Abstract

Mineral Trioxide Aggregates (MTA) was recently developed at Loma Linda University. It has been shown to possess good sealing ability when tested with dye, bacteria, and a fluid filtration technique.

Endotoxin is a component of the cell wall of Gram negative bacteria. It has been proposed that it may play a role in the pathogenesis of periradicular lesions. Previous studies have demonstrated that MTA can prevent the leakage of bacteria. However, the bacterial products were not tested during these studies.

This study used endotoxin to compare the sealing ability of SuperEBA, IRM, amalgam, and MTA.

The results showed that MTA permitted less leakage than IRM and amalgam at 1, 2, 6, and 12 weeks (p < 0.05), and leaked less endotoxin than SuperEBA at 2 and 12 weeks (p < 0.05)
