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.
Claims14
A method of filling a tooth cavity, comprising the steps of:
- (a) identifying the cavity of the tooth to be filled;
- (b) preparing a filling material, comprising portland cement;
- and
- (c) introducing the filling material into the tooth cavity whereby the path of communication between a inner portion of the cavity and the outer surface of the tooth is sealed.
A method of treating tooth decay, comprising the steps of:
- (a) identifying the decay;
- (b) removing the decay to create a cavity to be filled;
- (c) preparing a filling material, comprising portland cement;
- and
- (d) introducing the filling material into the cavity whereby the path of communication between a inner portion of the cavity and the outer surface of the tooth is sealed.
A method of performing root canal therapy on a tooth, comprising the steps of:
- (a) removing a portion of the tooth to expose the root canal;
- (b) preparing the root canal to be filled;
- (c) preparing a first filling material, comprising portland cement;
- (d) introducing the first filling material into the root canal whereby the path of communication between the root canal and the outer surface of the tooth is sealed;
- and
- (e) introducing a second filling material into the cavity remaining after introduction of the first filling material the tooth.
