Table 1 Outcome criteria for the clinical and radiographic assessment of restorations and teeth

	Control restoration	Hall PMCs
Successful	restoration appears satisfactory, no intervention required no clinical signs or symptoms of pulpal pathology no pathology visible on radiographs tooth exfoliated	restoration appears satisfactory, no intervention required no clinical signs or symptoms of pulpal pathology no pathology visible on radiographs tooth exfoliated
'Minor' failure	secondary caries, or new caries clinically or radiographically restoration fracture or wear requiring intervention restoration loss; tooth restorable reversible pulpitis treated without requiring pulpotomy or extraction	crown perforation new caries (around margins) restoration loss; tooth restorable reversible pulpitis treated without requiring pulpotomy or extraction
'Major' failure	irreversible pulpitis or dental abscess requiring pulpotomy or extraction inter-radicular radiolucency restoration loss; tooth unrestorable internal root resorption	irreversible pulpitis or dental abscess requiring pulpotomy or extraction inter-radicular radiolucency restoration loss; tooth unrestorable internal root resorption
