Abstract:
Objective:To evaluate the dental biofilm penetration efficiency of a novel stabilized stannous-containing sodium fluoride dentifric(EXP) and its lipopolysaccharide (LPS) neutralization efficiency.Methods:A controlled,randomized,examiner-blind in situ clinical trial was conducted with the treatment of PBS(control),EXP and a marketed stannous-containing sodium fluoride dentifrice (MKD).Fluorescent dye,fluorescent probe and fluorescence colocalization were used for sample examination and analysis.Results:EXP offered better stannous penetration into the biofilm than MKD and PBS(P <0.05),as well as greater LPS neutralization efficiency(P <0.05).There was a 96.52% overlap of stannous ions and bounded LPS at the same sites treated by EXP.Conclusion:EXP is more effective than MKD in the delivery of stannous into the biofilm and in the neutralization of LPS.
