    Abstract: A root canal treatment instrument 100 continues drive of a cutting tool 5 in forward rotation drive until reaching 180 degrees, and when a load applied to the cutting tool 5 is equal to or greater than a reference load, drive of the cutting tool 5 is switched to reverse rotation drive until reaching 90 degrees. In the root canal treatment instrument 100, when a cumulative amount of rotation is equal to or greater than a reference amount of rotation, change to a drive pattern is made, forward rotation drive is continued until reaching 90 degrees, and when a load applied to the cutting tool 5 is equal to or greater than the reference load, drive of the cutting tool 5 is switched to reverse rotation drive until reaching 180 degrees.

    Abstract: A dental handpiece is a dental handpiece configured to detachably hold a cutting tool. The dental handpiece includes: a holding portion provided with an insertion port into which the cutting tool is insertable, the holding portion being configured to hold the cutting tool inserted in the insertion port; and a main body portion configured to accommodate the holding portion, the main body portion being provided with a water introduction hole and a plurality of chip air holes. The plurality of chip air holes are disposed to sandwich the water introduction hole in a second direction, the second direction intersecting a first direction in which the insertion port and the water introduction hole are arranged.

    Abstract: A data processing apparatus includes: an input portion configured to receive IOS data and CT data as an input, the IOS data being obtained by performing scanning by an intra oral scanner and including coordinate data of a point group indicating a surface shape of a tooth row including an IOS crown and an IOS gingiva, the CT data being obtained by performing capturing by a CT imaging device and including volume data of a CT crown; and processing circuitry. The processing circuitry replaces, in the CT data, a crown part of a CT tooth included in the CT data with which a shape of the IOS crown matches, with the IOS crown included in the IOS data, and performs synthesis in such a way that the IOS gingiva is arranged near the IOS crown after replacement.

    Abstract: A data processing apparatus that includes an input interface to which three-dimensional data including position information of each point of a point group indicating a surface of at least one object is input; and processing circuitry that is configured to process the three-dimensional data that is input from the input interface. The processing circuitry is configured to process two-dimensional data from the three-dimensional data, identify a predetermined object among the at least one object based on the two-dimensional data, and extract predetermined three-dimensional data including the position information of each point of a point group indicating a surface of the predetermined object that is identified.
