A prospective longitudinal cohort study of the effectiveness of 25% xylitol toothpaste on mutans streptococci in high caries-risk young children.

Aim: To compare the prevalence of mutans streptococci (SM) prevalence and categorical distribution in the saliva of high caries-risk children after their 24 months exposure to 25% xylitol toothpaste applied twice a day. To also examine the early caries susceptibility at baseline.

Background: An observational design with two times of collection.

Streptococcus Mutans Infections in Infants and Related Maternal/Child Factors.

Objective: The aim of the study was to investigate the maternal-child infection, mutual interaction and potential risk factors altering this interaction.

Material And Methods: A total of 160 mothers who were paired with their children were recruited. Saliva from mothers and children was collected and categorized levels were analyzed.

Effectiveness of fluoride varnish four times a year in preventing caries in the primary dentition: A 2 year randomized controlled trial.

Objectives: To test the effectiveness of fluoride varnish in preventing caries in early childhood in children at high risk of caries.

Basic Research Design: Randomized controlled trial.

Participants: 504 participants, with mean age of 21 months at baseline randomly allocated into a test and a control group.

Association between salivary level of infection with Streptococcus mutans/Lactobacilli and caries-risk factors in mothers.

Aim: Understanding factors in mothers associated with high and low salivary levels of Streptococcus mutans and Lactobacilli is an important strategy for early childhood caries prevention. Aim of the study was to identify the association between salivary levels of Streptococcus mutans/Lactobacillus and potential caries risk factors in mothers.

Materials And Methods: Cross-sectional design used a voluntary sample of 300 mothers of young children.
