This was to determine dental caries determinants in the study participants.
This was a secondary data study extracted from primary data through a school-based study that recruited students from primary and secondary schools in a suburban population in Nigeria. The variables included age, gender, socio-economic status, oral hygiene status, type of parenting, birth rank, family size and presence of dental caries. The diagnosis of dental caries was based on the World Health Oral Health Survey recommendations while oral hygiene was determined using simplified-oral hygiene index (OHI-S). Data was analysed using STATA version 13, statistical significance was set at P < 0.05.
The prevalence of dental caries for the study population was 12.2%, DMFT and dmft were 0.16 and 0.06 respectively. Children within age groups 11–13 and 14–16 years had reduced chances of having dental caries (P = 0.01; P = 0.01); children with fair oral hygiene and poor oral hygiene had increased odds of having dental caries (P ≤ 0.001; P ≤ 0.001), last child of the family also had increased odds of having dental caries while children from large family size had reduced odds of having dental caries. This study also showed that first permanent molars and second primary molars were mostly affected by dental caries but there was no significant difference between distribution of the maxillary or mandibular jaw or between right and left quadrants.
Age, oral hygiene, birth rank and family size were the significant determinants of dental caries in the study population and the teeth mostly affected were first permanent molars and second primary molars.
