Embodiments of the present disclosure provide a sculpting and shaping tool for dental resin, comprising: a handle, a rotating assembly, and a sculpting and shaping tip. One end of the sculpting and shaping tip is coaxially and rotatably connected to one end of the handle through the rotating assembly. When in use, after a resin restorative material is filled in a carious cavity, the sculpting and shaping tip is placed on the resin restorative material. The handle moves to drive the sculpting and shaping tip to rotate, thereby rolling a surface of the resin restorative material. After rolling, the surface of the resin restorative material is smoother and free of protrusions, effectively preventing unevenness on the surface.

The present invention provides a paste syringe that is designed to release, as much as possible, internal pressure generated inside a syringe body when a paste is subjected to pressure, thereby avoiding paste solidification or liquid seepage due to residual pressure, and accordingly avoiding difficulty in forward movement of an extrusion member. The paste syringe includes a syringe body, a nut member, a screw member, an extrusion member, and a closure member. The syringe body has a cylindrical inner periphery and includes a main section in which a paste is stored. The nut member is located at a base end of the main section of the syringe body such that the nut member and the main section are concentric, and has a cylindrical inner periphery on which a female thread is formed. The screw member includes a male thread section with a male thread formed on its cylindrical outer periphery, and an operation section located at the rear of the male thread section, and is allowed to move forward within the main section of the syringe body while being rotated in a direction of forward movement with the male thread being screwed into the female thread of the nut member. The extrusion member is located at a tip of the screw member. The closure member is detachably attached to a tip part of the syringe body to close a discharge orifice of the syringe body. The extrusion member includes a disc-shaped portion with an outer diameter corresponding to an inner diameter of the main section of the syringe body, and has a residual pressure-release space is provided behind the disc-shaped portion, and the disc-shaped portion includes at least one through hole that communicates with the residual pressure-release space.
