Use of caries prevention tools and associated caries risk in a suburban population of children in Nigeria

To determine the association between use of recommended oral self-care (ROSC) caries prevention tools and presence of dental caries in children resident in suburban Nigeria.
Secondary analysis was conducted for a dataset generated for 1–12 years old children recruited through a household survey. Information on use of ROSC caries prevention tools (brushing more than once a day, use of fluoridated toothpaste always, and eating sugary snacks between main meals less than once a day), use of oral health adjuncts (dental floss, mouth rinses, other tooth cleansing agents) and presence of caries were extracted. The odds of having caries when ROSC caries prevention tools were used singly or in combination, were determined using multivariate logistic regression adjusted for age and sex.
The single or combined use of ROSC caries prevention tools had no statistically significant association with presence of caries. Brushing more than once a day reduced the odds of having caries while consumption of sugar between meals once a day or more increased the odds of having caries after adjusting for age and gender. The use of two ROSC caries prevention tools reduced the risk for caries (AOR 0.28; 95 % CI 0.05–1.53) when adjusted for age. The converse was observed when adjusted for gender (AOR 1.15; 95 % CI 0.38–3.45). The largest effect size was observed when sugary snacks were taken once a day or more between meals after adjusting for age (AOR 5.74; 95 % CI 0.34–96.11).
The use of a combination of fluoridated toothpaste and twice-daily tooth brushing had the largest effect on reducing the chance for caries in children resident in Ile-Ife, Nigeria.
