Group A

EXPERIMENTAL

Group A (test group): This group consist of 80 children receiving the probiotic lozenges. The Probiotic lozenges used in the trial is a non-commercial product provided by BioGaia AB, Lund, Sweden. The Probiotic lozenges consist of a minimum of 200 million live L. reuteri (L. reuteri DSM 17938 and L. reuteri ATCC PTA 5289 (L. reuteri Prodentis®). The probiotic lozenge is used twice daily for two months.

Dietary Supplement: (L. reuteri Prodentis®).

Group B

PLACEBO COMPARATOR

Group B (control group): This group consist of 80 children receiving the placebo lozenges. The placebo lozenges used in the trial is non-commercial product provided by BioGaia AB, Lund, Sweden.The placebo lozenges is used twice daily for two months.

Dietary Supplement: Placebo lozenges

Interventions

(L. reuteri Prodentis®).DIETARY_SUPPLEMENT

The Test group is instructed to consume Probiotic lozenges for two months. The counts of salivary mutans streptococci and lactobacilli were evaluated using the CRT test at baseline, one-month, and two- months, from the beginning of the trial for every participating child.
