OBJECTIVE
The age at which a child becomes colonized with mutans streptococci (MS) is important for understanding early childhood caries. The aim of this study was to explore the relationship of age with MS colonization in infants.
METHODS
Inner-city children (n = 149) between the ages of 8 months and 15 months, inclusive, who reportedly were still using a baby bottle, were sampled for MS.
RESULTS
Evidence of MS colonization was seen as early at 10 months of age. For children 12 months old or younger (n = 80), 25 percent had detectable levels of MS; in the 15-month age group, 60 percent were colonized.
CONCLUSION
This study suggests that prevention of MS colonization in some populations may need to be initiated prior to the child's first birthday.
目的
了解儿童变形链球菌（MS）定植的年龄对于理解幼儿龋齿至关重要。本研究的目的是探讨年龄与婴儿MS定植之间的关系。
方法
选取年龄在8个月至15个月（含）之间、据报道仍在使用奶瓶的市中心儿童（n = 149）进行MS采样。
结果
在10个月大时就已发现MS定植的迹象。对于12个月及以下的儿童（n = 80），25%的儿童MS水平可检测到；在15个月龄组中，60%的儿童被定植。
结论
本研究表明，在某些人群中，预防MS定植可能需要在儿童一岁生日之前就开始。
