Streptococcus mutans and Streptococcus sobrinus colonization and caries experience in 3- and 5-year-old Thai children.

Objectives: The aim of this study was to examine the colonization of Streptococcus mutans and Streptococcus sobrinus in supra-gingival plaque samples and to determine their correlation with the prevalence of early childhood caries (ECC) in Thai children.

Materials And Methods: A total of 344 Thai children, ages 3 and 5 years, were invited to participate in this study. Caries status of the children was examined.

Mode of delivery, mutans streptococci colonization, and early childhood caries in three- to five-year-old Thai children.

Objective: To investigate whether mode of delivery is associated with mutans streptococci (MS) colonization and early childhood caries (ECC) in preschool Thai children.

Methods: Three hundred and fifty mothers and their 3- to 5-year-old children (184 born vaginally and 166 born by Caesarean section) participated in the study. Data included a dental examination, MS colonization assessed by the Dentocult(®) SM Strip Mutans method, and a questionnaire survey of family socio-demographic information, as well as children's birth history, dietary habits, and oral health practices.
