Mutans streptococci present in oral samples at baseline vs Mutans streptococci absent in oral samples at baseline

Development of any (cavitated or non-cavitated) carious lesion · Children younger than 6 years with caries-free primary dentition (no cavitated or non-cavitated lesions at baseline)

Preschool children with mutans streptococci at baseline probably have about four times higher odds of developing early childhood caries (OR 4.13; moderate certainty).
