Abstract
Introduction
An experimental Portland cement was manufactured with pure raw materials under controlled
laboratory conditions. The aim of this study was to compare the chemical constitution,
physical properties, and biocompatibility of experimentally manufactured Portland
cement with those of mineral trioxide aggregate (MTA) and Portland cement.
Methods
The composition of the cements was determined by scanning electron microscopy (SEM)
and energy-dispersive x-ray analysis (EDAX). The setting time and compressive strength
were tested. The biocompatibility was evaluated by using SEM and XTT assay.
Results
SEM and EDAX revealed the experimental Portland cement to have a similar composition
to Portland cement. The setting time of the experimental Portland cement was significantly
shorter than that of MTA and Portland cement. The compressive strength of the experimental
Portland cement was lower than that of MTA and Portland cement. The experimental Portland
cement showed a similar biocompatibility to MTA.
Conclusions
The experimental Portland cement might be considered as a possible substitute for
MTA in clinical usage after further testing.
