In vitro lethal photosensitization of S. mutans using methylene blue and toluidine blue O as photosensitizers.

Photodynamic inactivation effect of methylene blue and toluidine blue O on ATCC Escherichia coli and clinical isolate of multidrug-resistant Escherichia coli

Antifungal effects of low level laser on Candida species with using Methylene blue and toluidine blue dayes

Introduction: Oral Candidiasis is the most common lesion in Immuno compromised patients. Using antifungal drugs are routine treatment for this condition. The aim of this study was incorporating photodynamic therapy with low level laser (685 nm), in presence of 2 dyes (methylene blue and tolidine blue), as a photosensitizer on C. albilcans, C. glabrata. C. krusie and C.tropicalis. Methods...

The susceptibility of Streptococcus mutans to antibacterial photodynamic therapy: a comparison of two different photosensitizers and light sources

UNLABELLED Streptococcus mutans is the main etiological agent for dental caries. Recently, photodynamic therapy (PDT) has been introduced as a new modality in bacterial decontamination. OBJECTIVE This in vitro study was carried out to evaluate the susceptibility of Streptococcus mutans to antibacterial PDT using two different photosensitizers and light sources. MATERIAL AND METHODS Standard...

The 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. ...

In vivo killing of Porphyromonas gingivalis by toluidine blue-mediated photosensitization in an animal model.

Porphyromonas gingivalis is one of the major causative organisms of periodontitis and has been shown to be susceptible to toluidine blue-mediated photosensitization in vitro. The aims of the present study were to determine whether this technique could be used to kill the organism in the oral cavities of rats and whether this would result in a reduction in the alveolar bone loss characteristic o...
