OHI + 38% SDF (applied every 12 months) vs oral health instruction plus water

new root-surface carious lesions or restorations · community-dwelling older adults with root caries

SDF had a 28% preventative fraction at 24 months; no pooled estimate or GRADE rating was reported.

CBT vs alternative treatment

Reduction in pain intensity · People aged 12 years and over with painful TMD lasting 3 months or longer

Cognitive behavioural therapy (CBT) showed no clear difference in pain intensity at treatment completion compared with alternative (active) treatment (e.g. oral splint, medication,… (low certainty).

Nano-hydroxyapatite (nHA) dentifrice/paste (fluoride-free or fluoridated) vs nHA-free / fluoride-free (negative) control

Mineral loss (transversal microradiography) · Enamel/dentin specimens with initial caries lesions (or sound surfaces) in intraoral (in situ) appliances worn by patients

Under remineralizing conditions, nHA produced significantly more remineralization than the negative control (MD 350, 95% CI 179 to 521; very low certainty).

Relaxation vs Occlusal (oral) appliance

Patient‐reported pain intensity or pain relief (VAS, NRS or categorical scale) · People aged 12 years and over with painful TMD lasting 3 months or longer

Relaxation showed no clear difference in pain intensity compared with occlusal (oral) appliance; GRADE not reported.

CBT vs alternative treatment

Mental distress · People aged 12 years and over with painful TMD lasting 3 months or longer

Cognitive behavioural therapy (CBT) may leads to lower psychological distress at follow-up compared with alternative (active) treatment (e.g. oral splint, medication,… (low certainty).

CBT vs alternative treatment

Disability caused by pain at follow-up · People aged 12 years and over with painful TMD lasting 3 months or longer

Cognitive behavioural therapy (CBT) showed no clear difference in disability caused by pain at treatment completion compared with alternative (active) treatment (e.g. oral splint, medication,… (low certainty).

Machine-learning algorithms for dental caries detection vs Different machine-learning algorithms compared with one another / against the reference caries diagnosis

Diagnostic accuracy for root caries detection · Dental radiographic/intraoral images of human teeth (X-ray and photographic)

One study reported machine-learning accuracy for root caries detection (97.1%, support vector machine); not pooled and not graded.

Fluoride-free nano-hydroxyapatite (nHA) dentifrice/paste vs Sodium fluoride (control) toothpaste

Mineral loss (transversal microradiography) · Enamel/dentin specimens with initial caries lesions (or sound surfaces) in intraoral (in situ) appliances worn by patients

Under demineralizing conditions, nHA allowed significantly more enamel demineralization than NaF (MD 1625, 95% CI 553 to 2697; very low certainty).
