本研究的目的是使用流动颗粒分析仪（Sysmex FPIA-3000，日本神户）表征有效尺寸范围为 1.5-160 μm 的各种三氧化二矿物骨料 (MTA)（ProRoot MTA/MTA Angelus/Gray and White）和波特兰水泥的粒度分布和圆形度。对于灰色 ProRoot MTA、白色 ProRoot MTA、灰色 MTA Angelus、白色 MTA Angelus 和波特兰水泥，6 至 10 μm 颗粒的累积百分比分别为 65%、73%、48%、53% 和 70%。 ProRoot MTA 比 MTA Angelus 含有更少的大颗粒。 MTA Angelus 比 ProRoot MTA 含有更多数量的小颗粒。与灰色 MTA 相比，白色 MTA 含有更小的颗粒，其尺寸分布范围更窄。 MTA Angelus 颗粒具有相对较低的圆形度和较宽的尺寸分布，并且不如 ProRoot MTA 均匀。
The aim of this study is to characterize the particle size distribution and circularity of various Mineral Trioxide Aggregates (MTA) (ProRoot MTA/ MTA Angelus/Gray and White) and Portland cements with effective size ranges of 1.5-160 mu m using a flow particle analyzer (Sysmex FPIA-3000, Kobe, Japan). Cumulative percentage of particles between 6 and 10 mu m were, 65, 73, 48, 53, and 70%, for Gray ProRoot MTA, White ProRoot MTA, Gray MTA Angelus, White MTA Angelus, and Portland cement, respectively. ProRoot MTA contains fewer large particles than MTA Angelus. MTA Angelus contains a higher number of small particles than ProRoot MTA. White MTA contains smaller particles with a narrower range of size distribution than Gray MTA. MTA Angelus particles have relatively low circularity and wide size distribution and are less homogeneous than ProRoot MTA.
