title: Sweets and other sugary products tend to be the primary etiologic factors in dental caries.
abstract: The aim of this study was to analyze the relationships between caries incidence and each of seven caries-related factors in a group of 15- to 18-yr-olds as well as in single and combined subgroups representing favorable or less favorable fractions of six of the factors. Sixty-nine 18-yr-olds were interviewed about consumption of sweets and other sugar-containing products during the past 3 yr and examined for oral hygiene, salivary counts of mutants streptococci and lactobacilli, salivary flow rate and oral sugar clearance time at the ages of 15 and 18. Simple linear correlations and a stepwise multiple regression analysis were used to compare ranks and explanatory values. The highest correlations were obtained for intake of sweets and intake of other sugary products, with r values increasing from 0.25 and 0.16, respectively, in the total material to 0.70 and 0.67 in less favorable fractions of oral hygiene, salivary flow rate and other sugary products in the former case, sweets in the latter. The stepwise multiple regression analysis revealed that sweets and other sugary products contributed 12 percentage points to the total explanatory value, which was as low as 19%.
