The aim of this retrospective study was to evaluate the outcome of preformed metallic crowns (PMC) utilizing the HT in carious primary molars for children treated within public dental clinics across the Sydney region.
A retrospective cohort study was designed, whereby two investigators evaluated 113 primary molars treated with HT PMCs involving 71 participants (aged between 5 and 11 years) after a minimum of 6 months post treatment. The mean time elapsed between crown placement (treatment) and the review was 1.42 years (17 months). The outcome of the HT was assessed by clinical and radiographic criteria.
One hundred thirteen HT PMCs were reviewed from 71 participants. The overall success rate of PMCs placed utilizing the HT was 99%, with only one case presenting with confirmed failure.
HT PMCs have an overall high success rate as a treatment option in carious primary molars.
本回顾性研究的目的是评估在悉尼地区公立牙科诊所接受治疗的儿童中，利用 HT 在前龋的恒牙上制作预成金属冠（PMC）的治疗效果。
设计了一项回顾性队列研究，由两名研究者对 71 名 5 至 11 岁儿童的 113 颗恒磨牙进行了评估，这些儿童在接受 HT PMC 治疗后至少随访了 6 个月。从牙冠放置（治疗）到复查的平均时间间隔为 1.42 年（17 个月）。通过临床和放射学标准评估 HT 的结果。
从 71 名患者中回顾了 113 颗 HT PMC。利用 HT 制作的 PMC 的总体成功率为 99%，仅 1 例出现确诊失败。
HT PMC 作为治疗龋齿恒磨牙的一种选择，具有较高的总体成功率。
