| efficacy of a dip slide test for mutans streptococci in caries risk assessment. | the aim of this study was to evaluate the efficacy of a dip slide test for mutans streptococci in caries risk assessment, when the microbiological results were compared to well-defined clinical criteria (dcc) for caries risk, clinically measured through high and low caries activity. eighty-one volunteers from the 6th to 8th grades from public schools of piracicaba, são paulo, brazil, were evaluated for dental caries. all free smooth surfaces were evaluated to check whether or not there were whit ... | 2001 | 11784287 |
| association between caries prevalence and clinical, microbiological and dietary variables in 1.0 to 2.5-year-old brazilian children. | the association between caries prevalence and clinical (presence of visible plaque in the labial surfaces of maxillary incisors), microbiological (salivary levels of mutans streptococci) and dietary variables was evaluated in 142 1.0- to 2.5-year-old children attending public day-care nurseries in the city of piracicaba - são paulo. a significant difference in caries prevalence was observed between those children with and without visible plaque (chi2 = 12.08, p < 0.001). the mean ds (decayed sur ... | 1998 | 9701655 |
