Abstract
Background
Preschool years are a critical period in the development of a healthy child. The consequences of poor oral health in preschool children reach beyond dental problems, with oral health-related quality of life (OHRQoL) being associated with overall systematic health as well as one’s quality of life. The purpose of this study was to assess the prevalence of dental caries and its impacts on the OHRQoL in a sample of preschool children in Kisarawe.
Methods
A cross-sectional based study was conducted in 2017. A total of 1106 preschool children completed a face-to-face interview, using a translated Kiswahili version of the Michigan Oral Health-related Quality of Life Scale (MOHRQoL) –Child Version (2003), and underwent clinical oral examination using WHO (1997) criteria.
Results
The decayed component was the most prevalent (dft = 2.08) and the Significant Caries Index (SiC) was 5.54 double of the (dft), showing polarization of dental caries in the studied population. After adjusting for appropriate covariates, preschool children of age 5 and 6 years old were more likely to have decayed tooth [Adjusted OR = 3.02, (95% CI =2.01–4.54)] and [Adjusted OR = 2.23, (95% CI = 1.55–3.20)] respectively. Preschool children without visible plaque on the buccal surface of upper anterior teeth were less likely to have decayed teeth [Adjusted OR = 0.21, (95% CI = 0.09–0.45)]. Regarding measurements of oral health-related quality of life using the MOHRQoL, only preschool children who reported on ‘do your teeth hurt you now?’ and ‘do kids make fun of your teeth?’ were more likely to have a decayed tooth [Adjusted OR = 1.74, (95% CI = 1.12–2.71)] and [Adjusted OR = 1.87, (95% CI = 1.11–3.15)], respectively.
Conclusion
Findings from this study suggest that dental caries affects a significant portion of preschool children and, was associated with poor oral hygiene. The overall impacts of dental caries prevalence to OHRQoL were low in this sample of preschool children. Children having caries (independent variable) were shown to report more frequently that ‘do your teeth hurt you now?’ and ‘do kids make fun of your teeth?’ were more likely to have a decayed tooth among preschool children in Kisarawe, Tanzania.
