Learning disability (CLD) vs No learning disability (CNLD)

Care index (CI), permanent teeth · Children aged 1-18 years

The care index (met dental care need) for permanent teeth could not be meta-analyzed because no study reported variance; it was lower or equal in children with learning disabilities in 5 of 8 studies (certainty not graded).

Dental caries experience, care index and restorative index in children with learning disabilities and children without… 2019 All outcomes
Community and clinical settings (specialist paediatric dental clinics to school classrooms); 25 studies across 18 countries
Mean care index CLD 0.12 (SD 0.12) vs CNLD 0.18 (SD 0.27) for permanent teeth; CI in CLD was less than or equal to CNLD in 5 of 8 studies. Not meta-analyzed (no variance data reported in any study).

Learning disability (CLD) vs No learning disability (CNLD)

Restorative index (RI), permanent teeth · Children aged 1-18 years

The restorative index for permanent teeth could not be meta-analyzed (no variance data); it was lower or equal in children with learning disabilities in 4 of 9 studies, and the pattern suggested more extraction- than restoration-based care in CLD (certainty not graded).

Early childhood caries experience (mean dmft) · Children aged 1-18 years

In primary teeth, meta-analysis found no evidence of a difference in caries experience (dmft/deft) between children with and without learning disabilities (SMD 0.41, 95% CI -0.14 to 0.96; 8 studies; certainty not graded).

Learning disability (CLD) vs No learning disability (CNLD)

Dental caries in permanent teeth · Children aged 1-18 years

Across all learning disabilities, meta-analysis found no evidence of a difference in permanent-tooth caries experience (DMFT) between children with and without learning disabilities (SMD -0.43, 95% CI -0.91 to 0.05; 16 studies; certainty not graded).

Learning disability (CLD) vs No learning disability (CNLD)

Unmet dental treatment need · Children aged 1-18 years

Narrative reports from 6 studies suggested greater unmet dental treatment need in children with learning disabilities (5 of 6 studies), but no quantitative data were available (certainty not graded).

Community and clinical settings (specialist paediatric dental clinics to school classrooms); 25 studies across 18 countries
Six studies gave narrative reports of unmet dental need (Table 10); 5 of 6 reported greater unmet treatment need in CLD than CNLD, with no supporting numerical data.
