Composite resin vs Light-cured compomer (polyacid-modified composite resin)

Restoration failure · Children with carious primary teeth after vital or non-vital pulp therapy

In one RCT, composite resin had an annual failure rate of 0% after 2 years.

1 finding from 1 review

Composite resin with etch-and-rinse (total-etch) adhesion vs Composite resin with self-etch adhesion (same universal adhesive)

Treatment failure (annual failure rate) · Children with moderately deep dentine caries in primary molars, no pulp therapy

Etch-and-rinse adhesion failed more than self-etch (19.5% vs 7.0% annual failure) in one RCT; low quality of evidence (ungraded).

Amalgam restoration vs Composite resin, compomer, conventional glass-ionomer cement, or resin-modified GIC (head-to-head RCT comparators)

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

Amalgam restorations in primary teeth showed a wide annual failure rate (1-28%) across 4 RCTs; the evidence is of low quality (high risk of bias; ungraded).

Composite strip crown (CSC) with a post (microhybrid composite resin, Amelogen) vs Post type: composite post (CP) vs fibre post (FP) vs reverse metal post (RMP)

Treatment failure (annual failure rate) · Children with severely decayed maxillary primary incisors treated by pulpectomy (non-vital pulp therapy)

Composite strip crowns with composite posts had a low annual failure rate (2.3%) in maxillary primary incisors after pulpectomy (single high-risk-of-bias RCT; low quality of evidence; not GRADE-rated).

High-viscosity glass-ionomer cement (HVGIC) restoration (conventional restorative approach) vs Compomer, composite resin, or another HVGIC

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

High-viscosity GIC had a wide annual failure rate (2.9-25.6%) and was outperformed by compomer/composite in some trials (3 RCTs); low quality of evidence (ungraded).

Selective caries removal (SCR) + composite resin vs Complete caries removal (CCR) + composite resin

Treatment failure (annual failure rate) · Children with deep dentine caries in primary molars restored with composite resin (indirect pulp treatment; pulpotomy only if pulp exposed…

Complete caries removal with composite resin had an annual failure rate of 6.8% in primary molars (single high-risk-of-bias RCT; low quality of evidence; not GRADE-rated).

Preformed metal crown (PMC) vs Resin-modified glass-ionomer cement + composite resin (modified open-sandwich restoration)

Restoration failure · Children with carious primary teeth after vital or non-vital pulp therapy

In one RCT, preformed metal crowns had an annual failure rate of 2.5% after 2 years.

1 finding from 1 review

Composite resin with a beveled cavity margin vs Composite resin with no bevel (butt-joint margin)

Treatment failure (annual failure rate) · Children with Class-I carious lesions in primary molars, no pulp therapy

A beveled margin lowered composite resin failure (1.8% vs 3.5% annual failure) in one RCT; low quality of evidence (ungraded).

Restorative materials placed by atraumatic restorative treatment (ART); mostly high-viscosity/conventional GIC, also RMGIC, glass carbomer, compomer, composite resin vs Different ART materials or application techniques (e.g., bilayer vs single-step, with vs without cavity conditioner/disinfectant), or composite resin

Treatment failure (annual failure rate) · Children with carious primary teeth treated by atraumatic restorative treatment (hand-instrument caries removal), no pulp therapy

ART restorations (mainly GIC) had a wide annual failure rate (1.2-37.1%) across 10 RCTs, with technique affecting survival; low to unclear quality of evidence (ungraded).

1 finding from 1 review

Preformed metal crown (PMC) vs Resin-modified glass-ionomer cement + composite resin (modified open-sandwich restoration)

Treatment failure (annual failure rate) · Children with carious primary molars treated by pulpotomy (vital pulp therapy)

Preformed metal crowns had a low annual failure rate (2.5%) in primary molars after pulpotomy, but the evidence is of low quality (single high-risk-of-bias split-mouth RCT; not GRADE-rated).

2 findings from 1 review

Bulk-fill composite resin with 7-second dentine etching vs Bulk-fill composite resin with 15-second dentine etching

Treatment failure (annual failure rate) · Children (aged 5-8 years) with Class-II caries in primary molars, no pulp therapy

Etching dentine for 7 s rather than 15 s lowered bulk-fill composite failure (5.8% vs 16.9% annual failure) in one RCT; low quality of evidence (ungraded).

1 finding from 1 review

Metal-free single crowns (full-contour zirconia) vs Composite strip crown

Treatment failure (annual failure rate) · Children (aged 3-5.5 years) with early childhood caries in anterior primary teeth (>=2 carious surfaces), no pulp therapy

Zirconia crowns failed less than composite strip crowns (3.3% vs 15% annual failure) in one RCT; low quality of evidence (ungraded).

1 finding from 1 review

Bio-active restorative materials vs Any conventional restorative material

Treatment failure (planned; no eligible studies) · Children with carious primary teeth after vital or non-vital pulp therapy

No eligible studies were found evaluating bio-active restorative materials for restoring carious primary teeth after pulp therapy.

1 finding from 1 review

Metal-reinforced glass-ionomer cement (MRGIC) restoration vs Conventional GIC

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

Metal-reinforced GIC had a high annual failure rate (29.9%) in a single RCT; low quality of evidence (ungraded).

1 finding from 1 review

Compomer (C) vs Amalgam, RMGIC, HVGIC, composite resin, bulk-fill composite resin, another compomer, or alternative caries management

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

Compomer had an annual failure rate of 0-14.7% (7 RCTs), comparable to amalgam/RMGIC/composite and better than high-viscosity GIC; low quality of evidence (ungraded).
