Background:
This cross-sectional study aims to investigate the association between socioeconomic and behavioural factors and dental caries among primary schoolchildren in Riyadh, Saudi Arabia.
Methods:
A total of 202 first-grade primary school students (mean age 6.2 years; 111 (55%) female) from public schools in Riyadh, Saudi Arabia, participated in the study. Socioeconomic and behavioural data were collected using the World Health Organization (WHO) oral health questionnaire completed by parents, while dental caries, measured using the decayed-missing-filled teeth (dmft) index, was assessed through clinical examination following WHO criteria. Ethical approvals were obtained from King Saud University (Institutional Review Board (IRB) No. 24/1240) and King's College London (LRS/DP-23/24-40999). Logistic regression was used to assess the association between parents' education and dental caries, adjusting for age, gender, dental visits in the last year, routine dental visits, oral hygiene, and sugar consumption.
Results:
The overall caries prevalence (dmft > 0) was 85.2% (172/202), with a mean dmft score of 5.43 (SE = 0.31). The percentage of children with untreated caries in deciduous teeth was 83.7% (169/202), with a mean of 4.96 (SE = 0.281). In the logistic regression, higher maternal education was negatively associated with caries experience (odds ratio (OR): 0.26, 95% confidence interval (CI): 0.07-0.99). A dental visit within the last year was positively associated with caries experience (OR: 3.46, 95% CI: 1.25-9.64). In contrast, routine dental visits for check-ups were negatively associated with caries experience (OR: 0.27, 95% CI: 0.08-0.90).
Conclusions:
Maternal education and consistent routine dental check-ups emerged as significant protective factors against dental caries. Emphasising preventive dental care and parental education may reduce the burden of caries among Saudi children.

Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Tooth Anatomy
The Crown, Neck, and Root
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 grinding food.
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 and...
Oral Cavity
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
