Calcium hydroxide (CH) vs Mineral trioxide aggregate (MTA)

Dentin bridge formation · Patients with carious pulp exposure in permanent teeth undergoing partial pulpotomy

Evidence on dentin bridge formation for calcium hydroxide versus MTA is weak and imprecise, with no material shown superior (4 RCTs, not pooled; ungraded).

Calcium hydroxide (CH) vs Mineral trioxide aggregate (MTA)

Overall success (composite of clinical and radiographic success) · Patients with carious pulp exposure in immature permanent teeth

In immature teeth, the effect of MTA versus calcium hydroxide on success is very uncertain (OR 2.22, 95% CI 0.13-36.67; very low certainty).

Calcium hydroxide (CH) vs Mineral trioxide aggregate (MTA)

Overall success (composite of clinical and radiographic success) · Patients with carious pulp exposure in permanent teeth undergoing direct pulp capping

For direct pulp capping, MTA probably achieves higher clinical and radiographic success than calcium hydroxide (OR 3.10, 95% CI 1.66-5.79; moderate certainty).

Gum chewing (sugar-free) vs No chewing gum

Self-reported thirst · Elderly (>60 years) and medically compromised adults with xerostomia / dry mouth

Gum chewing reduced self-reported thirst in most studies (6 of 7 positive, 1 no effect); not meta-analyzed.

Chlorhexidine mouthwash vs Blank control

Plaque · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)

Chlorhexidine mouthwash may reduce the Plaque Index versus blank control in the short term (WMD -0.70, 95% CI -1.12 to -0.27), but the evidence is very uncertain (very low certainty).

Periodontal disease assessed by loss of attachment (LOA / clinical attachment loss) vs Individuals without periodontal disease (by LOA)

Oral health-related quality of life · Indian adults and elderly (general, police, teachers, institutionalised)

No difference in OHRQoL was seen between groups for periodontal disease by LOA on OHIP-14/OIDP (pooled SMD -0.04, CI includes 0); ungraded.

Cetylpyridinium chloride mouthwash vs Blank control

Plaque · Orthodontic patients (any age) undergoing orthodontic treatment (mostly fixed appliances)

CPC mouthwash may reduce plaque-related indexes versus blank control in the short term, but the evidence is very uncertain (very low certainty).

Self-assembling peptide P11-4 vs Placebo or no active treatment

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 significantly improved remineralization versus control (SMD -0.56, 95% CI -0.96 to -0.15); certainty of evidence not assessed (no GRADE).

Compomer (Dyract) vs Resin-modified glass ionomer cement (RMGIC)

Secondary caries · Patients requiring dental restoration; deciduous (primary) teeth

Over 2 or more years in deciduous teeth, secondary caries did not differ significantly between compomer and RMGIC (RR 1.68, 95% CI 0.87-3.25; low certainty).

Herbal mouthwash vs placebo

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

Herbal mouthwash reduced Mutans streptococci versus placebo, but certainty is very low.

Gum chewing (sugar-free) vs No chewing gum

Salivary flow rate · Elderly (>60 years) and medically compromised adults with xerostomia / dry mouth

Across 19 studies the effect of gum chewing on stimulated and/or unstimulated salivary flow rate was mixed (9 positive, 10 no effect); this broad outcome was not meta-analyzed.

P11-4 + fluoride varnish vs Fluoride varnish

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…

P11-4 plus fluoride varnish was significantly better than fluoride varnish alone (SMD -0.71, 95% CI -1.13 to -0.29); certainty of evidence not assessed (no GRADE).

Vitamin D deficiency (serum 25(OH)D < 50 nmol/L) vs Normal vitamin D level (serum 25(OH)D ≥ 50 nmol/L)

Dental caries · Children (<19 years)

Children with vitamin D deficiency had a 22% higher risk of dental caries than those with normal vitamin D levels (unadjusted RR 1.22; ungraded).

Intraglandular botulinum neurotoxin (BoNT) injection vs placebo injection

Reduction in frequency and severity of drooling · Adults with Parkinson's disease and sialorrhea (drooling)

Type A botulinum toxin significantly reduced DSFS scores versus placebo (SMD -0.80, 95% CI -1.25 to -0.36; ungraded subgroup).

Vitamin D deficiency (serum 25(OH)D < 50 nmol/L) vs Normal vitamin D level (serum 25(OH)D ≥ 50 nmol/L)

Dental caries · Children with permanent dentition (>12 years)

In children with permanent dentition, vitamin D deficiency was associated with a 28% higher caries risk (RR 1.28; ungraded).

Calcium hydroxide (CH) vs Mineral trioxide aggregate (MTA)

Overall success (composite of clinical and radiographic success) · Patients with carious pulp exposure in permanent teeth of mixed/unspecified root maturation

In mixed-maturation teeth, the effect of MTA versus calcium hydroxide on success is very uncertain (OR 1.11, 95% CI 0.17-7.11; very low certainty).
