ABSTRACT
Aims: Dental caries is a public health concern in many developing nations like Kenya. Slum children often do not have access to oral health care, and their oral health-related quality of life (OHRQoL) remains largely un-researched topic in Kenya. The present study was designed to determine the prevalence and severity of dental caries and its impact on the OHRQoL of a cohort of slum-dwelling children in a Nairobi slum.
Methods: In this descriptive cross-sectional study, a total of 452 children aged 12–14 years participated. Through a structured interview administered using a pretested questionnaire, data on child-oral impacts on daily performance (Child-OIDP), was collected to provide information on OHRQoL. Intra-oral clinical examination was conducted to assess caries experience using DMFT index. The data obtained was analyzed using STATA version 13.0 (STATA Corporation, College Station, Texas, USA). Logistic regression analysis was used to relate caries experience with OHRQoL.
Results: The prevalence of dental caries for the participants was 56.2%, with a mean DMFT of 1.72±2.22. The children who had DMFT scores of 1–3 were 1.5 times likely to report an oral impact on daily performance compared to those who had zero DMFT score (OR = 1.48; 95% CI: 0.89, 2.55). Children with DMFT scores of 4 and above were nearly four times likely to report oral impacts on their daily life (OR = 3.62; 95% CI: 1.51, 7.74).
Conclusion: In this study population, dental caries negatively affected the OHRQoL of the children.
