Inadequacy of self-Implemented preventive measures to control caries increment due to poor dietary habits in 6 and 12 years old children in Riga, Latvia.

Aim: This study investigated whether the self-implemented preventive measures practiced among the 6 and 12 years olds in Riga, Latvia can control the caries increment due to poor dietary habits among this age groups.

Material and methods: Caries examination was performed on Thirty-eight 6 and thirty-nine 12 years olds by visual and bitewing radiographic examination at baseline and after 3 years. All participants and/or their parents completed dietary habits questionnaires. The data was analyzed using t-test, chi-square test, ANOVA and frequency tables, Wilcoxon and Fisher's tests (α=0.05).

Results: The mean (SD) values of caries experience at baseline/3-year period in 6- vs.12-year olds were as follows. DMFS: 0.72 (1.02)/3.13 (3.13) (p=0.0000) vs. 6.79 (5.14)/14.79 (9.86) (p=0.0000); dmfs: 11.26(8.71)/7.74 (4.86) (p=0.078) vs. 3.57 (2.03)/1.5 (0.71) (p=0.317). The statistical significance was reported only for the consumption of soft drinks (p=0.032) and sugared tea (p=0.018) for the 6 years olds, and for sugared tea (p=0.017) and number of teaspoons of sugar added to tea (p=0.0095) for the 12-years olds. There was positive caries increment in all the 6 and 12 years olds that reported significant increase in consumption of soft drinks and sugared tea, and increase daily number of teaspoons of sugar used in tea.

Conclusions: The present study demonstrated high cariogenic diet among the children in Riga, which is associated with increased caries experience that the currently practiced self-implemented oral hygiene measures was not capable of controlling.
