Influence of different types of plant extracts on the Streptococcus sobrinus culture

Introduction. Microbiological status of children and
adolescents with the establishment of the prevalence
of certain kinds of microorganisms is the etiological
factor of occurrence and progression of various dental
diseases. Aim of the study. To determine the effect
of different types of plant extracts on the culture of
Streptococcus sobrinus. Materials and methods. The
study examined the effect of plant extracts on the
culture of Streptococcus sobrinus, cultured in the oral
cavity fluid in 146 children aged 3-8 years of different
ethnic groups with varying degree of caries who
resided permanently in biogeochemical conditions
with shortage of fluoride and iodine. Results.
Absence of growth of Str. sobrinus when exposed to
cranberry, red currant, cherry and jostaberry extracts
was demonstrated. Several dilutions of extracts were
studied. No microorganism growth when exposed to
the plum extract in dilutions of 1:1 and 1:2, 1:8, 1:16
was observed; in dilutions of 1:4 and 1:6 significant
growth inhibition was reported when compared
to controls (1±0.15×102, 1±0.1×102; 0; p<0.05).
Conclusions. The most effective plant extracts against
Str. Sobrinus are extracts of cranberry, redcurrant,
cherry and jostaberry in that they can be recommended
in your diet in comprehensive prevention of dental
caries in children as no effective means of endogenous
drug prevention in preschool and primary school age
has so far been introduced.
