[Ultrasonic treatment of the gingiva (experimental research)]

Gingival disease was induced in 18 dogs aged 2-3 years, b.m. 4-6 kg. Gingival grooves of experimental animals (n = 12) were exposed to ultrasound (US) through furacilin solution (1:5000), the gap between needle waveguide and tissues being 1-2 mm. In 6 reference animals the tissues were treated by the routine procedure. Time course of reparative processes was followed up on days 1, 7, 14, 30, and 60 after US session. Experiments have demonstrated the efficacy of low-frequency US in gingival diseases as against the routine treatment: reparative processes normalized on the 7th day after exposure to US.
