Milk-based probiotic vs placebo or control

Plaque index (PI) / oral hygiene · Children and/or adolescents (<18 years) without background systemic disease

In a subgroup analysis, milk-based probiotics reduced the bacterial plaque index more than other presentations (MD -0.10, 95%CI -0.20 to -0.00; p-interaction=0.01); not GRADE-rated.

Probiotics vs placebo or control

Plaque index (PI) / oral hygiene · Children and/or adolescents (<18 years) without background systemic disease

Probiotics may make little to no difference to the bacterial plaque index versus control (MD 0.21, 95%CI -0.55 to 0.96; very low certainty).
