Streptococcus dentisani and Streptococcus mutans in dental biofilm of preschoolers with and without early childhood caries: a cross-sectional study

Key Points

• Dental biofilm analysis reveals a significant presence of streptococcus mutans among kids with early childhood caries.
• Streptococcus dentisani shows a contrasting abundance in children without early childhood caries, indicating a potential protective role.
• Cross-sectional study involved comparing dental biofilm samples from preschoolers with and without early childhood caries to assess microbial diversity.
• Findings support the idea that varying levels of specific streptococcus species may influence the development of early childhood caries.
