  • Various bioactive calcium phosphates such as hydroxyapatite (HA) and carbonate apatite
    (CO3 Ap) have been widely studied due to their biocompatibility and osteoconductivity when
    implanted into bone defects. CO3 Ap has the ability to adapt bone structure and induce bone
    regeneration; so that it can be categorized as resorbable bioactive materials. CO3 Ap induced much
    stronger response such as cell adhesion and actin ring formation to osteoclast-like cells rather than
    HA. The aim of this study is to evaluate the bioactivity on zirconia (Y-TZP) coated with CO3 Ap using
    simulated body fluid (SBF). Twenty Y-TZP ZrO2 disks with a 12-mm diameter and 1-mm thickness
    were employed as the samples. The disks were divided into two groups which the control group
    without CO3 Ap coating and tested group with CO3 Ap coating. Disks samples are dipped into CO3 Ap
    suspension for one minute and stored in 37°C incubator for 24 hours. The disks were soaked in SBF
    for 1, 4, and 7 day(s) at 36.5°C. The obtained apatite crystals were characterized by scanning electron
    microscopy (SEM). It was found that the apatite formation on the tested group was greater than the
    control group. The EDS pattern showed the presence of Ca and P on the control and tested group after
    SBF soaking, which indicate the apatite deposition on the disks’ surface. However, the Ca and P on
    the tested group was higher compared to the control group. The formation of apatite layer on the
    disks’ surface is bioactivity indicator of CO3 Ap.
