Streptococcus mutans count · Children and adolescents aged 0-18 years with non-syndromic cleft lip and palate (CLP)
No difference in mean Streptococcus mutans presence was reported; GRADE was not reported.

Mean DFR (decayed, filled root teeth) · adults
Patients with periodontitis had a significantly higher mean DFR (WMD 1.13).

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.

Crown caries · adults
Periodontitis was associated with a small increase in crown caries odds (OR 1.03).
1 finding from 1 review
Periodontitis (clinical attachment loss) · Adults in case-control studies (oral cancer patients vs healthy controls)
Clinical attachment loss was significantly greater in oral cancer patients than controls (SMD 1.94, 95% CI 0.22-3.66), though heterogeneity was very high (I2=96.7%); ungraded.

Plaque · Orthodontic patients undergoing comprehensive treatment (late mixed or permanent dentition, no active caries)
In randomized trials, clear aligners probably reduce plaque accumulation versus fixed appliances, though the subgroup estimate is imprecise and its CI crosses no effect (SMD -1.79, 95% CI -3.63 to 0.04; moderate certainty).

White spot lesion incidence · Orthodontic patients undergoing comprehensive treatment (late mixed or permanent dentition, no active caries)
Most studies reported a lower incidence of white spot lesions with clear aligners than fixed appliances, but heterogeneous assessment methods precluded meta-analysis (ungraded).

Plaque · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)
Chlorhexidine mouthwash may reduce the Plaque Index versus blank control in the short term (WMD -0.70, 95% CI -1.12 to -0.27), but the evidence is very uncertain (very low certainty).

Severity of white spot lesions (surface area and depth) · Orthodontic patients undergoing comprehensive treatment (late mixed or permanent dentition, no active caries)

Gingival index (GI) · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)
Chlorhexidine mouthwash may reduce the Gingival Index versus blank control in the short term (WMD -0.54, 95% CI -0.96 to -0.13), but with very high heterogeneity the evidence is very uncertain (very low certainty).
