Conventional and Hall Technique (HT) Preformed Metal Crowns (PMCs) are used for treatment of carious primary molars. The aim was to evaluate the clinical and radiographic success of conventional and HT PMCs in a postgraduate dental setting.
A retrospective study using patients' electronic case-notes and radiographic images of carious primary molars treated with either conventional or HT PMCs was conducted to assess clinical and radiographic success/failure. A Kaplan-Meier curve was used to assess PMC survival.
187 PMCs (110 HT and 77 conventional) in 65 children (34 females and 31 males) at 6, 12, 18 and 24 months were assessed. At 24 months, the success rates of conventional and HT PMCs were 97.6% and 93.5%, respectively. Two HT (perforated/abscessed) and four conventional (abscessed) PMCs failures occurred. There was no significant difference in success/failure (p = 0.362) at 12 months, but the HT was more successful at 24 months (p = 0.002) with similar survival times for both methods.
HT and conventionally placed PMCs, when placed in a postgraduate paediatric dentistry setting, were clinically and radiographically very successful at 6, 12, 18 and 24 months post operatively with a slightly higher success of the HT at 24 months.
传统技术和 Hall 技术（HT）预成金属冠（PMC）用于治疗龋坏的乳磨牙。本研究旨在评估在研究生口腔环境下，传统和 HT PMC 的临床和放射学成功率。
本研究采用回顾性病例研究，通过电子病历和龋坏乳磨牙接受传统或 HT PMC 治疗的放射图像，评估临床和放射学成功/失败情况。Kaplan-Meier 曲线用于评估 PMC 存活率。
在 6、12、18 和 24 个月时，对 65 名儿童（34 名女性和 31 名男性）的 187 个 PMC（110 个 HT 和 77 个传统）进行了评估。在 24 个月时，传统和 HT PMC 的成功率分别为 97.6%和 93.5%。发生了 2 例 HT（穿孔/脓肿）和 4 例传统 PMC（脓肿）失败。在 12 个月时，两种方法的成功率没有显著差异（p=0.362），但在 24 个月时，HT 更为成功（p=0.002），两种方法的存活时间相似。
在研究生口腔儿科环境中，当 HT 和传统方法放置 PMC 时，在术后 6、12、18 和 24 个月时，临床和放射学上都非常成功，HT 在 24 个月时的成功率略高。
