Experimental evaluation of the galvanophoretic dentin nanoimpregnation for recurrent caries prevention

Aim to study the dentine galvanophoretic impregnation with nanoparticles of coppercalcium hydroxide (CCH) in teeth carious cavities.
 Material and methods. The was conducted on 21 removed for various medical indications, a concomitant diagnosis "dental caries". After mechanical treatment, cavities were washed saline solution, then CCH paste placed cavity floor, covered aluminum foil, drained isolated temporary fillings. To maintain osmotic balance, laboratory model: plastic bath solution melamine sponge, period 1, 14 30 days. Then longitudinal sections prepared electron microscopic examination.
 Results. During galvanophoresis, copper area floor occurred already during first day procedure. penetration depth reached 10.1 microns. maximum particles into dentin (up microns) detected after 30-days-galvanophoresis. values diffusion coefficient its velocity recorded day. With an increase time galvanophoresis days, these indicators decreased.
 Conclusion. described method may be used as option choice prevention recurrent dental caries, especially presence deep cavities.
