Baby-led weaning (BLW) vs Traditional complementary feeding (TCF)

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

Among observational studies, baby-led weaning was associated with lower odds of overweight/obesity than other feeding models (OR 0.37, 95% CI 0.25 to 0.55), but certainty is very low.

Traditional screening (referral card given if the inspecting dentist judges the child needs to see a dentist) vs No screening

Dental attendance · School children (aged 4 to 15 years), primary and secondary schools in the UK and India

    3 to 4 months
    Data not pooled; 6281 participants (4 RCTs); Very low. There was substantial heterogeneity, in part due to study design (3 cluster-RCTs and 1 individually randomised trial). We are unable to draw conclusions about this…

Periodontal treatment: scaling and root planing (SRP) plus advice vs Community care: advice only

Cardiovascular events · Patients with cardiovascular disease and chronic periodontitis
1 finding from 1 review

Baby-led weaning (BLW) vs Traditional complementary feeding (TCF)

Infant weight-length gain (achievement of adequate weight) · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

Baby-led weaning/BLISS did not significantly influence infant weight-length (adequate weight) gain versus other complementary feeding models (pooled OR 1.36, 95% CI 0.18 to 10.51; ungraded).

Selective carious tissue removal (selective excavation, SE) vs Non-selective or complete carious tissue removal

Pulp exposure during caries removal · Children with dentine caries in primary and permanent teeth

Partial caries removal was reported to reduce pulp-exposure risk by 77% versus complete caries removal (RR 0.23; ungraded).

1 finding from 1 review

Artemisia desertorum spreng (Shahaosan) vs placebo

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

Artemisia desertorum spreng (Shahaosan) showed no clear difference in presence of dry socket compared with placebo; GRADE not reported.

Cetylpyridinium chloride (CPC) vs Water

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

Cetylpyridinium chloride (CPC) may leads to lower reduction in level of contamination by particles >5 um (droplets) at… compared with water (low certainty).

Selective carious tissue removal (selective excavation, SE) vs Non-selective or complete carious tissue removal

Pulp exposure during caries removal · Children (3-11 years) with symptomless, vital dentine caries in primary molars

Partial caries removal reduced the reported risk of pulp exposure versus complete caries removal in primary teeth (RR 0.24; ungraded).

Food marketing exposure or greater marketing power vs No, less, or less powerful food marketing

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

Across five studies, 40% showed any association of potential public health harm for food purchasing (very low certainty).

Probing pocket depth (PPD/PD) · People with diabetes mellitus (type 1 or type 2, mostly type 2) and periodontitis, at least 16 years of age

Periodontal treatment (subgingival instrumentation, with or without… led to lower probing pocket depth (PPD/PD) compared with no active intervention/usual care; GRADE not reported.

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

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

Two RCTs suggest responsive complementary feeding leads to better weight gain in the first two years, though effects were small and not always sustained (ungraded).
