A method for treating surface tissue of a patient includes: providing an electrode having a contact surface, wherein the contact surface has a curved profile; placing the contact surface in contact with surface tissue of the patient; and sliding the contact surface across and in contact with the surface tissue while applying electrosurgical currents to the surface tissue via the contact surface to thereby vaporize and ablate the surface tissue and form a treated band of the surface tissue.

An electrical discharge irrigation device includes a power source to produce power of a first voltage, a circuit coupled to the power source to convert the power of the first voltage to power of a second voltage where the second voltage is higher than the first voltage, a trigger to activate the circuit, an igniter coupled to the circuit to produce a spike, an electrical charge storage component coupled to the igniter the electrical charge storage component becoming conductive and storing an electrical charge after receiving the spike, and an output tip. The output tip includes an electrode and insulating material as an outer layer.

Provided is a method for applying filters for dental CT imaging, including: acquiring the dental CT imaging using a dental CT apparatus; extracting an artifact region from the acquired image; applying a first filter to a region other than the artifact region in the acquired image; and outputting the dental CT imaging to which the filter is applied. Dental CT imaging is provided without an artifact region to assist in medical treatment. More specifically, the dental CT imaging without the artifact region around the metal or tooth is able to be provided to assist in dental treatment. Further, the dental CT imaging without a white artifact region is able to be provided at a boundary portion of field of view (FOV) to assist in dental treatment.

A device for storing and dispensing a flowable dental composition, comprising: a first layer and a second layer, wherein the first layer and second layer form a first chamber for containing a flowable dental composition, a transition zone, and a second chamber; an applicator retained within the second chamber; wherein the first chamber has a first concave surface formed in the first layer and a second concave surface formed in the second layer; wherein the device includes an inactive state and an active state.

The present invention is directed to a debridement and/or implant cleaning tool 1 in which the means for cleaning 4 is made of a biodegradable material. Thus, if parts of the means for cleaning 4 come loose during use, these will be degraded by natural processes in the body and will not remain in the body and cause negative body reactions.
