The stainless steel crown (SSC) is an extremely durable restoration with several clear-cut indications for use in primary teeth including: following a pulpotomy/pulpectomy; for teeth with developmental defects or large carious lesions involving multiple surfaces where an amalgam is likely to fail; and for fractured teeth. In other situations, its use is less clear cut, and caries risk factors, restoration longevity and cost effectiveness are considerations in decisions to use the SSC. The literature on caries risk factors in young children indicates that children at high risk exhibiting anterior tooth decay and/or molar caries may benefit by treatment with stainless steel crowns to protect the remaining at-risk tooth surfaces. Studies evaluating restoration longevity, including the durability and lifespan of SSCs and Class II amalgams demonstrate the superiority of SSCs for both parameters. Children with extensive decay, large lesions or multiple surface lesions in primary molars should be treated with stainless steel crowns. Because of the protection from future decay provided by their feature of full coverage and their increased durability and longevity, strong consideration should be given to the use of SSCs in children who require general anesthesia. Finally, a strong argument for the use of the SSC restoration is its cost effectiveness based on its durability and longevity.
不锈钢冠（SSC）是一种极其耐用的修复体，在乳牙中有几个明确的使用指征，包括：在进行牙髓切断术/牙髓摘除术后；用于有发育缺陷或涉及多个面的大龋损的牙齿，在这种情况下银汞合金修复可能会失败；以及用于折裂牙。在其他情况下，其使用并不那么明确，在决定是否使用SSC时，需要考虑患龋风险因素、修复体的使用寿命和成本效益。关于幼儿患龋风险因素的文献表明，有患上前牙龋和/或磨牙龋高风险的儿童，使用不锈钢冠进行治疗可能有助于保护其余有风险的牙面。评估修复体使用寿命的研究，包括SSC和II类银汞合金的耐久性和寿命，均表明SSC在这两个参数方面具有优越性。乳牙有广泛龋坏、大的龋损或多个面龋损的儿童，应使用不锈钢冠进行治疗。由于其全覆盖的特点能防止未来龋坏，且耐久性和使用寿命增加，对于需要全身麻醉的儿童，应充分考虑使用SSC。最后，基于其耐久性和寿命，SSC修复体具有成本效益，这是支持使用它的有力论据。
