Abstract
AIM: To investigate whether children with obesity experienced more erosion and caries than children with normal weight. METHODS: This study involved children aged 7-15 years. The study and control group comprised 32 children with BMI > 98th centile and 32 healthy children with normal BMI-for-age, respectively. O'Sullivan Erosion Index and WHO Caries Index were used in the examination of erosion and caries, respectively. Stimulated salivary flow rate, buffering capacity, Streptococcus mutans and lactobacilli counts (CFU/ml) were evaluated. A cross-sectional questionnaire survey was employed to collect information on participant's demographic background, oral health history and habits, and utilisation of dental care services. RESULTS: Children with obesity were more likely to have erosion than healthy children (p < 0.001), and had more erosion in terms of severity (p < 0.0001) and area affected (p < 0.0001), but not in the number of surfaces affected (p = 0.167). Posterior teeth were less likely than anterior teeth to be affected by erosion (OR 0.32, 95 % CI 0.012-0.082). Gender had no effect on erosion. There were no statistically significant differences in the DMFT, saliva profiles or questionnaire responses between the groups. CONCLUSIONS: Children with obesity may have high risk of dental erosion, but do not necessarily have higher risk of dental caries than children with normal weight.
