Effect of Lactobacillus Rhamnosus GG and Bifidobacterium Longum in Children Aged 3 to 5 Years of Villavicencio and Pasto

2017-03-13 20:23:21 | BioPortfolio


The objective of this study is to determine if the presence of bacterias with probiotic characteristics (Lactobacillus rhamnosus GG and Bifidobacterium longum) in a commercial milk, control some measures that indicate cariogenic processes.


Dental caries is a disease caused by a shift in pH balance, resulting in the formation of a biofilm composed mainly of cariogenic microflora. The interaction between this microflora and host factors conditions the deceleration or acceleration of the disease. Some biotechnology tools have been tried based on all this research, including probiotics, intended for a selective control of the etiological agents of caries and the maintenance of oral homeostasis.

Methodology: In this study, preschool children belonging to public preschool in Villavicencio and Pasto, Colombia will be invited to participate. After obtaining parent´s informed consent, the children will start commercial milk (nanPro3 Nestlé) intake without probiotic during 3 months. One week after, they will start commercial milk with probiotic during others 3 months. Clinical and microbiological testing of saliva at baseline, 3 m and 6m will be performed. Differences in salivary pH (before and after a sugar solution), remineralization and demineralization in early Stage Decay and Established decay tooth (according ICDAS) and quantification of Streptococci of the mutans group. Expected results: Statistically significant decrease in pH drop, demineralization in decay tooth and quantification of Streptococci of the mutans group.

Medical and Biotech [MESH] Definitions

Allergic reaction to milk (usually cow's milk) or milk products. MILK HYPERSENSITIVITY should be differentiated from LACTOSE INTOLERANCE, an intolerance to milk as a result of congenital deficiency of lactase.

Raw and processed or manufactured milk and milk-derived products. These are usually from cows (bovine) but are also from goats, sheep, reindeer, and water buffalo.

The processes of milk secretion by the maternal MAMMARY GLANDS after PARTURITION. The proliferation of the mammary glandular tissue, milk synthesis, and milk expulsion or let down are regulated by the interactions of several hormones including ESTRADIOL; PROGESTERONE; PROLACTIN; and OXYTOCIN.

Expulsion of milk from the mammary alveolar lumen, which is surrounded by a layer of milk-secreting EPITHELIAL CELLS and a network of myoepithelial cells. Contraction of the myoepithelial cells is regulated by neuroendocrine signals.

A rod-shaped bacterium isolated from milk and cheese, dairy products and dairy environments, sour dough, cow dung, silage, and human mouth, human intestinal contents and stools, and the human vagina.
