Temporomandibular disorders (TMD), TMJ arthritis/involvement and orofacial pain · Children and adolescents with juvenile idiopathic arthritis (JIA)
TMD and TMJ arthritis/involvement (and orofacial pain) were consistently reported more frequently in children/adolescents with JIA than in healthy peers, though several studies had small samples; no pooled estimate (ungraded).

Developmental defects of enamel measured by any validated index · Children and adolescents with juvenile idiopathic arthritis (JIA)
A single small study suggested developmental enamel defects were more frequent in children with JIA, but the evidence is insufficient (1 study; ungraded).
1 finding from 1 review
The only study reporting developmental enamel defects [22] found the condition more frequent among children with JIA than healthy peers, but the sample size was too small to draw any reliable conclusion.

Oral ulcerations · Children and adolescents with juvenile idiopathic arthritis (JIA)
A single study reported more oral ulcerations in children with JIA (5/41) than without JIA (1/41); evidence is limited to one study (ungraded).

Dental maturation (tooth calcification) · Children and adolescents with juvenile idiopathic arthritis (JIA)
Evidence on dental maturation was divergent across two studies (one found more advanced maturation in JIA, one found no difference); no clear conclusion (ungraded).

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).

Oral health-related quality of life · Children and adolescents with juvenile idiopathic arthritis (JIA)
Evidence on OHRQoL was limited: one study found no significant difference between groups while another found orofacial symptoms affected daily life more in JIA; no pooled estimate (ungraded).
1 finding from 1 review
Santos et al. [29] found oral health status had little or no effect on well-being with no significant difference between JIA and healthy groups (SF:13-B-PCPQ); Leksell et al. [38] found orofacial symptoms influenced…

Plaque index (PI) / oral hygiene · Children and adolescents with juvenile idiopathic arthritis (JIA)
Evidence on oral hygiene/dental plaque was inconsistent: several studies found higher plaque in the JIA group while others found no difference; no pooled estimate (ungraded).
1 finding from 1 review
Some studies showed a statistically higher Plaque Index or Simplified Oral Hygiene Index (OHI-S) in the JIA group [23, 25, 28, 31]; other studies did not find this association [22, 26, 27, 29, 30, 39]. Meta-analysis…

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).
1 finding from 1 review
Many studies documented poorer periodontal status among children/adolescents with JIA: more gingival inflammation and bleeding [22, 29, 31], bleeding on probing [25], deeper probing depth [25, 26] and periodontal…

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).

Dental caries in permanent teeth · Children and adolescents with juvenile idiopathic arthritis (JIA)
There was no significant difference in dental caries of the permanent teeth (DMFT) between children/adolescents with JIA and healthy peers (pooled MD -0.08, 95% CI -0.42 to 0.26; 6 cross-sectional studies; no heterogeneity I2=0%; ungraded).

Prevalence and severity of oral and TMJ diseases/conditions (periodontal status and dental caries) · Children and adolescents with juvenile idiopathic arthritis (JIA)
Some studies suggested greater JIA disease activity/severity (and certain medications) was associated with worse periodontal and caries outcomes, but small samples meant no solid conclusion could be drawn (ungraded).
