Objectives: To examine socioeconomic and behavioural determinants of caries experience among primary school students in Riyadh, Saudi Arabia.

Methods: A stratified sample from 16 primary schools in Riyadh was selected. A total of 1,087 students aged 6-11 years were included in the study between October 2017 to January 2018. The World Health Organization (WHO) criteria for assessing dental caries were used to collect clinical data. Socioeconomic and behavioural data were also collected using a modified version of the WHO questionnaire. Caries experience were indicated by the sum of decayed, missing, and filled teeth in primary and permanent dentition (dmft, DMFT). Linear regression was used to examine factors associated with caries experience.

Results: More than 72% of children had dmft score of 1 or more with mean 3.11 (SE= 0.097), and 25.6% had a DMFT of 1 or more with mean 0.55 (SE= 0.036). The percentages of children with untreated dental caries in primary and permanent teeth were 63.4% and 23.5% with means (2.26, 0.49), respectively. In the regression model, maternal education was the strongest predictor of caries experience in primary teeth.

Conclusions: Despite the availability of free dental services in Saudi Arabia, most of the caries experience reflected untreated dental caries. This finding highlights cultural and financial barriers to the use of dental services. The findings also highlight the importance of maternal education as a strong predictor of children’s caries.
