Impact of oral mucosal conditions on oral health-related quality of life in preschool children: a hierarchical approach
International Journal of Paediatric Dentistry 2014;
To determine the impact of oral mucosal conditions on OHRQoL in preschool children.
A cross-sectional study was carried out with a selected representative sample of 724 children aged 2–5 years and their parents/caregivers. Data were collected through interviews with parents/caregivers, who also answered the B-ECOHIS. A clinical oral examination was performed to determine oral mucosal conditions, dental caries, dental trauma, and malocclusion. Data analysis involved descriptive statistics, the Kolmogorov–Smirnov normality test, the Mann–Whitney U-test and hierarchically adjusted Poisson regression models (P < 0.05, 95% CI).
The prevalence of oral mucosal conditions was 50.7%, the most prevalent of which were melanotic macules (17.8%), oral ulcers (11.0%), Fordyce's spots (9.4%), geographic tongue (5.2%), fissured tongue (1.9%), median rhomboid glossitis (1.8%), and fistula (1.4%). In the final multivariate model, child with 5 years of age (RR = 1.60; 95% CI: 1.08–2.38; P = 0.020), with presence of fistula (RR = 1.94; 95% CI: 1.27–2.95; P = 0.002), and with dental caries (RR = 2.58; 95% CI: 2.00–3.35; P < 0.001) had a negative impact on children's OHRQoL.
Child with 5 years of age, presence of fistula, and dental caries were associated with a negative impact on the quality of life of preschool children.
