Oral-health promotion programs (OHPPs): community-based oral-health education/training, supervised toothbrushing with fluoride toothpaste and topical fluoride, dental screening, and dietary advice vs No oral health promotion program

Oral health-related quality of life · Adolescents (10-19 years)

Oral health promotion programs have a positive effect on OHRQoL in adolescents (narrative synthesis; low methodological quality of included evidence; no pooled estimate or GRADE rating).

Outer carious dentin (by lesion depth/location) vs Inner carious dentin

MMP-8 location/depth · Human ex vivo carious dentin

MMP-8 showed no statistical difference by lesion location; the evidence is very uncertain (very low certainty).

Cariogram multivariable caries-risk model (including modified/reduced-predictor versions) vs Alternative prediction model(s) within the same study, or no formal comparator (models compared descriptively; no between-model statistical test)

Predictive performance of the Cariogram for caries increment (negative likelihood ratio, LR-) · Children/adolescents (coronal caries) and older adults (root caries); populations from areas with varying caries risk

Modified Cariogram models showed negative likelihood ratios of about 0.5-0.61, above the useful rule-out threshold; no pooled estimate; ungraded.

  • Multivariable prediction models of caries increment: a systematic review and critical appraisal. 2023 All outcomes
    Follow-up >=1 year (included studies 1-5 years) · Oral health care; children/adolescents and older adults; multiple countries · Model validation studies
    Review-stated LR- range 0.5-0.61 across the Cariogram validation models (with one exception). Model performance was largely unaffected by removing the predictors mutans streptococci in saliva, saliva secretion and…

Light vibrational forces (LVF) vs Conventional orthodontic appliance treatment

Change in angulation of teeth adjacent to the space (molar and canine tipping/rotation) · Adolescents and adults with malocclusion undergoing orthodontic treatment with fixed or removable appliances
1 finding from 1 review

Older age vs Younger adults (population mean age <=33.4 years)

Oral health-related quality of life · Adolescents (10-19 years)

The abstract reports older age is associated with worse OHRQoL, but the body notes the evidence on age is limited and conflicting (narrative synthesis; no pooled estimate or GRADE rating).

  • Oral-health-related quality of life in adolescents: umbrella review. 2023 All outcomes
    Community/school/clinic settings; adolescents 10-19 years; included reviews conducted in multiple countries
    Worse oral health status, older age, female sex and worse socioeconomic status were significantly associated with worse OHRQoL. [Body: the influence of religion and age on OHRQoL is unknown; Biological data such as…

Resin infiltration vs Self-assembling peptide P11-4

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…

Resin infiltration did not differ significantly from P11-4 alone (SMD -0.39, 95% CI -0.97 to 0.20); certainty of evidence not assessed (no GRADE).

Glass ionomer cement vs Resin-modified glass ionomer cement (RMGIC)

Secondary caries · Patients requiring dental restoration; deciduous (primary) teeth

Over 2 or more years in deciduous teeth, GIC probably had a higher risk of secondary caries than RMGIC (RR 1.92, 95% CI 1.03-3.56; moderate certainty).

Eugenol-based temporary cement vs Eugenol-free temporary cement

Pulp necrosis · Vital teeth

The pooled incidence with eugenol-based temporary cement was 3.34%.

38% SDF plus potassium iodide (KI) (indirect pulp capping) vs Resin-modified glass ionomer cement (RMGIC)

Secondary prevention of caries · children with deep occlusal carious lesions in permanent molars

No significant difference in secondary caries prevention was reported; no effect estimate or GRADE rating was reported.

Elective neck dissection (at time of primary tumour resection) vs Therapeutic (delayed) neck dissection

Adverse events associated with treatment · 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 higher adverse events associated with treatment compared with therapeutic (delayed) neck dissection (moderate certainty).

Compomer (Dyract) vs Glass ionomer cement (GIC)

Secondary caries · Patients requiring dental restoration; permanent teeth

Over 2 or more years in permanent teeth, the effect of compomer versus GIC on secondary caries is very uncertain (RR 3.20, 95% CI 0.59-17.33; very low certainty).

Bioactive restorative materials (RMGIC and compomer combined) vs Resin composite restoration

Secondary caries · Patients requiring dental restoration; deciduous (primary) teeth

In deciduous teeth at 1 year, pooled bioactive materials (RMGIC and compomer) showed no significant difference from resin composite in secondary caries (RR 0.54, 95% CI 0.07-4.10; ungraded).

Low‐level laser therapy vs Conventional orthodontic appliance treatment

Rate of orthodontic tooth movement during space closure stage (maxillary arch), mm/month · Adolescents and adults with malocclusion undergoing fixed orthodontic appliance treatment

It is very uncertain whether low level laser therapy (LLLT) changes rate of orthodontic tooth movement during space closure stage… compared with conventional orthodontic appliance treatment (very low certainty).
