Abstract
An improved method for filing and sealing tooth cavities involves the use of a cement composition which exhibits several advantages over existing orthograde and retrograde filling materials, including the ability to set in an aqueous environment. In a preferred embodiment, the cement composition comprises Portland cement, or variations in the composition of such cement, which exhibit favorable physical attributes sufficient to form an effective seal against re-entrance of infectious organisms.
