Secondary caries · Patients requiring dental restoration; permanent teeth
Over 2 or more years in permanent teeth, GIC probably reduces secondary caries versus resin composite (RR 0.50, 95% CI 0.28-0.91; moderate certainty).

1 finding from 1 review
Impaired OHRQoL, qualitative synthesis: relative effect not estimable across the 13 studies (13,864 participants); moderate quality of evidence (GRADE).

Secondary caries · Patients requiring dental restoration; deciduous (primary) teeth
Over 2 or more years in deciduous teeth, the difference in secondary caries between giomer and RMGIC is uncertain (RR 1.66, 95% CI 0.49-5.61; low certainty).

Salivary flow rate (unstimulated) · Elderly (>60 years) and medically compromised adults with xerostomia / dry mouth
In elderly and medically compromised people with xerostomia, chewing sugar-free gum daily for two or more weeks produces a small but statistically significant increase in unstimulated whole salivary flow rate versus no gum (SMD 0.44, 95% CI 0.22 to 0.66); certainty of evidence was not formally graded.

Dry mouth (xerostomia) · Elderly (>60 years) and medically compromised adults with xerostomia / dry mouth
Gum chewing was linked with improved self-reported xerostomia / dry mouth in most studies (12 of 17 positive, 5 no effect); heterogeneous instruments precluded meta-analysis.
