Abstract

This study evaluated the chemical, mechanical, and biocompatibility of Portland cement (PC) with different proportions of niobium oxide (Nb₂O₅). Five male Wistar rats were used. Four polyethylene tubes were placed on the dorsal subcutaneous tissue: one tube empty (NC), one tube MTA (Angelus®), one tube contained F6 (PC, Nb₂O₅ and CaSO₄), and one tube F7 (PC, Bi₂O₃, Nb₂O₅ and CaSO₄). After 60 days, animals were euthanized, and tubes were removed with the surrounding tissues. Inflammatory infiltrates were stained with hematoxylin–eosin. Mineralization was analyzed using Von Kossa staining and polarized light. The F6 showed small vessels and dispersed mononuclear inflammatory cells, score of 1 (1–2), p˃0.05 vs. NC 0.5 (0–1), and the absence of cell giants. Positive Von Kossa staining and birefringent structures under polarized light were observed with MTA, F6, and F7. The niobium oxide (Nb₂O₅), in association with Portland cement, exhibits calcium crystals and biocompatibility in rat subcutaneous tissue.

与铌有关的硅酸盐水泥在大鼠皮下组织中的钙结晶和生物相容性证明了这一点

本研究评估了含有不同比例氧化铌（Nb2O5）的硅酸盐水泥（PC）的化学、机械和生物相容性。研究使用了五只雄性 Wistar 大鼠。在背侧皮下组织上放置了四根聚乙烯管：一根空管（NC）、一根 MTA 管（Angelus®）、一根含有 F6（PC、Nb2O5 和 CaSO4）的管子和一根 F7（PC、Bi2O3、Nb2O5 和 CaSO4）的管子。60 天后，动物被安乐死，管子和周围组织一起被移除。用苏木精-伊红对炎性浸润进行染色。使用 Von Kossa 染色法和偏振光分析矿化情况。F6 显示小血管和分散的单核炎症细胞，评分为 1（1-2），p˃0.05 与 NC 0.5（0-1）相比，没有细胞巨头。用 MTA、F6 和 F7 观察到阳性 Von Kossa 染色和偏振光下的双折射结构。氧化铌（Nb2O5）与波特兰水泥结合，在大鼠皮下组织中显示出钙结晶和生物相容性。
