Obesity (Unclassified) vs Normal Weight or Non‐Obese

Dental caries prevalence · Brazilian children/adolescents in permanent dentition (BMI classified by CDC 2000 growth charts)

Normal-weight adolescents in the permanent dentition probably have greater odds of dental caries than obese peers (OR 2.53; moderate certainty).

Obesity (Unclassified) vs Normal Weight or Non‐Obese

Caries experience (mean DMFT) · Brazilian children in primary dentition (BMI classified by CDC 2000 growth charts)

Obesity may make little or no difference to caries experience (dmft) in the primary dentition (very low certainty).

Obesity (Unclassified) vs Normal Weight or Non‐Obese

Caries experience (mean DMFT) · Brazilian children/adolescents in permanent dentition (BMI classified by CDC 2000 growth charts)

Normal-weight adolescents may have higher caries experience (DMFT) than obese peers in the permanent dentition, but the evidence is very uncertain (very low certainty).

Overweight/obesity (combined) vs Normal Weight or Non‐Obese

Dental caries prevalence · Brazilian children/adolescents in permanent dentition (BMI classified by WHO 2006 Z-score)

A meta-analysis of 2 studies (permanent dentition, WHO 2006 Z-score) was rated very low certainty; the pooled effect was not shown in the article.
