“…Although there are limited reports of positive effects for caries prevention and insufficient safety studies, probiotics significantly increased the chance of reducing S. mutans [Gruner et al, 2016], and mutans streptococci are major pathogens of dental caries [Takahashi and Nyvad, 2011], which makes probiotic use in caries prevention a hot topic. Accordingly, the inhibitory activity of probiotics against common oral pathogens (S. mutans, Candida albicans, S. sanguinis) has also been tested in vitro [Soderling et al, 2011;Jiang et al, 2015;Wu et al, 2015;Jiang et al, 2016], and its fermentation profiles have been the subject of studies [Hedberg et al, 2008;Douillard et al, 2013].…”
