Evaluation of photodynamic therapy using a diode laser 635 nm as an adjunct to conventional chemo-mechanical edodontic procedures against enterococcus faecalis biofilm: ex-vivo study
The study aimed to evaluate the antimicrobial effect of photodynamic therapy (PDT) with the use of Toluidine Blue (TB) on extracted teeth infected with biofilms of Enterococcus faecalis. Fifty-four extracted teeth with single-roots and single canals were mechanically shaped, autoclaved, and contaminated with E. faecalis.
