Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

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

Population: Children aged 1-18 years
11 questions
OutcomeEffectEvidenceStatus / GRADE
Caries experience in primary teeth (dmft/deft)
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).

SMD 0.41 [-0.14, 0.96]8 studiesUngraded
Caries experience in permanent teeth (DMFT)
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).
Source: Fig. 2 (forest plot, TOTAL diamond); Results 'Caries experience in the permanent teeth for CLD compared to CNLD'; Tables 3-5 · same question in other reviews
SMD -0.43 [-0.91, 0.05]16 studiesUngraded
Caries experience in permanent teeth (DMFT)
Disability: mixed learning disabilities
In children with mixed/other learning disabilities, permanent-tooth caries experience did not differ from children without learning disabilities (SMD 0.26, 95% CI -0.94 to 1.47; 2 studies; certainty not graded).
Source: Fig. 2 (mixed subtotal); Results; Table 5 · same question in other reviews
SMD 0.26 [-0.94, 1.47]2 studiesUngraded
Care index (CI), permanent teeth
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).
Source: Results 'Care, and restorative indices (permanent teeth)'; Table 2; Discussion · same question in other reviews
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).8 studiesUngraded
Caries experience in permanent teeth (DMFT)
Disability: autism
In children with autism, permanent-tooth caries experience did not differ from children without learning disabilities (SMD -0.28, 95% CI -1.31 to 0.75; 6 studies; certainty not graded).
Source: Fig. 2 (autism subtotal); Results; Table 4 · same question in other reviews
SMD -0.28 [-1.31, 0.75]6 studiesUngraded
Unmet dental treatment need
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).
Source: Results 'Narrative reports of unmet dental need'; Table 10 · same question in other reviews
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.6 studiesUngraded
Restorative index (RI), permanent teeth
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).
Source: Results 'Care, and restorative indices (permanent teeth)'; Table 2; Discussion · same question in other reviews
Mean restorative index CLD 0.15 (SD 0.14) vs CNLD 0.28 (SD 0.33) for permanent teeth; RI in CLD was less than or equal to CNLD in 4 of 9 studies. Not meta-analyzed (no variance data). In CLD the RI tended to exceed the…9 studiesUngraded
Caries experience in permanent teeth (DMFT)
Disability: Down syndrome
In children with Down syndrome, permanent-tooth caries experience was lower than in children without learning disabilities (SMD -0.73, 95% CI -1.28 to -0.18; 8 studies; certainty not graded).
Source: Fig. 2 (Down syndrome subtotal); Results; Table 3 · same question in other reviews

Caries experience in primary teeth (dmft/deft)
Disability: autism
In children with autism, primary-tooth caries experience did not differ from children without learning disabilities (SMD 0.43, 95% CI -0.53 to 1.39; 4 studies; certainty not graded).

Caries experience in primary teeth (dmft/deft)

In children with Down syndrome, primary-tooth caries experience did not differ from children without learning disabilities (SMD 0.55, 95% CI -0.40 to 1.52; 3 studies; certainty not graded).

Disability: mixed learning disabilities
For mixed/other learning disabilities, the single primary-teeth estimate showed no difference in caries experience (SMD -0.10, 95% CI -0.34 to 0.14; 1 study; certainty not graded).
