Strategies to integrate oral health into primary care (e.g., training/education of non-dental primary care professionals, policy/financing and health-insurance changes, colocation of dental and medical services, interprofessional and community-health-worker collaboration, teledentistry, integrated oral health assessment tools, school-based activities) vs No integration / usual care (or pre-integration baseline; many included studies uncontrolled)

Oral disease outcomes, including dental caries estimates · People of all ages and abilities served through primary care and related settings (children, pregnant women, older adults in…

Most studies reported improved oral disease outcomes with integration strategies (8 of 9 studies improved, 1 no change; 9 studies, narrative synthesis; ungraded).

  • Strategies to integrate oral health into primary care: a systematic review. 2023 All outcomes
    Primary care, community, school, and aged-care/residential/nursing-home settings
    Nine studies reported oral disease outcomes, seven of which measured change in dental caries estimates. Eight of the nine studies reported improved oral disease outcomes; one (Vichayanrat 2012) reported no change in…

Self-assembling peptide P11-4 vs CPP-ACFP

Remineralization / reduction in lesion severity (change in QLF, laser fluorescence, or lesion area) · Patients with white spot lesions / early caries lesions (WSLs/ECLs), including orthodontic and non-orthodontic lesions, active caries…

Self-assembling peptide P11-4 did not differ significantly from CPP-ACFP (SMD -0.13, 95% CI -0.68 to 0.42); certainty of evidence not assessed (no GRADE).

Herbal mouthwash vs Blank control

Gingival inflammation-related index · People undergoing orthodontic treatment (any age; 9 to 34 years in included studies)

Herbal mouthwash reduced some gingival inflammation-related indices, but certainty is very low.

Herbal mouthwash vs Blank control

Cariogenic bacteria (Mutans streptococci) · People undergoing orthodontic treatment (any age; 9 to 34 years in included studies)

Herbal mouthwash showed mixed effects on Mutans streptococci, with very low-certainty evidence.

Mutans streptococci detected in plaque or saliva at baseline vs No mutans streptococci detected in plaque or saliva 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)

Across the sample-based sensitivity analysis, mutans streptococci at baseline were associated with higher odds of developing caries.

Skin color / ethnicity vs Reference skin color / ethnicity

Oral health-related quality of life · Adolescents (10-19 years)

There is no concrete evidence on the impact of skin color/ethnicity on OHRQoL in adolescents (evidence gap; narrative synthesis; no pooled estimate or GRADE rating).

  • Oral-health-related quality of life in adolescents: umbrella review. 2023 All outcomes
    Community/school/clinic settings; adolescents 10-19 years; included reviews conducted in multiple countries
    Biological data such as skin color and age have no concrete evidence about this impact in the OHRQoL. Important aspects like gender and skin color did not have their level of impact clarified.

Fluoride toothpaste vs Not applicable (single-group prevalence)

Fluoride toothpaste use prevalence (among children with caries) · Children with dental caries (deciduous and/or permanent dentition) in low- and middle-income countries

About 39% of children with caries in LMICs used fluoride toothpaste (pooled prevalence 0.391, 95% CI 0.166 to 0.644; 2 studies; not GRADE-rated).

Resin infiltration vs Baseline before resin infiltration

Lightness change · Patients with post-orthodontic white spot lesions and permanent dentition

Knosel (2019) reported a statistically significant lightness-change effect.

Antiretroviral therapy (any, including cART) vs No antiretroviral medication (treatment-naive)

Salivary immunoglobulin A (SIgA) concentration · Children and adolescents (<18 years) living with HIV (CLWH)

Evidence on salivary IgA in CLWH on versus off ART was divergent and inconclusive (very low certainty).

Selective caries removal (SCR) + composite resin vs Complete caries removal (CCR) + composite resin

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

In one RCT, selective caries removal had a 3.44 higher probability of failure than complete caries removal.

Visual caries detection (ICDAS visual/visual-tactile inspection) vs Reference standard (histology, excavation, or enhanced visual examination)

Sensitivity for detection of enamel caries · Asymptomatic children or adults suspected of enamel caries (clinical studies); extracted teeth (in vitro studies)

In the fully within-person analysis, visual classification had a summary sensitivity of 0.82 (95% CrI 0.73, 0.89); ungraded.

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).
