cozunmeye Direngli Jel veya Distile Suyla Hazirlanan NeoMTA Plus ve MTA Plus Materyallerinin Renk Stabilitelerinin Degerlendirilmesi

Therefore, bismuth carbonate has been proposed as radiopacifying agent in PC (6), but the physicochemical and biological properties of this combination have not yet been thoroughly investigated.

The aim of this study is to create a new PC-based material associated with bismuth carbonate to be used as an alternative to MTA.

Samples of PC (Construcola, Rio de Janeiro, Brazil) and PC mixed with 2 wt% (PC 2%), 5 wt% (PC 5%), 10 wt% (PC 10%) and 15 wt% (PC 15%) of bismuth carbonate [[(BiO).sub.2]C[O.sub.3]] (B'Herzog, Rio de Janeiro, Brazil) were prepared.

Table 2 presents the mean and standard deviation of powder required to obtain cement with ideal consistency when mixed with 0.20 mL of distilled water for the groups of PC pure and associated with 2 wt%, 5 wt%, 10 wt% and 15 wt% of bismuth carbonate. Statistically significant differences were not observed between the groups (P<0.05).

Physico-chemical and Biological Properties of a New Portland Cement-based Root Repair Material

based on its variable composition and overall heterogeneous appearance, it is most likely a mixture of secondary copper and bismuth carbonates or oxides probably originating by oxidation of a primary bismuth sulfide mineral.
