The overall pooled success rate of the Hall Technique (HT) in various types of studies has not been investigated. The present study aims to evaluate the success rate of HT to restore carious primary molars.
A systematic search was carried out in the MEDLINE/PubMed, Excerpta Medica Database (EMBASE), Scopus, Web of Science, and LIVIVO electronic databases, as well as the ProQuest database for grey literature review. A search was carried out up to September 2023 for studies meeting the eligibility criteria: Randomised Clinical Trials (RCTs) and Non-Randomised Studies of Interventions (NRSIs); children with primary molars treated using HT; and reporting success for at least 1-month post-treatment. Single-arm meta-analysis assessed the pooled proportion (95% CI) of HT success rates. Risk of bias and certainty of evidence using the GRADE approach were assessed.
Searching identified 665 studies, with 25 (15 RCTs and 10 NRSIs) meeting the eligibility criteria. In meta-analyses of RCTs, the pooled proportion success rate was 98% (95% CI: 97-99%) at 12-month follow-up. For NRSIs, the pooled proportion success rate was 95% (95% CI: 91-100%) up to 89 months.
HT presents a high success rate, even though the primary studies had "low" to "high" risk of bias and demonstrated "moderate" to "low" certainty of evidence. One of the main reasons for downgrading was related to blinding, which was generally unfeasible due to visibly different restorative materials. The systematic review protocol was registered in PROSPERO (ID: CRD42021204415).
尚未对霍尔技术（HT）在各类研究中的总体合并成功率进行调查。本研究旨在评估HT修复龋损乳牙的成功率。
在MEDLINE/PubMed、医学文摘数据库（EMBASE）、Scopus、科学网和LIVIVO电子数据库以及ProQuest数据库中进行系统检索，以进行灰色文献综述。检索截至2023年9月，查找符合纳入标准的研究：随机临床试验（RCT）和非随机干预研究（NRSI）；使用HT治疗乳牙的儿童；以及报告治疗后至少1个月成功情况的研究。单臂荟萃分析评估了HT成功率的合并比例（95%置信区间）。使用GRADE方法评估偏倚风险和证据确定性。
检索到665项研究，其中25项（15项RCT和10项NRSI）符合纳入标准。在RCT的荟萃分析中，12个月随访时合并成功率为98%（95%置信区间：97 - 99%）。对于NRSI，长达89个月时合并成功率为95%（95%置信区间：91 - 100%）。
尽管原始研究存在“低”至“高”的偏倚风险且证据确定性为“中等”至“低”，但HT仍呈现出较高的成功率。证据降级的主要原因之一与盲法有关，由于修复材料明显不同，盲法通常不可行。系统评价方案已在PROSPERO中注册（标识符：CRD42021204415）。
