Teriparatide 56.5 microg weekly in addition to standard care vs Teriparatide 20 microg daily in addition to standard care

Healing of MRONJ (remission) · People with established (manifest) MRONJ

It is very uncertain whether teriparatide 56.5 microg weekly in addition to standard care changes healing of MRONJ (remission) compared with teriparatide 20 microg daily in addition to standard care (very low certainty).

Caregiver help with child tooth brushing vs Children without dental caries

Dental caries · Children (deciduous and/or permanent dentition) in low- and middle-income countries

Caregiver help with tooth brushing was associated with 65% lower odds of dental caries (OR 0.35, 95% CI 0.13 to 0.93; 3 studies; very high heterogeneity; not GRADE-rated).

Tap water irrigation (monoject syringe) vs No rinsing

Presence of dry socket · Adults (>18 years) having permanent tooth extraction (predominantly mandibular third molars)

Tap water irrigation (monoject syringe) led to lower presence of dry socket compared with no rinsing; GRADE not reported.

Metal-free single crowns (full-contour zirconia) vs Composite strip crown

Restoration failure · Children with carious primary teeth

No comparative effect estimate was reported; failure rates were 3.3% and 15%.

Composite resin with etch-and-rinse (total-etch) adhesion vs Composite resin with self-etch adhesion (same universal adhesive)

Restoration failure · Children with carious primary teeth

No comparative effect estimate was reported; etch-and-rinse had a higher tabulated failure rate.

Resin infiltration vs Pre-treatment baseline before infiltration (T0); pooled as a within-arm before/after change

Color change of white spot lesion (color difference, T0 to T1) · Patients with post-orthodontic white spot lesions and permanent dentition

ICON resin infiltration significantly improved the color of post-orthodontic white spot lesions at 6 months (pooled Cohen's d/SMD 1.36, 95% CI 1.14 to 1.59; 4 studies, 458 teeth), although heterogeneity was very high (I2=98%) with a heavy outlier (Kannan); not GRADE-rated.

Bottle-feeding only vs Breastfeeding only

Early childhood caries (ECC) · Healthy children under 6 years in South Africa

No significant difference in caries odds was found between bottle-fed-only and breast-fed-only children (meta-analysis reported no difference; pooled estimate in an unavailable supplementary figure; not GRADE-rated).

Chlorhexidine gel vs Chlorhexidine, 0.2% to 2% (solution or gel)

Presence of dry socket · Adults (>18 years) having permanent tooth extraction (predominantly mandibular third molars)

Chlorhexidine gel 1% showed no clear difference in presence of dry socket compared with chlorhexidine gel 0.2%; GRADE not reported.

Genetically predicted gene expression (TWAS; S-PrediXcan with GTEx v8 cis-eQTL across 49 tissues; cross-tissue S-MultiXcan) vs ECC-unaffected children (association of genetically predicted expression)

Early childhood caries (ECC) - association with genetically predicted expression of IGSF5 (chr21q22.2) · Children up to age 5-6 years (European / European non-Hispanic ancestry); 843 ECC-affected vs 2124 unaffected across 5 cohorts (N=2974)

Genetically predicted IGSF5 expression reached the TWAS threshold for ECC (p = 7.22e-5) but was flagged as a possible false positive (LD misspecification) and not further considered; ungraded.

Referral to a specific dental treatment facility vs Generic advice letter to see a dentist

Number of caries in permanent teeth (DT index) · School children, primary school in Saudi Arabia

It is very uncertain whether referral to a specific dental treatment facility changes number of caries in permanent teeth (DT index) compared with generic advice letter to see a dentist (very low certainty).

Caries in upper primary incisors vs Reference (other primary tooth locations / caries-free)

Caries development in permanent teeth · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

Caries in upper primary incisors has the lowest tooth-specific predictive value for permanent-teeth caries (RR 1.6; single study; not GRADE-rated).

Pulpotomy with mineral trioxide aggregate (MTA) vs Pulpotomy with calcium hydroxide (Ca(OH)2)

Overall success (composite of clinical and radiographic success) · Human permanent teeth with irreversible pulpitis due to carious pulp exposure

MTA had a significantly higher pulpotomy success rate than calcium hydroxide (indirect comparison; numeric estimate not available); ungraded.
