To identify controlled clinical trials (CCTs) published in Spanish and in Latin American dental journals, and provide access to this body of evidence in a single source.
Handsearching, following Cochrane Collaboration guidelines, of CCTs published in Spanish dental journals from Spain and Latin America. For each eligible trial, we collected the dental specialty, the interventions evaluated, whether and how randomisation was achieved, and the corresponding bibliographic reference.
We handsearched 107 journals published in Spain and Latin America in Spanish. Over 17 051 articles, 244 (1.43%) were CCTs. These studies focused mainly on periodontics (70, 29.0%) and oral and maxillofacial surgery (66, 27.0%), assessing mostly pharmacological interventions (112, 46.0%). One hundred fifty-three studies (62.7%) used a random allocation of participants to study arms.
A significant number of dental journals published in Spain and Latin America in Spanish language present original research relevant to inform clinical practice. These journals are not indexed in the major electronic databases.
References to the identified CCTs are now available in CENTRAL, the Cochrane Collaboration repository for these studies. We call for adherence to the CONSORT statement in dentistry to improve reporting of CCTs in journals published in Spanish language.
为了识别发表在西班牙语和拉丁美洲牙科学术期刊中的对照临床试验（CCT），并在单一来源中提供获取这些证据的途径。
根据 Cochrane 协作组的指南，对西班牙和拉丁美洲西班牙语牙科学术期刊中的 CCT 进行手工检索。对于每个合格的试验，我们收集了牙科专业、评估的干预措施、是否以及如何实现随机化，以及相应的文献参考。
我们对西班牙和拉丁美洲以西班牙语出版的 107 种期刊进行了手工检索。在超过 17051 篇文章中，有 244 篇（1.43%）为 CCT。这些研究主要集中在牙周病学（70 篇，29.0%）和口腔颌面外科（66 篇，27.0%），评估的大多是药理学干预（112 篇，46.0%）。153 项研究（62.7%）使用随机分配参与者到研究组。
大量以西班牙语出版的西班牙和拉丁美洲牙科学术期刊发表了与临床实践相关的原始研究。这些期刊未被主要电子数据库索引。
现已在 CENTRAL（Cochrane 协作组针对这些研究的存储库）中提供了确定的 CCT 的参考文献。我们呼吁在牙科学术期刊中遵守 CONSORT 声明，以提高 CCT 的报告质量。
