Chemistry and Bioactivity of NeoMTA Plus™ versus MTA Angelus® Root Repair Materials

Figure 1

FTIR spectra of (a) original components of MTA Angelus and NeoMTA Plus; completely versus initially set MTA Angelus (b) and NeoMTA Plus (c); deconvoluted spectra of completely set materials that were incubated for 15 days in PBS (d). Crystallinity was calculated by (a + b)/c (e). CO₃/PO₄ ratio was calculated by dividing the area under v₃CO₃ by area under v1v3PO₄ (f).
