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).

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).
