In one RCT, preformed metal crowns had an annual failure rate of 2.5% after 2 years.
1 finding from 1 review
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).

Restoration failure · Children with carious primary teeth
No comparative effect estimate was reported; the review reports this three-arm comparison but tabulates only compomer failure.

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).

Continued root formation / root development · Patients with carious pulp exposure in permanent teeth (predominantly immature) undergoing DPC or pulpotomy
Evidence on continued root formation for calcium hydroxide versus MTA is weak and inconclusive (3 RCTs, not pooled; ungraded).

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years
RMGIC had an annual failure rate of 1.9-16.9% (4 RCTs), lower than amalgam and similar to compomer/composite; low quality of evidence (ungraded).

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).

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).

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).

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).

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years
Conventional GIC had an annual failure rate of 7.6-16.6% (2 RCTs) and failed more than amalgam in one trial; low quality of evidence (ungraded).

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).
