Middle ear infection affects mostly infants and children, associated with elevated level of S. mutans, which increases the chances of developing caries.
To evaluate the difference in level of Streptococcus mutans between normal children & children affected by middle ear infection.
This descriptive study was carried out on 120 children aged 5 years and younger. They were selected randomly from schools and medical hospitals. S. mutans was counted from saliva sample and a questionnaire was given to be filled by their parents about the feeding method, pattern and specific childhood illness.
Out of 120 children examined, 62 were boys and 58 were girls. Mean CFU in middle ear infection group was 5.60+9.53, whereas in children with no middle ear infection it was 1.70+3.34. Unpaired 't' test revealed statistically significant difference among the two groups (p value = 0.001).
S. mutans count was comparatively higher in children having middle ear infection rather than non-infected children, which may cause dental caries in the future.
中耳感染主要影响婴幼儿和儿童，与变形链球菌水平升高有关，这会增加患龋齿的几率。
评估正常儿童与中耳感染儿童之间变形链球菌水平的差异。
对120名5岁及以下儿童进行了这项描述性研究。他们是从学校和医院随机挑选的。从唾液样本中计数变形链球菌，并向他们的父母发放一份问卷，让他们填写关于喂养方式、模式和特定儿童疾病的信息。
在120名接受检查的儿童中，62名是男孩，58名是女孩。中耳感染组的平均菌落形成单位为5.60+9.53，而无中耳感染的儿童为1.70+3.34。非配对“t”检验显示两组之间存在统计学上的显著差异（p值=0.001）。
中耳感染儿童的变形链球菌计数比未感染儿童相对更高，这可能会在未来导致龋齿。
