Retentive strength data are critical to predicting the long-term clinical performance of zirconia crowns for primary teeth. : This research assessed the clinical outcome of prefabricated zirconia crowns (PZCs) cemented with either self-adhesive resin cement or pure glass ionomer cement in the primary teeth of children. : In the present research, a sample of 162 prefabricated zirconia crowns were collected through convenience sampling. A follow-up examination was conducted at 12 and 24 months to assess the clinical outcomes of PZCs post cementation. : Zirconia crowns cemented with self-adhesive resin showed high clinical outcomes at both 12 and 24 months, with 95.1% of crowns retained. In contrast, crowns cemented with glass ionomer cement had slightly lower clinical outcomes, with 91.4% retained at 12 months and 84.0% retained at 24 months, indicating a significant difference (-value). Long-term follow-up is crucial for the optimal maintenance of crown stability. : Self-adhesive resin cement is a viable option for cementing PZCs in pediatric dentistry, demonstrating satisfactory clinical performance over both 12 and 24 months. Future studies comparing different types of cement are recommended for further validation of these results.
固位强度数据对于预测乳牙氧化锆冠的长期临床性能至关重要。本研究评估了用自粘树脂水门汀或纯玻璃离子水门汀粘结的预成氧化锆冠（PZCs）在儿童乳牙中的临床效果。在本研究中，通过便利抽样收集了162个预成氧化锆冠样本。在12个月和24个月时进行随访检查，以评估粘结后PZCs的临床效果。用自粘树脂粘结的氧化锆冠在12个月和24个月时均显示出较高的临床效果，95.1%的冠得以保留。相比之下，用玻璃离子水门汀粘结的冠临床效果略低，12个月时保留率为91.4%，24个月时保留率为84.0%，表明存在显著差异（P值）。长期随访对于冠稳定性的最佳维持至关重要。自粘树脂水门汀是儿科牙科中粘结PZCs的可行选择，在12个月和24个月时均表现出令人满意的临床性能。建议未来进行比较不同类型水门汀的研究，以进一步验证这些结果。
