Oral-health promotion programs (OHPPs): community-based oral-health education/training, supervised toothbrushing with fluoride toothpaste and topical fluoride, dental screening, and dietary advice vs No oral health promotion program

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

Oral health promotion programs have a positive effect on OHRQoL in adolescents (narrative synthesis; low methodological quality of included evidence; no pooled estimate or GRADE rating).

2 findings from 1 review

Theory-based oral health education/promotion interventions (HBM, TPB, SCT, HAPA, TTM, PMT, SOC, PRECEDE-PROCEED, MI) vs Control (waitlist, routine/standard oral health education, or minimal intervention)

Oral health-related quality of life · school‐age children and adolescents

Theory-based interventions significantly improved oral health-related quality of life (SMD 7.38; low certainty), with very high heterogeneity.

Dental (tooth) agenesis vs No dental agenesis

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

The umbrella review reported insufficient scientific evidence to support an association between dental agenesis and oral health-related quality of life.

2 findings from 1 review

Older age vs Younger adults (population mean age <=33.4 years)

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

The abstract reports older age is associated with worse OHRQoL, but the body notes the evidence on age is limited and conflicting (narrative synthesis; no pooled estimate or GRADE rating).

2 findings from 1 review

Female sex vs Male sex

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

The abstract reports female sex is associated with worse OHRQoL, but the conclusion states the impact of gender was not clarified (narrative synthesis; no pooled estimate or GRADE rating).

2 findings from 1 review

Bruxism vs No bruxism

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

Bruxism was not shown to impact OHRQoL in adolescents (narrative synthesis; no pooled estimate or GRADE rating).

2 findings from 1 review

Dental erosion vs No dental erosion

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

The umbrella review reported that dental erosion has not been shown to affect oral health-related quality of life.

2 findings from 1 review

Favorable socioeconomic and family environment vs Less favorable socioeconomic and family environment

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

The umbrella review reported better oral health-related quality of life with favorable housing, parental education, income, family environment, and access to dental care.

1 finding from 1 review

Temporomandibular disorder vs No temporomandibular disorder

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

Temporomandibular disorder is associated with worse OHRQoL in adolescents (narrative synthesis; no pooled estimate or GRADE rating).

2 findings from 1 review

Atraumatic restorative treatment vs placebo

Oral health-related quality of life · Children with dental caries

ART and placebo did not differ for oral health-related quality of life, based on an indirect network estimate with no direct trials (MD -0.01, 95% CI -0.40 to 0.38; ungraded).
