The objective of this clinical trial was to evaluate and compare two full-coronal restoration [stainless steel crowns (SSCs) and zirconia crown] in carious primary posterior teeth.
Forty endodontically treated primary teeth in children within the age-group of 3-9 years were selected and divided into two equal groups (20 SSCs and 20 zirconia crown). The two crowns were evaluated for retentivity of crown, temporomandibular joint (TMJ) problem, gingival response, plaque accumulation, and tooth wear in opposing teeth after 1 and 3 month follow-up.
Both the crowns showed 100% results regarding TMJ problems, but SSCs performed better in terms of retention of crown, gingival response, plaque accumulation, and tooth wear in opposing teeth. The statistics showed significant result by using Mann-Whitney test and Wilcoxon signed-rank test.
Stainless steel crowns performed better among both the full-coronal restoration for posterior primary teeth.
Stainless steel crowns remain "Gold Standard", for posterior full coverage restorations in primary molars as compared to zirconia crowns.

本临床试验的目的是评估和比较两种全冠修复体[不锈钢冠（SSC）和氧化锆冠]用于龋坏的乳后牙。
选取3至9岁儿童的40颗经牙髓治疗的乳牙，分为两组，每组20颗（20颗不锈钢冠和20颗氧化锆冠）。在随访1个月和3个月后，评估两种冠的固位力、颞下颌关节（TMJ）问题、牙龈反应、菌斑积聚以及对颌牙的磨损情况。
两种冠在TMJ问题方面的结果均为100%，但不锈钢冠在冠的固位力、牙龈反应、菌斑积聚以及对颌牙磨损方面表现更好。使用曼-惠特尼检验和威尔科克森符号秩检验，统计结果显示差异有统计学意义。
在两种用于乳后牙的全冠修复体中，不锈钢冠表现更佳。
与氧化锆冠相比，不锈钢冠仍是乳磨牙全冠修复的“金标准”。
