Cochrane Oral Health's Trials Register

Cochrane Oral Health's Trials Register contains reports of controlled clinical trials (CCTs), randomised controlled trials (RCTs) and systematic reviews (SRs) related to the scope of the Group and which may be of interest to review authors undertaking Cochrane systematic reviews. It is managed and maintained by Cochrane Oral Health's Information Specialist, at the Editorial Base. The Register forms part of the Cochrane Register of Studies

In addition to references to full papers it also includes materials such as published correspondence, conference proceedings, research abstracts, etc.

Monthly searches of the Cochrane Central Register of Controlled Trials (CENTRALare undertaken to populate the Register with CCTs and RCTs. MEDLINE and Embase are searched to identify relevant systematic reviews.

The full scope searches are available to download in PDF format.

Search results are initially screened using the Classifier, a machine-learning tool within the Cochrane Register of Studies, which uses classifications from Cochrane Crowd to identify controlled trials and the existing register records to identify records which are in the Group's scope. Any records which are more than 8% likely to be within scope are screened by Cochrane Oral Health's information specialist, along with any records that are more than 10% likely to be a systematic review. The records are then coded as RCTs, CCTs or SRs, and any that are eligible for publication in Cochrane's Central Register of Controlled Trials (CENTRAL) are submitted to Cochrane's publisher, Wiley.

Additional trials found by authors of Cochrane Oral Health reviews during the review process are added to the Register as reviews are published or updated.

Handsearching has been undertaken by a team of volunteers over the years. Any randomised controlled trials identified by handsearching have been added to Cochrane Oral Heath's Trials Register, and published in the CENTRAL database. A full list of journals that have been handsearched can be found here. Abstracts from the various meetings of the International Association of Dental Research (IADR) are added on an annual basis.

Containing more than 50,000 records, the Register provides a valuable starting point for Cochrane review authors searching for controlled clinical trials (RCTs/CCTs) on oral health topics. Searches of the Register are conducted at the Editorial Base by Cochrane Oral Health's Information Specialist, and are currently only undertaken for Cochrane review authors.
