The comparison of physicochemical and bioactivity properties of different nanoparticles modified calcium silicate-based cement.

ABSTRACT:

Background

To investigate the effects of adding ZrO₂, TiO₂, and two sizes of hydroxyapatite (HAP) nanoparticles on the physicochemical and bioactivity properties of calcium silicate-based cement (CSC).

Methods

MTA, PC, and nanoparticle-modified groups (5% and 10% n-ZrO₂, n-TiO₂, n-HAP1, n-HAP2) were evaluated for setting time, compressive strength (1, 7, 14 days), solubility (14 days), and bioactivity. Setting time and compressive strength followed ISO 9917-1:2007, solubility followed a modified ISO 6876:2012, and bioactivity was analyzed using SEM-EDS.

Results

All groups showed significantly reduced setting times (p < 0.001) compared to MTA and PC, with 10% n-HAP1 showing the greatest reduction. Compressive strength increased over time in all groups except 5% and 10%
