Effect of antimicrobial photodynamic therapy on microleakage of class cavities restored with composite resin

Cariogenic bacteria are responsible for development of dental caries. They ferment the carbohydrates adhered to dental surfaces and produce acids, which cause demineralization and lead to development of carious lesions. Streptococcus mutans (S. mutans) and Lactobacillus acidophilus are commonly isolated from dental biofilms. Dental caries may be prevented by decreasing the count of these bacteria [1]. Chemical agents such as chlorhexidine and ethylenediaminetetraacetic acid are used to eliminate bacteria following cavity preparation or root canal instrumentation in order to prevent microbial reinfection [2].
