| trends in dental health among icelandic urban children. | caries experience, oral hygiene and caries-related salivary parameters were recorded in a 20% representative sample of 12-year-old schoolchildren in reykjavik, iceland in 1991. the majority of the children was re-examined 3 years later in 1994. trends in prevalence of caries and salivary bacteria were assessed by comparison with an analogous earlier longitudinal study (1984-87). mean dfs values for 12-year-olds were 12.1 and 4.1, for 15-year-olds 23.3 and 11.3 in the earlier and later study, res ... | 1997 | 9249184 |
| mutans streptococci, lactobacilli and caries experience in 12-year-old icelandic urban children, 1984 and 1991. | 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 survey conducted in 1984. the mean and median counts of salivary mutans streptococci and lactobacilli remained similar in the two studies. however, the frequency distribution at lower levels of mutans streptococ ... | 1995 | 7781301 |
| prevalence of streptococcus sobrinus in relation to dental caries in children from iceland and the netherlands. | the aim of this study was to investigate the presence of s. sobrinus and s. mutans in specimens of dental plaque and saliva of children five years of age in reykjavik, iceland (study 1) and in samples of dental plaque from children nine years of age in amsterdam, the netherlands (study 2). the immuneblotting technique (ibt) was a suitable method to evaluate the presence and numbers of s. mutans and s. sobrinus in human dental plaque and saliva. in study 1, eighty-four children were evaluated bac ... | 1990 | 2212191 |
| dental caries and cariogenic factors in pre-school urban icelandic children. | caries prevalence and several caries-related factors were measured in 158 pre-school children in reykjavík, initially aged 4 years and followed longitudinally for 2 years. the mean dmfs at 4 years was 3.3 and rose to 5.8 at 6 years although 34% remained caries-free throughout the study. caries was very unevenly distributed. children with dmfs > or = 5 at 4 years were significantly more likely to have caries in their permanent dentition at 6 years than those with a lower caries score at 4 years. ... | 1993 | 8242682 |
