[The species composition of the dental plaque on the surface of fillings made from different materials].

The present research was aimed at assessment of the quantitative and qualitative composition of oral microflora in cases with different filling material used. Forty-four patients were fitted with 6 types of filling, both traditional and rarely used cliofil (Japan). Soft dental deposit was collected from the surface of fillings for microbiologic investigation. The results permit a conclusion that composites are preferable in comparison with amalgams and cements, the contamination being 8-9 times lower when they are used. Moreover, macrocomposite fillings were associated with streptococcal contamination, in contrast to other materials, when actinomycetes were mainly isolated.
