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).

Shear bond strength (SBS) of metallic orthodontic brackets · Extracted permanent human teeth (enamel); sound or demineralized
CPP-ACP enamel pre-treatment before bonding did not significantly affect the shear bond strength of metallic orthodontic brackets (MD 1.163 MPa, 95% CI -0.321 to 2.648; ungraded).

Recurrence · Adults with oral cavity cancer
It is very uncertain whether elective radical (comprehensive) neck dissection changes recurrence compared with elective selective neck dissection (very 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.

Remineralization / reduction in lesion severity (change in QLF, laser fluorescence, or lesion area) · Patients with white spot lesions / early caries lesions (WSLs/ECLs), including orthodontic and non-orthodontic lesions, active caries…
CPP-ACP did not differ significantly from control (SMD -0.18, 95% CI -0.49 to 0.14); certainty of evidence not assessed (no GRADE).

Risk of malnutrition (younger children, 6 months to 6 years) · Children aged ≤6 years (early childhood)
One Nepalese cross-sectional study found no significant association between severe ECC and malnutrition risk in children under 6 (mean difference 0.13, p=0.609); ungraded.

Overall success (composite of clinical and radiographic success) · Patients with carious pulp exposure in mature permanent teeth
MTA increases clinical and radiographic success versus CH in mature teeth (moderate certainty).

Cathepsin B (CT-B) presence/activity · Human coronal carious dentin and sound dentin
Cathepsin B may be increased in carious dentin compared with sound dentin (very low certainty).

Mortality (overall survival) · Adults with oral cavity cancer (tongue or floor of mouth) and clinically negative neck nodes
Elective neck dissection (at time of primary tumour resection) probably leads to lower mortality (overall survival) compared with therapeutic (delayed) neck dissection (moderate certainty).
1 finding from 1 review
Disease-free survival · Adults with oral cavity or oropharyngeal cancer
Sentinel node biopsy (neck dissection only if biopsy positive) showed no clear difference in disease-free survival (new disease, progression, and mortality) compared with elective neck dissection (low certainty).

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.
