The effect of sublethal photodynamic therapy on the expression of Enterococcal surface protein (esp) encoding gene in Enterococcus faecalis: Quantitative real-time PCR assessment.

Background: During antimicrobial photodynamic therapy (aPDT) in the treatment of endodontic intracanal infection, it is extremely likely that microorganisms would be exposed to sub-lethal doses of PDT (sPDT). Although sPDT would not result in microorganism death, it can considerably influence microbial virulence. This study evaluated the effect of sPDT on gene expression of Enterococci surface protein (esp) as a major virulence factor for biofilm formation in Enterococcus faecalis.

Background: Evidence on the protecting effect of laser on bleached enamel is scarce and controversial. Therefore, we aimed to test for the first time whether different wavelengths of diode laser (810 and 980 nm) can prevent enamel surface corrosion. We also tested for the first time whether such therapeutic effects of laser are limited to specific "laser-activated" bleaching gels or both conventional and laser-activated gels.
