[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.

口腔內(nèi)黑色素沉著按照沉著部位可分為兩大類：牙齦黑色素沉著和牙面黑色素沉著（blacktoothstain，BTS），前者是指因色素在牙齦過度沉積而產(chǎn)生的顏色改變，黑色素的過量生成是其主要原因。（剩余21146字）
