Evaluating the Effect of Enviromental Factors and Early Childhood Caries on Salivary Streptococcus Mutans Count in 3-5 Year Old Children in Yazd
Introduction: Early childhood caries (ECC) is one of the most common problems in children worldwide which is seen in 3-45% preschool children population. Bacterial factor is one of the main four components (time, microorganism, diet, host) to create caries. Streptococcus mutans is one of the most im...

Bacterial factor is one of the main four components (time, microorganism, diet, host) to create caries. Streptococcus mutans is one of the most important cariogenic microorganisms. The objective of this study is evaluating Streptococcus mutans count in children with ECC and caries free children considering other factors. The aim of this study was to find the CFU of Streptococcus mutans in saliva of children with ECC versus caries free ones. In addition environmental factors affecting CFU of this micro organism. Methods: Salivary Streptococcus mutans count in 76 3-5 year old children was done in two groups (ECC and caries free). Non stimulated saliva was collected and cultured on Streptococcus mutans specific growth medium. Data was analyzed with Chi-Square, spearman, Kruskal–Wallis,Mann–Whitney tests. Results: Differences in colony count in study groups were statistically significant and was less in caries free children (p value<0.001). Colony count had no relationship with age, sex, weight, Body Mass Index(BMI) and parents educational level but sugar consumption frequency, feeding method (breast or bottle) and night time breast feeding had significant effect on colony count (p value=0.019). Conclusion: In the current study, a statistically significant difference was seen in colony count in two groups. Sugar consumption frequency and feeding method had a significant impact on colony count. Micro organisms are still the most important factors in creating caries but feeding pattern and sugar consumption frequency also have an important role. The results also showed that parents educational level does not influence reducing caries which should be noted.http://tbj.ssu.ac.ir/browse.php?a_code=A-10-1366-1&slc_lang=en&sid=1caries Streptococcus mutans preschool age colony count. |
