[Abstract]Black tooth stain （BTS）ischaracterizedbybrownish-black bandsalong thegingival margin.Itis typically confinedtothecervicalregionoftheteth.TheetiologyofBTSiscloselylinkedtotheoralmicrobiota，particularlybacteria，such asActinomycesand Porphyromonas.Additionally，te useof probiotics mayrepresenta potential therapeutic approach for BTS.Epidemiological studies have demonstrated a significant corelation between BTSand iron supplement use，iron-richdiets，andiron-containingdrinkingwater，withtheexessiveconsumptionofiron-richfoodsincreasingthe risk of developing BTS.Moreover，anassociation exists between ironstatus and dental caries，with iron deficiencyincreasingsusceptibility tocaries.Onthebasisoftheabove findings，thisreviewaims toprovidedietary guidanceforchildrenwithBTS;explorefuture research directionsconcerningthe microbiota involved in BTS;andexaminethe interrela

tionshipamongBTS，dentalcaries，andiron.Thegoalof thisreview isto propose new strategies for the preventionand managementofBTS and dentalcaries.
