Mutans streptococci, lactobacilli and caries experience in 12‐year‐old Icelandic urban children, 1984 and 1991
Abstract In order to evaluate changes in salivary counts of cariogenic bacteria and relate these to trends in caries experience, stimulated saliva was collected from a 20% random sample of 12‐yr‐old residents of Reykjavik. Iceland (252 children) in 1991 under conditions consistent with those of a su...
