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).
