Zirconia crowns have become a popular esthetic restorative option; however, limited evidence is available regarding the clinical performance of custom-made zirconia crowns compared with prefabricated zirconia crowns. This randomized controlled clinical trial aims to compare the clinical performance of custom-made and prefabricated zirconia crowns placed on pulpotomized primary molars. Clinical performance will be evaluated using standardized clinical and radiographic outcome measures over the follow-up period to determine whether custom-made zirconia crowns provide comparable or improved outcomes.",[52,53],"Primary Molar Tooth","Pulpotomies Primary Teeth",[55,56],"Zirconia Crown","Customer","NOT_YET_RECRUITING","2026-07-29",{"date":60,"type":61},"2026-07-31","ACTUAL",{"date":63,"type":46},"2026-11",{"date":65,"type":46},"2027-11",{"name":5,"class":6}]
