Antimicrobial photodynamic therapy (PDT) vs No photodynamic therapy (untreated negative control)

Microbial reduction (viable count, log CFU/mL) · Patients with dental caries (in vivo cariogenic microorganisms, including children with early childhood caries)

In randomized clinical trials, photodynamic therapy significantly reduced cariogenic microbial counts versus untreated control (SMD -1.16, 95% CI -2.02 to -0.30; 2 trials), but heterogeneity was high (I2=70%) and considered too high to rely on; certainty was not graded.

Antimicrobial photodynamic therapy (PDT) vs No photodynamic therapy (untreated negative control)

Microbial reduction (viable count, log CFU/mL) · Cariogenic bacteria (mainly Streptococcus mutans reference strains) and oral biofilms in vitro

In in vitro studies, photodynamic therapy significantly reduced cariogenic microbial counts versus untreated control (SMD -2.64, 95% CI -4.50 to -0.79; 2 studies; I2=0%); certainty was not graded.
