Exploring different photodynamic therapy parameters to optimize elimination of Enterococcus faecalis planktonic forms
Effective elimination of microorganisms in infected root canals represents a constant challenge in clinical practice [1 –3]. In chronic endodontic infections the microorganisms are organized in an extracellular polysaccharide matrix forming bacterial biofilms [1,2]. Unlike planktonic forms, in this structuring the elimination of the infectious process requires high doses of drugs or the microorganisms become refrac tory to conventional treatment protocols [2,3]. Despite technological advances in chemomechanical preparation including new instruments and irrigation devices persistent microorganisms in both biofilm and planktonic form are often recovered in root canals after this initial disinfection [4,5].
