[Probiotic characteristics of Lactobacilus plantarum HO-69 applied in oral cavity]
Objective:
To investigate the probiotic characteristics of Lactobacillus plantarum (L. plantarum) HO-69 in oral cavity.
Methods:
The adhesion ratios to teeth and dentine surface were determined by in vitro models. Hydrophobicity and surface charges were measured by MATH method. Inhibitory activity was measured by agar well diffusion method.
Results:
The adhesion ratios to hard tissue were quite low. The hydrophobicity and surface charges were high, and it exhibited inhibitory activity against some pathogens.
Conclusion:
The probability is low for L. plantarum HO-69 to initiate or accelerate dental caries. It shows broad-spectrum inhibitory activity and is potential probiotics applied in oral cavity.
