The dental handpiece comprises a handle 1 and a housing 2 with a socket for the spherical head 3 mounted therein to provide a full spatial rotation, i.e. rotation in either direction along the spherical surface of the housing 2. The head 3 and the turbine 4 arranged collet holder 5 with the pusher 6 and a dental tool (boron) 7. The housing 2 has an opening for supplying gas to the turbine 4, and a working gas channel 8 communication with the gas supply manifold. Switching mechanism for locking and releasing dental instrument 7 is designed as a rotary cam 9 with simply supported on the hollow end 10 of the pusher 6 collet holder 5 profiled surface 11. Preferably, the cam 9 is formed as a cylindrical shaft with a rotary crescent groove, which is adapted to form a cam surface 11 consisting of several coupled together smoothly curved surface portions and two angled to each other plane portions. The cross section of the surface 11 consists of a conjugate between a smooth arcs and two straight lines associated with each other at an obtuse angle. The pusher 6 collet holder 5 is formed as a hollow truncated cone and a cylindrical portion with a common non-through axial channel. The eccentric 9 is provided with a rotation limiter in the form of a cylindrical rib 12 and is formed with hexagonal head 13. At the optical head 3 is mounted a radiation source in the form of at least one LED 22, connected to a source of electrical power, wherein it is provided with a small-sized video camera 23, fastened on the outer side of the head 3 and connected to the visual display means and to a source of electrical power via a cable 24. in this improved fitness function associated with that LIGHT ennaya surface becomes accessible to the greatest extent for objective visual inspection during operation in real time. As a result, significantly improved the quality of treatment and reduces the duration of the intervention and treatment of tooth breaks.Стоматологический наконечник содержит ручку
