This study investigated the effect of antimicrobial photodynamic therapy (aPDT) over Streptococcus mutans biofilm.

Materials and methods

Eighteen (n = 18) patients were selected and one palatine device with dental blocks was used. The biofilm was treated by curcumin and Photogem® with a LED and the effect was analyzed by CFU/ml.


Although, statistical analysis showed significant reductions for aPDT mainly with Photogem® (p = 0.02), these were low.


The results suggest a low antimicrobial effect of aPDT over S. mutans biofilm. Some parameters used need to be improved.

Clinical Significance

This technique can be a promising in Dentistry.
