Abstract: restoring severely decayed primary teeth due to their strength, durability, cost-effectiveness, and long-term clinical success.5 For over five decades, SSCs have been valued for providing full coronal coverage, particularly in primary molars with extensive carious lesions.Recent advancements have improved their anatomical accuracy, allowing for better replication of natural IntroductIonThe deciduous dentition is a fundamental component in the craniofacial, neuromuscular, and psychosocial development of the pediatric population, maintaining structural and functional continuity until the eruption of the permanent dentition.Early loss of primary teeth can adversely affect key physiological functions such as mastication, phonation, and occlusal development.Additionally, premature exfoliation secondary to carious lesions is frequently implicated in the etiology of space loss and developing malocclusions, often necessitating interceptive or corrective orthodontic therapy in the mixed or permanent dentition stages.1,2 The clinical management of carious lesions in primary teeth is multifactorial and becomes increasingly complex in cases involving extensive cavitation or in patients with a high caries risk profile.3 Therapeutic strategies should aim to reestablish functional occlusion and esthetic harmony while simultaneously reinforcing the compromised coronal structure.Current evidence-based pediatric restorative approaches utilize a range of biomimetic and bioactive materials, including dental amalgam, glass ionomer cement (GIC), light-activated resin composites, and full-coronal restorations such as preformed pediatric crowns.4 Stainless steel crowns (SSCs), also known as chrome steel or prefabricated metal crowns, are a widely preferred option for 1,3-
