The secondary outcomes included assessment of the marginal fit and adaptation of preformed crowns using both techniques, analysis of changes in occlusal relationships-specifically the vertical dimension of occlusion and overbite-and evaluation of patient satisfaction. Patient satisfaction was measured using a five-point Likert scale at multiple time points: immediately post-treatment, and at one, three, and six months.",[87,88,89,90],"Permanent Molars","Dental Caries","Tooth Decay","Permanent First Molar Caries",[9,92,93,88],"Stainless Steel Crowns","Permanent First Molars","NOT_YET_RECRUITING","2025-11-23",{"date":97,"type":98},"2025-11-28","ACTUAL",{"date":100,"type":81},"2025-11",{"date":102,"type":81},"2026-05",{"name":5,"class":6},1]
