Aim:
The aim of this cross-sectional study was to investigate whether family income modifies associations between dental caries and sex, age, mother's education, type of preschool, sugar intake, and toothbrushing.
Background:
Dental caries is a multifactorial dyanamic disease primarily mediated by biofilm and sugar.
Design:
A randomly selected sample of 308 Brazilian preschool children aged 1-3 years underwent a clinical oral examination for the assessment of moderate/extensive dental caries using codes 3-6 of the International Caries Detection and Assessment System. Mothers were asked to fill out a form addressing the child's demographic and socioeconomic characteristics as well as the frequency of sugar intake. Statistical analysis involved descriptive statistics, the chi-squared test, and Poisson regression models.
Results:
The prevalence of moderate/extensive dental caries was 42.5%. The adjusted model revealed that within low-income families (<2 times the monthly minimum wage), the prevalence of dental caries was higher among children with a high frequency of sugar intake (≥ twice per day) than in those with a low frequency of sugar intake (< twice a day) (RR = 1.79; CI: 1.38-2.33). In families with higher income (≥2 times the monthly wage), no significant association between sugar intake and dental caries was, however, found.
Conclusions:
In conclusion, monthly family income can modify the association between the high frequency of sugar intake and dental caries.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
