<i>Streptococcus dentisani</i> as an oral probiotic: a systematic review of clinical evidence on the pH modulation and microbiota shifts

<i>S. dentisani</i> demonstrates consistent mechanistic benefits-pH increase and modulation of the oral microbiota-supporting its candidacy as an oral probiotic. Evidence on caries prevention remains insufficient, underscoring the need for longer, standardized trials incorporating clinical endpoints and microbiological profiling.
