Juvenile idiopathic arthritis (JIA) vs Children and adolescents without JIA (healthy peers)

Juvenile idiopathic arthritis (JIA) vs Children and adolescents without JIA (healthy peers)

Dental erosive wear · Children and adolescents with juvenile idiopathic arthritis (JIA)

No eligible studies reported dental erosive wear, so its association with JIA could not be assessed (evidence gap).

Juvenile idiopathic arthritis (JIA) vs Children and adolescents without JIA (healthy peers)

Periodontal conditions (gingival inflammation, bleeding on probing, probing depth, clinical attachment loss) · Children and adolescents with juvenile idiopathic arthritis (JIA)

Periodontal conditions (gingival inflammation, bleeding, probing depth, attachment loss) were more frequently reported in children/adolescents with JIA than in healthy peers, although not all studies agreed; no pooled estimate (ungraded).

Juvenile idiopathic arthritis (JIA) vs Children and adolescents without JIA (healthy peers)

Caries in primary teeth: dmft (3 years) · Children and adolescents with juvenile idiopathic arthritis (JIA)

There was no significant difference in dental caries of the primary teeth (dmft) between children with JIA and healthy peers (pooled MD -1.16, 95% CI -3.02 to 0.71; 3 cross-sectional studies; very high heterogeneity I2=87.9%; ungraded).
