In this meta-analysis of randomized controlled trials, supplementation with probiotics in children or adolescents reduced the amount of Streptococcus mutans in saliva but had no effect on other dental health parameters.
What was studied?
The effect of supplementation with probiotics on dental health parameters.
The primary outcomes were the number of dental cavities and salivary counts of Streptococcus mutans and Lactobacilli. The secondary outcomes were other dental health metrics, including plaque severity, gingivitis severity, and salivary pH.
Who was studied?
A total of 1,587 children and adolescents (ages 1–18) without known health conditions.
How was it studied?
A meta-analysis of 19 randomized controlled trials was performed. Eight trials were conducted in India, 4 trials were conducted in Thailand, and 1 trial each was conducted in Australia, Spain, New Zealand, Sweden, Poland, Colombia, and Saudi Arabia.
The probiotics were administered in milk (9 trials), lozenges (5 trials), chewing gum (2 trials), mouth rinse (2 trials), or ice cream (1 trial). In the vast majority of trials, the probiotic strains administered were from the Lactobacillus and/or Bifidobacterium genera. The comparator was a placebo or no treatment. The follow-up duration ranged from 2 months to 9 years.
What were the results?
Supplementation with probiotics reduced the count of salivary Streptococcus mutans (moderate certainty) but had no effect on any of the other outcomes (low or very low certainty).
