Community and caregiver oral health education plus media campaign vs Pre-intervention BBTD rate

Baby bottle tooth decay prevalence · Alaska Native and American Indian Head Start children

High-intensity community education was associated with a 33% reduction in BBTD prevalence, without a GRADE rating.

Community and caregiver oral health education plus media campaign vs Pre-intervention BBTD rate

Baby bottle tooth decay prevalence · Alaska Native Head Start children

The Alaska Native site had a 20% increase in BBTD prevalence, without a GRADE rating.

Presence of oral Candida albicans vs Absence of oral Candida albicans

Early childhood caries (ECC) · Children aged ≤6 years (early childhood)

RETRACTED. Among studies before 2017, oral C. albicans presence was associated with higher odds of ECC (OR 4.89, 95% CI 2.79-8.58); ungraded subgroup from a retracted review.

Er:YAG laser preparation combined with acid-etching vs Acid-etching (phosphoric acid)

Sealant retention rate (completely retained) · Children with permanent molars requiring pit-and-fissure sealants

At 12 months, Er:YAG laser combined with acid-etching significantly improved sealant retention versus acid-etching alone (OR 0.39, 95% CI 0.19 to 0.80, favouring laser+acid; ungraded, single study).

Er:YAG laser preparation combined with acid-etching vs Acid-etching (phosphoric acid)

Physiological stress indicators (heart rate, oxygen saturation) · Children (ages 6-12) receiving pit-and-fissure sealants

Heart rate and oxygen saturation did not differ significantly between laser-plus-acid and acid-etching (ungraded, single study).

Er:YAG laser preparation combined with acid-etching vs Acid-etching (phosphoric acid)

Development of >=1 new carious lesion (caries incidence) · Children (high caries risk) with permanent molars requiring pit-and-fissure sealants

Caries incidence was 10% with laser-plus-acid versus 22% with acid-etching at 18 months, a non-significant difference (ungraded, single study).

Er:YAG laser preparation combined with acid-etching vs Acid-etching (phosphoric acid)

Dental anxiety (subjective and objective scores) · Children (ages 6-12) receiving pit-and-fissure sealants

Er:YAG laser preparation added to acid-etching did not increase children's dental anxiety versus acid-etching alone (P > 0.05; ungraded, single study).

Mutans streptococci present in oral samples at baseline vs Mutans streptococci absent in oral samples at baseline

Development of any (cavitated or non-cavitated) carious lesion · Children younger than 6 years with caries-free primary dentition (no cavitated or non-cavitated lesions at baseline)

Preschool children with mutans streptococci at baseline probably have about four times higher odds of developing early childhood caries (OR 4.13; moderate certainty).

Mutans streptococci present in oral samples at baseline vs Mutans streptococci absent in oral samples at baseline

Future caries experience (dmft/dmfs) · Children younger than 6 years with caries-free primary dentition (no cavitated or non-cavitated lesions at baseline)

Children with mutans streptococci at baseline had a greater future caries experience (SMD 0.85, a large effect; ungraded).

Hall technique vs Non-restorative caries treatment

Discomfort associated with the procedure · Children with decayed primary molar teeth

It is very uncertain whether preformed metal crown (fitted using the Hall Technique) changes discomfort associated with the procedure compared with non-restorative caries treatment (very low certainty).

Hall technique vs Non-restorative caries treatment

Adverse events: gingival bleeding · Children with decayed primary molar teeth

It is very uncertain whether preformed metal crown (fitted using the Hall Technique) changes adverse events: gingival bleeding compared with non-restorative caries treatment (very low certainty).

  • Preformed crowns for decayed primary molar teeth 2015 · Cochrane All outcomes
    Six months and four years
    Bone resorption: one case at six months in a tooth treated with a veneer crown; no bone resorption at either the veneer crown or stainless steel sites at four-year follow-up (Analysis 3.2).

    At six months, none (0/11) of the PMC sites had gingival bleeding, but all (11/11) veneer sites had bleeding, 10 of which bled on probing; statistically significant (McNemar's test, P < 0.001). At four years, one case…

Simple childhood caries prediction models with at least two predictors vs No competing model

Dental caries discrimination (area under the curve) · Children or adolescents

The Luo (2021) model had an AUC of 0.77 (95% CI 0.76 to 0.77).
