The benefits of restorative treatment are to remove cavities or defects, to restore function, maintain the arch integrity and to eliminate the progression of dental caries. The complexity of restorative treatment increases when the dental caries involves more than one surface of the tooth. Stainless steel crowns are considered to be the gold standard for multisurface carious lesions in primary teeth. Despite the high success rate and cost-effectiveness of stainless steel crowns compared to other restorations, failure of stainless steel crowns were reported in some cases. The major causes of failure of stainless steel crowns are poor marginal adaptation and marginal discrepancy.
