Bacterial colonization of infants' oral cavities is a key factor for future caries risk. This study sought to longitudinally assess oral bacterial colonization in a group of predentate infants in relation to some mother and infant factors.
A total of 50 mother-infant pairs were enrolled. When infants were 3-month-old, data were collected about some infant and mother factors; additionally, maternal Decayed, Missing, and Filled Teeth (DMFT) scores and salivary samples of mothers and infants were obtained. At 6 months of infant's age, another infants' salivary samples were obtained. Saliva was cultured to detect and quantify () and ().
() was detected in all infants at 3 months. 74 and 96% of infants acquired at 3 and 6 months, respectively. detection was significantly higher with higher maternal DMFT scores, salivary counts, and lower counts, as well as when infants were given sugar-containing complementary foods/drinks. At 3-6 months, infants' counts were significantly positively correlated with maternal counts and DMFT scores and negatively correlated with maternal counts. The opposite was evident for infants' counts. Regression analysis showed that increased maternal DMFT scores and counts, and Cesarean delivery were strong predictors for increased infant's counts. While increased DMFT scores and maternal counts were strong predictors for reduced infant's counts.
Poor maternal oral health, early introduction of sugars in the diet, and probably Cesarean delivery can negatively impact infants' oral bacterial colonization and possibly future caries risk.
Understanding factors associated with oral colonization of both caries-producing and protective flora in infants of different populations is important for caries prevention. This, in turn, can aid tailoring oral health promotion programs for expectant mothers.

婴儿口腔细菌定植是未来患龋风险的关键因素。本研究旨在纵向评估一组无牙婴儿的口腔细菌定植情况，并分析其与一些母婴因素的关系。
共纳入50对母婴。婴儿3个月大时，收集有关婴儿和母亲的一些因素的数据；此外，获取母亲的龋失补牙面（DMFT）评分以及母亲和婴儿的唾液样本。婴儿6个月大时，再次采集婴儿的唾液样本。对唾液进行培养，以检测和定量（）和（）。
3个月大时，所有婴儿均检测到（）。3个月和6个月时，分别有74%和96%的婴儿感染了（）。母亲DMFT评分较高、唾液（）计数较高、（）计数较低以及婴儿食用含糖辅食/饮料时，（）检测率显著更高。3至6个月时，婴儿的（）计数与母亲的（）计数和DMFT评分显著正相关，与母亲的（）计数负相关。婴儿的（）计数情况则相反。回归分析表明，母亲DMFT评分增加、（）计数增加以及剖宫产是婴儿（）计数增加的有力预测因素。而DMFT评分增加和母亲（）计数增加是婴儿（）计数减少的有力预测因素。
母亲口腔健康状况不佳、饮食中过早引入糖分以及剖宫产可能会对婴儿口腔细菌定植产生负面影响，并可能增加未来患龋风险。
了解不同人群婴儿中致龋菌和有益菌口腔定植的相关因素对于预防龋齿很重要。这反过来有助于为孕妇量身定制口腔健康促进计划。
