Abstract


The correlation betwwen the buffer cappacity, Streptoccocci of "mutans" group counts in saliva and caries (DFs index) in school children from Caldas, Antioquia, Colombia, between the age of 9 to 11 years old was taken. In spite of the population had shown Streptoccoccus of "mutans" group counts in saliva cultures (92.35%). Standar deviation was high: 368 x10^7 CFU/ml. Ten children between 0 and 1 x10^7CFU/ml and 9 children had between 1.000 and 3.000 x10^7 CFU/ml. Most of the population had high buffer capacity (mean 5.95) (Done by the final pH). Less than 25% was found to have buffer capacity lower than ´5 and the 25% had show a buffer capacity higher than 6.75. In boys the mean of buffer capacity was significantly higher (6.01) than the girls (5.44) p=0.007)). The DFs had shown a linear correlation with Streptoccocci of "mutans" group counts in salivar (r= 3.4 α=0.00) and a negaive correlation woth buffer cappacity (r= -0.19 α=0.00079). In the boys the association between Streptoccoccus of "mutans" group and DFs are similar to the group sample (r= 0.30 α=0.005) but in the girls are stronger (r= 0.67 α=0.0079). In the children with low caries (DFs less than 5) no association was found between the variables. In the group with more caries (DFs >19), DFs only had relation with Streptoccocci of "mutans"group (r= 0.435 α=0.0018). This group of high caries had als correlation between Streptoccocci of "mutans" group and oral higiene (r= 0.435 α=0.0018). In others parallels studies in the same population, Streptoccocci of "mutans group had shown a tendency of relation with sucrose intake.
