Aim: To identify different risks factors for history or activity of early childhood caries(ECC).
Methods: Cross-sectional study. 291 children from 2 to 5 years old from Panguipulli, Chile, were examined using Nyvad’s activity criteria[Nyvad et al: Caries Res 1999;33:252–260] by four clinicians (kappa intra/inter > .7). Category 1-3 was recorded as active caries lesions and 4-6 to history of caries. A children was categorized in four mutually exclusive groups (no history-no activitiy [NoNo]; activity only [NoYes]; history only (YesNo); or both [YesYes]). Parents completed a questionnaire to assess different possible risks factors. A multinomial logistic regression was done to detect differences in risk factors for groups (NoNo-NoYes-YesNo-YesYes). Reference level was no-history nor activity of ECC. Significance was set at p=0.05.
Results: Children without history or activity was 34.71%, with history was 32.99%, with active caries 7.9%, and with both 24.4%. Exclusively risk factor for activity of ECC was presence of visible plaque(p=0.041). Risk factors for both history and activity were bedtime-bottle(p=0.03), sugary-drinks(p=0.03), lack of dental control(p=0.018) and lack of vegetable-patch at home(p=0.024)
Conclusions: There are different risk factors associated with the history and activity of early childhood caries

There are different risk factors that explain early childhood caries history, activity (plaque) or both (night-bottle, sugary-drinks, lack of dental control and lack of vegetable-patch)
