Introduction/Objective. Contemporary tendencies suggest that probiotics can
significantly reduce the prevalence of caries in children, so it can be
considered that they have a positive effect on general and oral health.
Lactobacillus rhamnosus GG (LGG) is a probiotic culture of particular
importance in preventive dentistry. The aim was to assess the effects of
consumption of probiotic strain Lactobacillus rhamnosus GG on the dental
plaque accumulation in children with mixed dentition. Methods. Research
included 90 children with mixed dentition (5-12 years old). First study
group consumed 200 ml of Lactobacillus rhamnosus GG-enriched yogurt (B-Activ
LGG, Dukat) daily for a period of 14 days, while the remaining 30 formed the
second study group who consumed 200 ml of yogurt (Jogurt 1,5% milk fat,
Imlek) with manually added powder from probiotic capsule (Wayaforte LGG
capsule, Medis) daily for14 days. The control group consisted of 30 children
who had regular diet during examination period. Silness-L?e plaque index and
saliva pH (pH-Fix-0-14, Macherey-Nagel) were determined at baseline and also
upon intervention completion. Results. An increase in pH values was
observed in both study groups. In general sample, there is a significant
decrease of mean plaque index values (p ? 0.001). Both study groups had
significant decrease of mean plaque index values on the baseline and after
14 days consumption of yogurt. In the control group the number of subjects
with decrease plaque index values did not correlate and no association was
found. Conclusion. Consistent consumption of LGG culture-enriched yogurt
inhibits dental film accumulation and promotes saliva pH increase in
children with mixed dentition.
