Body mass index and dental caries experience in Nepalese schoolchildren.

Regardless of the growth reference system used, children with either low or high BMI may be at risk of developing untreated dental caries lesions and related consequences. Both underweight and overweight/obese and dental caries share common risk factors, mostly dietary. Preventive and intervention approaches/strategies such as behavioural and dietary modifications should be implemented to improve both children's oral health and their nutrition in Nepal.
