Abstract
A method of determining an amount of insertion of a probe into a root canal of a tooth using an MRI device. The probe, which is made from magnetic material, is inserted into the root canal, which may be filled with dental pulp. Then, the probe and the root canal are imaged using an MRI device so as to determine the amount of insertion of the probe into the root canal.
Claims5
A method of determining a position of a probe relative to a tooth, comprising the steps of:
- providing the probe, wherein the probe is made from magnetic material;
- coating the tooth with a material detectable by MRI;
- inserting the probe near the tooth;
- and
- imaging the tooth and the probe using an MRI device so as to determine the position of the probe relative to the tooth.
A method of determining a position of a preparing tool relative to a tooth, comprising the steps of:
- providing the preparing tool, which is made from magnetic material and which removes dental pulp from the tooth;
- coating the tooth with a material detectable by MRI;
- inserting the preparing tool near the tooth;
- and
- imaging the tooth and the preparing tool using an MRI device so as to determine a position of the preparing tool relative to the tooth.
A method of determining an amount of insertion of a probe into a root canal of a tooth, comprising the steps of:
- providing the probe, wherein the probe is made from magnetic material;
- coating the root canal with a material detectable by MRI;
- inserting the probe into one of a pulp within the root canal and the root canal of the tooth;
- imaging the root canal and the probe using an MRI device so as to determine the amount of insertion of the probe into the root canal.
