Silver diamine fluoride (SDF) vs placebo or no treatment

Secondary prevention of caries · Children and adults (with or without carious lesions)

The review found no eligible studies for this question.

3 findings from 1 review

Silver diamine fluoride (SDF) vs Nano-silver fluoride (NSF; with or without green tea extract)

Caries arrestment at the surface level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

In one trial, nano-silver fluoride arrested more surfaces than SDF (OR 0.52 favoring the comparator; ungraded subgroup).

Cranberry extract / juice and proanthocyanidin (flavonoid) fractions vs Untreated or vehicle control (some studies vs positive antimicrobial controls, e.g. chlorhexidine/fluoride)

pH drop / acidogenicity buffering · Streptococcus mutans (in vitro cultures and biofilms)

Cranberry extract reduces S. mutans acidogenicity / glycolytic pH drop in vitro (5 studies; ungraded).

Silver diamine fluoride (SDF) vs Fluoride varnish

Dental pain or sensitivity · Children and adults (with or without carious lesions)

It is very uncertain whether silver diamine fluoride (SDF) changes dental pain or sensitivity compared with fluoride varnish (very low certainty).

1 finding from 1 review

Fluoride toothpaste less than 1000 ppm (lower concentration) vs Fluoride toothpaste 1000 ppm or more (higher concentration)

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).

High intake of sweets vs Lower/less intake of sweets

Dental caries · Primary school children in Ethiopia

A high intake of sweets was associated with higher odds of dental caries (OR 2.71, 95% CI 1.968-3.451; ungraded).

1 finding from 1 review

Grape seed extract (GSE) and its proanthocyanidin fractions vs Untreated or vehicle control (some studies vs positive antimicrobial controls, e.g. chlorhexidine/fluoride)

Gtf activity · Streptococcus mutans (in vitro cultures and biofilms)

One study reported grape seed extract inhibits S. mutans Gtf activity (ungraded).

1 finding from 1 review

Surgical miniplates with facemask vs Surgical miniplates with Class III elastics

Overjet · Children and adolescents (aged 16 years or younger) with prominent lower front teeth (Class III malocclusion)

Surgical miniplates with facemask showed no clear difference in overjet compared with surgical miniplates with Class III elastics; GRADE not reported.

1 finding from 1 review

Fluoride-releasing primers/adhesives (Opal Seal; Clearfil Protect Bond) vs Conventional/control orthodontic adhesive (e.g., Transbond XT) or negative control

Enamel demineralization (DIAGNOdent score) · Patients undergoing fixed orthodontic (fixed appliance) treatment (adolescents and adults, ages 12 to 35)

Across three small non-randomized studies, fluoride-releasing primers (Opal Seal, Clearfil) showed no consistent clinical advantage over conventional primers in preventing white spot lesions (ungraded).

1 finding from 1 review

Orthodontic adhesive containing quaternary ammonium resin monomer + 40% n-ACP vs Conventional/control orthodontic adhesive (e.g., Transbond XT) or negative control

Calcium and phosphate ion release · Human enamel specimens around orthodontic brackets (in vitro)

In vitro, an n-ACP-containing adhesive significantly increased calcium and phosphate ion release up to 42 days in a single study (ungraded).

1 finding from 1 review

Higher number of lost teeth (per one additional lost tooth) vs One fewer missing tooth

Malignant transformation (oral cancer development) · Adults in case-control studies (oral cancer patients vs healthy controls)

The number of missing teeth (per tooth) was not significantly associated with oral cancer (OR 0.96, 95% CI 0.92-1.01); ungraded.

1 finding from 1 review

Pentoxifylline vs Placebo or no active treatment

Difficulty in speech (participant-reported proxy) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

Pentoxifylline led to lower difficulty in speech (participant-reported proxy) compared with placebo or no active treatment; GRADE not reported.

1 finding from 1 review

Started toothbrushing with fluoride toothpaste before 24 months (earlier start) vs Started after 24 months (later start)

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 started toothbrushing with fluoride toothpaste before 24 months… changes fluorosis (percentage prevalence in permanent teeth) compared with started after 24 months (later start) (very low certainty).

1 finding from 1 review

Grape seed extract (GSE) and its proanthocyanidin fractions vs Untreated or vehicle control (some studies vs positive antimicrobial controls, e.g. chlorhexidine/fluoride)

Antioxidant capacity · Streptococcus mutans (in vitro cultures and biofilms)

One study reported high antioxidant capacity of grape seed extract (ungraded).

1 finding from 1 review

Breastfeeding <18 months vs Breastfeeding for ≥18 months

Early childhood caries (ECC) · Preschool children (<6 years)

Breastfeeding for <18 vs ≥18 months was associated with significantly fewer caries (RR 0.41, 95% CI 0.18-0.92; substantial heterogeneity; ungraded).
