Dental diseases in children, such as carious lesions of deciduous teeth, traumatic injuries of the oral cavity occupy one of the first places among chronic diseases.

Separate use of techniques such as infrared radiation - a spectrum of electromagnetic waves, laser treatment, ultraviolet rays for traumatic injuries of the oral cavity did not always give the expected effect. The study of the effect of the apparatus of magnetic-infrared-laser therapy (MIL-T) “Sogdiana” in children with traumatic injuries of the oral cavity, was more effective than traditional therapy.
