Non-syndromic cleft lip and palate (CLP) status and its oral microbiota (exposure/grouping) vs Children and adolescents aged 0-18 years without CLP (controls)

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.

Non-syndromic cleft lip and palate (CLP) status and its oral microbiota (exposure/grouping) vs Children and adolescents aged 0-18 years without CLP (controls)

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.

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.
