Gingival index (GI) · Individuals assessed for periodontal health (mainly children and adolescents, age >2 years)
Persons with orofacial cleft have a higher gingival index than healthy controls (MD 0.15, 95% CI 0.11 to 0.19; low certainty).
1 finding from 1 review
Clinical attachment level (CAL) · Individuals assessed for periodontal health (mainly children and adolescents, age >2 years)
Clinical attachment level loss is greater in persons with orofacial cleft than in healthy controls (p<0.00001), but no pooled effect size was reported (ungraded).
1 finding from 1 review
Bleeding Index (BI) · Individuals assessed for periodontal health (mainly children and adolescents, age >2 years)
Bleeding index is significantly higher in persons with orofacial cleft than in healthy controls (p<0.0001), but no pooled effect size was reported (ungraded).
1 finding from 1 review
Oral microbiota composition · Individuals assessed for oral microbiota (mainly children and adolescents)
Oral microbiota composition differs between persons with orofacial cleft and healthy controls, synthesized qualitatively across 8 studies but not meta-analyzed (ungraded).

Probing pocket depth · Individuals assessed for periodontal health (mainly children and adolescents, age >2 years)
Persons with orofacial cleft have a greater probing pocket depth than healthy controls (MD 0.88, 95% CI 0.82 to 0.95; low certainty).
1 finding from 1 review
Plaque · Individuals assessed for periodontal health (mainly children and adolescents, age >2 years)
Persons with orofacial cleft have a higher plaque index than healthy controls (MD 0.29, 95% CI 0.24 to 0.34; low certainty).

Dental caries · Children and adolescents aged 0-18 years with non-syndromic cleft lip and palate (CLP)
Pooling 3 studies, children/adolescents with CLP were about 2.03 times more likely to have dental caries than non-CLP controls (p<0.005; low heterogeneity), though most included studies were at high risk of bias; the evidence is ungraded.

Lactobacillus spp. salivary/plaque counts (cariogenic microbiota) · Children and adolescents aged 0-18 years with non-syndromic cleft lip and palate (CLP)
A meta-analysis found no significant difference in mean Lactobacillus spp. levels between children with and without CLP, with high heterogeneity; the evidence is ungraded.
1 finding from 1 review
Streptococcus mutans count · Children and adolescents aged 0-18 years with non-syndromic cleft lip and palate (CLP)
A meta-analysis of 2 studies found no difference in mean Streptococcus mutans levels between children with and without CLP, with very high heterogeneity; the evidence is ungraded.

Periodontal conditions (gingival inflammation, bleeding on probing, probing depth, clinical attachment loss) · Children and adolescents aged 0-18 years with non-syndromic cleft lip and palate (CLP)
Narrative synthesis of 6 studies suggests children/adolescents with CLP have poorer periodontal status (higher gingival and plaque indices, deeper probing, more bleeding and attachment loss) and harbor periodontopathogens; no pooled estimate and the evidence is ungraded.
