Class-I (single-surface) cavity restoration vs Class-II (proximal/multi-surface) cavity restoration

Treatment failure (annual failure rate) by cavity class · Children with carious primary teeth restored in Class-I versus Class-II cavities, no pulp therapy

Class-II restorations failed more than Class-I (annual failure 5-28.9% vs 1.2-14.7% in ART studies); low quality of evidence (ungraded).

Tempered chlorhexidine vs Non-tempered chlorhexidine

Reduction in level of contamination by particles >5 um (droplets) at <2 m from patient's oral cavity · Dental patients undergoing aerosol-generating procedures (AGPs) and the dental healthcare providers treating them

It is very uncertain whether tempered chlorhexidine changes reduction in level of contamination by particles >5 um (droplets) at… compared with non-tempered chlorhexidine (very low certainty).

Single-visit root canal treatment vs Multiple-visit root canal treatment (two or more visits)

Pain at 12 months or more (long-term postobturation pain) · People aged 10 years or above requiring root canal treatment; permanent teeth with completely formed apex and without internal resorption

Artemisia desertorum spreng (Yunnan) vs placebo

Presence of dry socket · Adults (>18 years) having permanent tooth extraction (predominantly mandibular third molars)

Artemisia desertorum spreng (Yunnan) showed no clear difference in presence of dry socket compared with placebo; GRADE not reported.

Genetically predicted gene expression (TWAS; S-PrediXcan with GTEx v8 cis-eQTL across 49 tissues; cross-tissue S-MultiXcan) vs ECC-unaffected children (association of genetically predicted expression)

Early childhood caries (ECC) - association with genetically predicted expression of LACC1 (chr13q14.11) · Children up to age 5-6 years (European / European non-Hispanic ancestry); 843 ECC-affected vs 2124 unaffected across 5 cohorts (N=2974)

Genetically predicted LACC1 expression reached the TWAS threshold for ECC (p = 3.98e-5) but was flagged as a possible false positive (LD misspecification) and not further considered; ungraded.

Periodontal treatment: scaling and root planing (SRP) plus advice vs Community care: advice only

Adverse events due to periodontal therapy · Patients with cardiovascular disease and chronic periodontitis
1 finding from 1 review

Pulpotomy with Biodentine vs Pulpotomy with mineral trioxide aggregate (MTA)

Overall success (composite of clinical and radiographic success) · Human permanent teeth with irreversible pulpitis due to carious pulp exposure

Biodentine had a significantly higher pulpotomy success rate than MTA (indirect comparison; numeric estimate not available); ungraded.

Hall technique vs Compomer restoration or non-restorative caries treatment

Treatment failure (annual failure rate) · Children (aged 3-8 years) with 2-surface occluso-proximal dentine caries in primary molars, no pulp therapy

Preformed metal (Hall) crowns had a low reported annual failure rate (3.1%) versus compomer (14.7%) in one RCT; low quality of evidence (ungraded).

Genetically predicted gene expression (TWAS; S-PrediXcan with GTEx v8 cis-eQTL across 49 tissues; cross-tissue S-MultiXcan) vs ECC-unaffected children (association of genetically predicted expression)

Early childhood caries (ECC) - association with genetically predicted expression of NRAD1 (LINC00284) (chr13q14.11) · Children up to age 5-6 years (European / European non-Hispanic ancestry); 843 ECC-affected vs 2124 unaffected across 5 cohorts (N=2974)

Genetically predicted NRAD1 (LINC00284) expression reached the TWAS threshold for ECC (p = 1.69e-6) but was flagged as a possible false positive (LD misspecification) and not further considered; ungraded.

Chlorhexidine 0.2% socket irrigation (monoject syringe) vs Chlorhexidine 0.2% mouthrinse

Presence of dry socket · Adults (>18 years) having permanent tooth extraction (predominantly mandibular third molars)

Chlorhexidine 0.2% socket irrigation (monoject syringe) led to lower presence of dry socket compared with chlorhexidine 0.2% mouthrinse; GRADE not reported.

Silver diamine fluoride (SDF; 30% or 38%) vs Atraumatic restorative treatment (ART)

Caries arrest · Children (age 1-10 years) with active cavitated dentin caries lesions in primary molars

SDF was not significantly better than ART at arresting caries (pooled ES 0.05, 95% CI -0.42 to 0.51; ungraded).

Genetically predicted gene expression (TWAS; S-PrediXcan with GTEx v8 cis-eQTL across 49 tissues; cross-tissue S-MultiXcan) vs ECC-unaffected children (association of genetically predicted expression)

Early childhood caries (ECC) - association with genetically predicted expression of TAS2R31 (chr12p13.2) · Children up to age 5-6 years (European / European non-Hispanic ancestry); 843 ECC-affected vs 2124 unaffected across 5 cohorts (N=2974)

Genetically predicted expression of TAS2R31 was suggestively associated with ECC in the TWAS (p = 1.04e-5); genetic association, ungraded.

Composite resin vs Compomer, glass-ionomer/RMGIC, amalgam, or glass carbomer

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years

Composite resin (hybrid 0-19.5%; bulk-fill 0-16.9%) performed comparably to or better than most alternatives across 11 RCTs; evidence is of low to unclear quality (ungraded).
