Oral health-related quality of life · people aged 60 years and older living in the community
Lower out-of-pocket health expenditure was associated with better OHRQoL (83.9, 95% CI 75.2 to 92.6 vs 67.5, 95% CI 58.5 to 76.5); the difference was statistically significant (ungraded).

Oral health-related quality of life · people aged 60 years and older living in the community
Lower country-level dental caries prevalence was associated with better OHRQoL (low-prevalence pooled mean 81.5, 95% CI 76.5 to 86.6, higher than high-prevalence countries); statistically significant (ungraded).

Fluorosis (percentage prevalence in permanent teeth) · Children exposed to topical fluoride when under 6 years old; fluorosis assessed in permanent teeth at 6 to 18 years
It is very uncertain whether fluoride toothpaste less than 1000 ppm (lower concentration) changes fluorosis (percentage prevalence in permanent teeth) compared with fluoride toothpaste 1000 ppm or more (higher concentration) (very low certainty).

Enamel resistance to demineralization (microhardness / lesion depth) · Human enamel adjacent to restorations or in pits and fissures (in situ / ex vivo)
Er:YAG laser showed a mixed and limited effect on enamel resistance to demineralization: feasible for controlling progression around restorations but not preventing caries formation, and ineffective in pits and fissures (ungraded, 2 ex-vivo studies, no pooled estimate).

Determinants of oral diseases · Adult residents of slums and non-slum urban settings of LMICs
Age, education, income, oral-hygiene behaviour, dental-visit pattern and slum/disadvantaged residence are associated with oral disease; gender effects are disease-specific; ungraded.
1 finding from 1 review
Fourteen studies reported determinants: older age, less education, lower income, poor oral hygiene behaviour (brushing frequency, technique), infrequent dental visits and disadvantaged/slum residential setting were…

Fluorosis (percentage prevalence in permanent teeth) · Children exposed to topical fluoride when under 6 years old; fluorosis assessed in permanent teeth at 6 to 18 years
Fluoride toothpaste 440 ppm (lower concentration) probably leads to lower fluorosis (percentage prevalence in permanent teeth) compared with fluoride toothpaste 1450 ppm (higher concentration) (moderate certainty).

Fluorosis (percentage prevalence in permanent teeth) · Children exposed to topical fluoride when under 6 years old; fluorosis assessed in permanent teeth at 6 to 18 years
Fluoride toothpaste 550 ppm (lower concentration) probably leads to lower fluorosis (percentage prevalence in permanent teeth) compared with fluoride toothpaste 1000 ppm (higher concentration) (moderate certainty).

White spot lesion incidence · High caries-risk patients: fixed-orthodontic-appliance patients and children with partially erupted permanent molars
Low-power CO2 laser (LLLT) is associated with a lower incidence of new white spot lesions than placebo (OR 0.21, CI 0.15 to 0.30; ungraded, 3 RCTs, considerable heterogeneity I2=71%).

Early childhood caries (ECC) · Healthy children under 6 years in South Africa
Parental tertiary education (vs high-school education) was associated with about 1.8 times higher odds of early childhood caries in South Africa (OR 1.77, 95% CI 1.22-2.57; 2 studies; not GRADE-rated).

Dental caries · Healthy children and adolescents in the United Arab Emirates
The association between parental education and caries was inconsistent; father's (but not consistently mother's) education was inversely associated with caries in some studies (narrative synthesis; not GRADE-rated).
1 finding from 1 review
Maternal education was not associated with children's caries in the Hashim et al. studies, whereas father's educational level was negatively associated with DMFT in Khadri et al. (secondary-aged children: -0.35, 95% CI…

Dental caries · Healthy children and adolescents in the United Arab Emirates
Evidence on socioeconomic status/income and caries was inconsistent: some studies linked lower income to higher caries while others found no association (narrative synthesis; not GRADE-rated).
1 finding from 1 review
Findings were contradictory. Hashim et al. found children from low-income families had higher odds of severe early childhood caries (OR 1.43, 95% CI 1.11-1.85), and Ahmad et al. reported significantly higher DMFT in…
