Abstract

Bacterial lipopolysaccharide (LPS) plays a major role in the development of periapical bone resorption. IL-1 and $TNF-{\alpha}$ are known to stimulate bone resorption and inhibit bone formation. Recent evidence has indicated that polymorphonuclear leukocytes (PMNs) have the ability to release IL-1 and $TNF-{\alpha}$ Calcium hydroxide is an effective medicament in root canal infections, reducing the microbial titre within the canal. It has been proposed that the therapeutic effect of $Ca(OH)_2$ may also be the result of direct inactivation of LPS.(omitted)
