Early childhood caries is a common chronic disease affecting children and often requires extensive restorative treatments. Stainless steel crowns (SSC) and preformed zirconia crowns (PZC) are two of the most widely used options in pediatric dentistry. SSC, introduced in 1950, are known for their durability, ease of placement, and low cost, although they have limited aesthetics due to their metallic appearance. In contrast, PZC offer an attractive aesthetic alternative, mimicking the natural tooth color, catering to the growing demand from parents for more aesthetic restorations. In terms of gingival health and plaque accumulation, PZC exhibit lower bacterial plaque adhesion and reduced gingival inflammation compared to SSC, due to their highly polished surface. Nevertheless, both options offer successful clinical outcomes in terms of longevity. Regarding retention, SSC excel in long-term stability and resistance, though PZC also demonstrate high retention rates, particularly during the first years of follow-up. However, PZC require greater tooth reduction for placement, which may compromise pulpal health and increase operative time. A critical aspect is the wear on opposing teeth, as PZC may cause slight wear, whereas SSC show less abrasion, making them more suitable for restorations in posterior sectors. Additionally, preparation time for PZC is longer since they do not allow adjustments after fabrication, unlike SSC. In conclusion, both crowns have advantages and disadvantages. The selection depends on clinical factors and the preferences of patients and their parents. SSC provide a durable and economical option, while PZC stand out for their aesthetics and gingival health benefits, albeit with higher costs and longer operative times.
