Dia (Initial caries) Dma (Manifest caries) Di+mFA or DFa (Total approximal caries prevalence fillings) |
Higher approximal dental caries in overweight and obese adolescents than normal and underweight. Caries experience at 15 years predicted by early childhood caries experience at age 3, plaque on incisors at age 1 year, infrequency of tooth brushing with fluoride toothpaste , consumption of caries-risk snacks more than three times a day at age 1 years, consumption of sweets < once per week at age 3 years, parents were born abroad, parents’ poor attitudes to dental health and psychosocial factors |
Initial caries: 86% of total caries experience Approximal caries prevalent in 67% of 15 yr old children Mn Di+mFa at 15 yrs Overall sample=3.21 (SD=3.95) Underweight = 2.94 (SD=3.62) Normal weight = 4.64 (SD=5.15) Overweight = 4.18 (SD=5.14) Obese = 6.29 (SD=5.04) Mn DmFa at 15 yrs Overall sample 0.42 ( SD=1.13) Underweight = 0.35 ( SD=−0.89) Normal weight = 0.83 ( SD=1.93) Overweight = 0.84 ( SD=2.02) Obese = 0.79 ( SD=1.63) BMI: Overweight: 16% Obese: 4% Low-normal weight: 84% |

Child physical status measured as (i) Fat Mass% (FM; using Dual energy X-ray), and (ii) BMI Children with higher body fat mass (FM%) had higher DMFT/dmft rates than those with normal FM, but compble dmft/DMFT rates with underweight children using FM%-DXA No association found using BMI (McCarthy or WHO cut-offs) as obesity estimate |

Deft (6 yrs) DFT (10–12 yrs) DFSa (approximal surfaces of permanent teeth) |
Dental caries higher prevalence in obese than non-obese At 12-years of age, children who had a history of obesity at 4-yrs of age had higher rates of caries than children who had history of healthy weight at 4-years of age. Obese/overweight children at 4 yrs old and who remained overweight / obese at 5, 7 and 10 years of age had significantly more approximal carious surfaces (DFSa) than normal weight children in all age groups Overweight / obese children at 4 yrs old but with normal weight at 5, 7 and 10 yrs of age had significantly fewer approximal carious surfaces than children with normal weight from 4 to 10 years of age Gender: Girls at 10 and 12 yrs old had more caries affected teeth than boys SES: Caries prevalence decreased with increasing SES |

Non-cavitated lesions: (d1-2) Cavitated/dentinal lesions: (d3-6) Filled lesions (f); missing lesions (m) d3-6mfs; d1-6mfs |
Higher caries (dmft:1–6) associated with higher weight-for-age. For d1-6mfs: higher consumption of soda drinks, older child age, higher weight-for-age, visiting a dentist for treatment, higher baseline caries level of the child and caregiver, fatalistic belief of the caregiver, and living in relatively disadvantaged low-income neighbourhood. |
Almost 25% of children had low weight for age |
