Fluoride mouthrinse (0.05-0.32% sodium fluoride or amine fluoride) added to daily fluoride toothpaste vs Control: fluoride toothpaste alone, placebo mouthrinse + toothpaste, or non-fluoride (chlorhexidine) mouthrinse + toothpaste

Incidence of initial enamel caries / white spot lesions adjacent to bracket base (subject level, dichotomized) · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)

Adding a fluoride mouthrinse to daily fluoride toothpaste produced a small reduction in the incidence of initial caries/white spot lesions adjacent to brackets (pooled risk difference -0.07, 95% CI -0.14 to -0.01; 5 studies, 491 subjects), but the authors judged the overall evidence inconclusive (ungraded).

Fluoride mouthrinse (0.05-0.32% sodium fluoride or amine fluoride) added to daily fluoride toothpaste vs Control: fluoride toothpaste alone, placebo mouthrinse + toothpaste, or non-fluoride (chlorhexidine) mouthrinse + toothpaste

Side effects or other adverse events · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)

No adverse effects were reported in any of the seven included studies (ungraded).

Acidic bacillary pH on teeth vs Non-acidic bacillary pH

Dental caries · Primary school children in Ethiopia

Acidic bacillary pH on the teeth was associated with higher odds of dental caries (OR 2.42, 95% CI 1.494-3.335; ungraded).

Slum / urban-disadvantaged setting vs Non-slum urban / general-urban / national population

Ever utilised dental services · Adult residents of slums and non-slum urban settings of LMICs

Ever-use of dental services is low-to-moderate (17%-71%) and generally lower in slum/rural groups; ungraded.

Poor / no tooth brushing habit vs Good tooth brushing habit

Dental caries · Primary school children in Ethiopia

A poor tooth-cleaning habit was associated with higher odds of dental caries (OR 3.90, 95% CI 2.761-5.045; ungraded).

Slum / urban-disadvantaged setting vs Non-slum urban setting

Determinants of oral diseases · Adult residents of slums and non-slum urban settings of LMICs

Older age, lower education and income, poor oral hygiene, and disadvantaged residential setting were associated with oral diseases; directions varied across studies.

Slum residence vs Non-slum urban setting

Dental caries · Adult residents of slums and non-slum urban settings of LMICs

Slum residents had non-significantly higher odds of caries than non-slum residents (OR 1.21, 95% CI 0.94-1.56; single study); ungraded.

Er:YAG laser irradiation of sound enamel before acid challenge vs No anticaries intervention (untreated enamel)

Demineralised lesion depth · Human tooth enamel specimens, sound/intact (in vitro)

Er:YAG laser irradiation significantly reduced demineralised lesion depth versus untreated control (SMD -0.55, 95% CI -0.97 to -0.12; 3 in vitro studies, I2=62%; ungraded).

Significant salivary microbial (Lactobacillus) load vs No/low significant microbial load

Dental caries · Primary school children in Ethiopia

A significant salivary microbial (Lactobacillus) load was associated with higher odds of dental caries (OR 3.82, 95% CI 3.439-4.192; ungraded).

Slum residence vs Non-slum urban setting

Periodontal pocket (odds), slum vs non-slum residence · Adult residents of slums and non-slum urban settings of LMICs

Slum residents had significantly higher odds of periodontal pocketing than non-slum residents (OR 1.50, 95% CI 1.13-1.98; single study); ungraded.

Male sex vs Female sex

Dental caries susceptibility · Institutionalized orphan children (roughly 3 to 18 years)

Male institutionalized children had a marginally higher caries risk than females (RR 1.02), a non-significant difference (very low certainty).
