Correct answer: A — Significantly higher longevity and lower failure rates

Stainless-steel crowns have significantly higher longevity and lower failure rates compared to multi-surface (Class II) amalgam or composite restorations in primary molars. Studies show SSC failure rates of <5% versus 15-40% for multi-surface intracoronal restorations over the life of the primary tooth. SSCs provide complete cuspal coverage, preventing fracture, and restore anatomy and function predictably. The Hall technique (cemented without preparation) has further simplified placement.
