Food and nonalcoholic beverage marketing (exposure) vs No, less, or less powerful food marketing

Food intake · Children and adolescents (general population, aged under 20 years)

Food marketing was associated with a significant increase in children's food intake (pooled SMD, 0.25; combined RCT and nonrandomized evidence).

Resin-based fissure sealant vs Fluoride varnish

DMFS (decayed, missing, filled surfaces) increment, occlusal surfaces · Schoolchildren aged 6-12 years with sound occlusal surfaces of the first permanent molars

Pit and fissure sealant and fluoride varnish showed no statistically significant difference in DMFS increment at 24 months (SMD -0.13, 95% CI -0.67 to 0.40; I2=92%; not GRADE-rated).

Responsive complementary feeding (RCF) vs Other models of complementary feeding (traditional/non-responsive CF)

Overweight/obesity risk · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

Responsive complementary feeding probably reduces the risk of overweight/obesity versus other feeding models (RR 0.41, 95% CI 0.24 to 0.71; moderate certainty).

Single-visit root canal treatment vs Multiple-visit root canal treatment (two or more visits)

Post-treatment pain within 1 week (from first session) · People aged 10 years or above requiring root canal treatment; permanent teeth with completely formed apex and without internal resorption

Single-visit root canal treatment probably leads to higher post-treatment pain within 1 week (from first session) compared with multiple-visit root canal treatment (two or more visits) (moderate certainty).

Composite strip crowns with composite, fiber, or reverse metal posts vs Alternative post type

Restoration failure · Children with carious primary teeth after vital or non-vital pulp therapy

In one RCT, composite strip crowns with composite posts had an annual failure rate of 2.3% after 1 year.

Dental caries assessment (WHO/clinical diagnostic criteria; caries = DMFT>0) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental caries prevalence · 12-year-old children (permanent dentition) in Africa

Pooled caries prevalence in Uganda was 0.27 (95% CI 0.126 to 0.418; 3 article(s); not GRADE-rated).

Resin-modified glass-ionomer cement (RMGIC) restoration vs Amalgam, compomer, composite resin, or glass carbomer

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years

RMGIC had an annual failure rate of 1.9-16.9% (4 RCTs), lower than amalgam and similar to compomer/composite; low quality of evidence (ungraded).

Chlorhexidine vs Essential oils/herbal mouthwash

Reduction in level of contamination by particles >5 um (droplets) at <2 m from patient's oral cavity · Dental patients undergoing aerosol-generating procedures (AGPs) and the dental healthcare providers treating them

Chlorhexidine (CHX) led to lower reduction in level of contamination by particles >5 um (droplets) at… compared with essential oils/herbal mouthwash; GRADE not reported.

Combined antiretroviral therapy (cART) vs Monotherapy or dual antiretroviral therapy

Pulpotomy (full or partial) vs None (single-arm pooled success proportion)

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

Among 6 observational studies, pooled pulpotomy success was 92.6 per 100 (95% CI 0.86-0.96), very low certainty.

Responsive complementary feeding (RCF) vs usual care

Z score BMI · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

In one RCT, responsive complementary feeding lowered BMIz at 13 months versus control (0.23 vs 0.42, p=0.01; low certainty).

Pulpotomy with Calcium Enriched Mixture (CEM) 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

CEM and calcium hydroxide did not differ significantly in pulpotomy success (indirect comparison); ungraded.
