| Popis: | Introduction: Streptococcus mutans (S. mutans) is the major pathogen involved in caries development which is the most common childhood infection. Lactobacilli and Bifidobacteria are commonly used as probiotics and are added to fermented food such as yoghurt, and have been linked to reducing caries risk in children. Objectives: to investigate the effect of probiotic-containing yogurt on salivary levels of S. mutans, gingival inflammation and plaque accumulation in children and to evaluate the possible inhibitory effect of two probiotic bacterial strains (Lactobacillus rhamnosus and Bifidobacterium animalis) against S. mutans invitro. Methodology: This study was performed with 30 children; who were given yohgurt containing probiotic (group 1) or control yoghurt (group 2) daily for a period of 6 weeks; Sreptococcal mutans count, gingival index (GI) and plaque index (PI) were assessed throughout the 6 weeks of intervention and 2 weeks post-intervention. Lactobacillus rhamnosus and Bifidobacterium animalis were tested against S. mutans invitro. Results: There was a statistically significant decrease (p |
