Early childhood caries has been characterized as first affecting the primary maxillary anterior teeth, followed by the involvement of the primary molars. Other terms for dental caries in preschool children, which inappropriately may imply cause for the disease, includes baby bottle tooth decay, nursing caries, milk bottle syndrome, baby bottle caries, nursing bottle mouth and nursing mouth.
To explore the relationships of feeding practices, age and number of teeth present with mutans streptococci colonization in infants.
A comparative clinical study conducted on 160 children aged from 6 to 30 months in the Department of Pedodontics and Preventive Dentistry, Bapuji Dental College and Hospital in collaboration with Child Health Institute and Research Center and Department of Oral Pathology and Microbiology, Bapuji Dental College and Hospital, Davangere.
Baseline data collection included: (i) Parents of the infants were asked open ended questions about the baby feeding practices, (ii) The age of the subjects were obtained from the immunization register maintained at Child Health Institute and Research Center and were grouped into group I (6-11 months), group II (12-17 months), group III (18-23 months) and group IV (24-30 months), (iii) Clinical examination of children was done by using mouth mirror and explorer in flash light.(6) For each child number and location of erupted teeth was recorded, (iv) Microbial screening for mutans streptococci involved sampling of saliva from each child was performed by placing a sterile wooden tongue blade on the dorsum of the tongue and the number of colony forming units (CFU) were recorded.
According to feeding practices, 34 children were in breastfed category, 39 were in baby bottle category and 87 children reported no bottle usage. Out of 160 children examined, a total 142 children were colonized with mutans streptococci. 18 children were found to be colonized with low colony forming units, 78 children were found to be colonized with moderate colony forming units and 64 children were colonized with high colony forming units. In baby bottle group, all of 39 subjects were reported to have sweetened milk, sugar in the bottle.
Among different feeding practices, all the three subgroups viz breastfed children, children with nursing bottle usage and children with no bottle usage, all have shown mutans streptococci acquisition. But breastfed children have shown least number of high colony forming units, which is increased in the case of children using nursing bottle and is maximum in the children who were neither breastfed nor fed with nursing bottle. Percentage of children colonized with mutans streptococci increases with age and as the number of teeth increase, number of colony forming units were also found to be increasing.

幼儿龋齿的特点是首先影响上颌乳前牙，随后累及乳磨牙。学龄前儿童龋齿的其他术语，可能不恰当地暗示了该病的病因，包括奶瓶龋、哺乳龋、奶瓶综合征、奶瓶龋、奶瓶口和哺乳口。
探讨喂养方式、年龄和出牙数与婴儿变形链球菌定植之间的关系。
在巴普吉牙科学院和医院儿童健康研究所与研究中心以及巴普吉牙科学院和医院口腔病理与微生物学系的合作下，对160名6至30个月大的儿童进行了一项比较临床研究。
基线数据收集包括：（i）询问婴儿父母关于婴儿喂养方式的开放式问题；（ii）从儿童健康研究所和研究中心保存的免疫登记册中获取受试者的年龄，并将其分为第一组（6至11个月）、第二组（12至17个月）、第三组（18至23个月）和第四组（24至30个月）；（iii）在手电筒照明下使用口镜和探针对儿童进行临床检查。记录每个儿童已萌出牙的数量和位置；（iv）对变形链球菌进行微生物筛查，通过将无菌木舌板放在舌背上从每个儿童采集唾液样本，并记录菌落形成单位（CFU）的数量。
根据喂养方式，34名儿童为母乳喂养组，39名儿童为奶瓶喂养组，87名儿童报告未使用奶瓶。在160名接受检查的儿童中，共有142名儿童被变形链球菌定植。发现18名儿童定植的菌落形成单位较低，78名儿童定植的菌落形成单位中等，64名儿童定植的菌落形成单位较高。在奶瓶喂养组中，39名受试者均报告奶瓶中有加糖牛奶、糖。
在不同的喂养方式中，母乳喂养儿童、使用奶瓶喂养儿童和未使用奶瓶喂养儿童这三个亚组均显示有变形链球菌感染。但母乳喂养儿童中高菌落形成单位的数量最少，使用奶瓶喂养的儿童数量增加，既未母乳喂养也未使用奶瓶喂养的儿童数量最多。变形链球菌定植儿童的百分比随年龄增长而增加，并且随着出牙数的增加，菌落形成单位的数量也在增加。如何引用本文：夏尔马R，普拉巴卡尔AR，高尔A。6至30个月大儿童变形链球菌定植与喂养方式、年龄和出牙数的关系：一项体内研究。《国际临床儿科牙科学杂志》2012；5（2）：124 - 131。
