XRD profiles of pleromin and osteodentin. (a1) Powder XRD profile of pleromin. (a2) XRD peaks for β-TCP (JCPDS 09-0169). Micro-beam X-ray photographs of (b) immature pleromin, (c) mature pleromin, and (d) osteodentin. Note that the Debye–Scherrer rings indicate that crystallites in pleromin (b, c) and in osteodentin (d) have no preferred orientation. (e) Densitometric traces of (b–d). *Indicates peak other than β-TCP.
