Enhancement of erythrosine-mediated photodynamic therapy of Streptococcus mutans biofilms by light fractionation.
OBJECTIVES We aimed to increase the bacterial cell killing efficacy of erythrosine-mediated photodynamic therapy (PDT) of Streptococcus mutans biofilms by fractionating the delivered light dose into a series of shorter pulses. METHODS S. mutans biofilms of 200 microm thickness were grown in a constant-depth film fermenter (CDFF). Biofilms were incubated with 22 microM erythrosine before being...
متن کاملSusceptibility of Streptococcus mutans biofilms to photodynamic therapy: an in vitro study.
OBJECTIVES The purpose of this study was to evaluate the antimicrobial effect of toluidine blue O (TBO), in combination with either a helium/neon (HeNe) laser or a light-emitting diode (LED), on the viability and architecture of Streptococcus mutans biofilms. METHODS Biofilms were grown on hydroxyapatite discs in a constant depth film fermentor fed with artificial saliva that was supplemented...
متن کاملErythrosine is a potential photosensitizer for the photodynamic therapy of oral plaque biofilms.
OBJECTIVES The purpose of this study was to evaluate the clinical plaque disclosing agent erythrosine as a photosensitizer in the photodynamic killing of the oral bacterium Streptococcus mutans grown as a biofilm. METHODS S. mutans biofilms of 200 microm thickness were grown in a constant-depth film fermenter. In addition to determining localization of the photosensitizer within biofilms usin...
متن کاملAntimicrobial effect of chitosan nanoparticles on streptococcus mutans biofilms.
Nanoparticle complexes were prepared from chitosans of various molecular weights (MW) and degrees of deacetylation (DD). The antimicrobial effect was assessed by the Live/Dead BacLight technique in conjunction with confocal scanning laser microscopy (CSLM) and image analysis. Nanocomplexes prepared from chitosans with high MW showed a low antimicrobial effect (20 to 25% of cells damaged), where...
متن کاملthe effect of antimicrobial photodynamic therapy with radachlorin and toluidine blue on streptococcus mutans: an in vitro study
objectives: dental caries and periodontal diseases are caused by infection of teeth and supporting tissues due to complex aggregate of bacteria known as biofilm, firstly colonized by streptococci. the main purpose of this in vitro study was to evaluate the antimicrobial effects of toluidine blue o (tbo) and radachlorin® in combination with a diode laser on the viability of streptococcus mutans....
