Summer 2018

Welcome to the latest issue of our newsletter! We've been busy spreading the word about Cochrane reviews in the last few months, with our editorial team taking trips to Croatia and China. We've also been looking at ways to treat the dental pulp in primary teeth, and the best methods for making complete and partial dentures. Keep in touch with us between newsletters by signing up to our blog, following us on Twitter or liking us on Facebook.

Cochrane Oral Health in Zagreb

In April 2018, Cochrane Oral Health Co-ordinating Editors Jan Clarkson and Helen Worthington travelled to Zagreb in Croatia to talk about methodological characteristics of Cochrane systematic reviews at Cochrane Croatia's training event. The theme was "Evidence-based dental medicine" and Helen and Jan were joined by Croatian experts in dental medicine as part of Cochrane Croatia's educational programme.

Jan is pictured here with Tina Poklepovic Pericic, Cochrane Oral Health author and director at Cochrane Croatia.

8th International Conference on Methodological Issues in Oral Health Research, Hong Kong

In May, Co-ordinating Editor Professor Helen Worthington, and our editors Professor Tanya Walsh and Professor Ian Needleman travelled to Hong Kong to speak at the 8th International Conference on Methodological Issues in Oral Health Research. They joined our statistical editor Professor May Wong, who was one of the chief organisers of the conference. Cochrane Oral Health was well represented by the editorial team. Professor Wong spoke about statistical methods in meta-analysis; and Professor Needleman gave a presentation on the quality of systematic reviews. Professor Worthington's keynote address was on the editor's perspective on evidence-based dentistry and systematic reviews, and Professor Walsh spoke at the pre-conference event on conducting systematic reviews and network meta-analysis.

Another of our editors, Professor Analia Veitz-Keenan, spoke at the symposium on evidence-based dentistry in the dental curriculum.

Following the conference, Professor Worthington and Professor Walsh - with Co-ordinating Editor Professor Jan Clarkson and our editor Professor Paul Coulthard - travelled to Wuhan University in China, for a tour of the university's new Evidence-Based Dentistry Centre, and a meeting with our Wuhan-based editor Dr. Fang Hua.

New Cochrane networks established

Cochrane has recently undergone a restructure, and all Cochrane review groups have been organized into networks. Cochrane Oral Health is now part of the Cochrane Long-term Conditions and Ageing 2 Network, with our colleagues from Cochrane Skin, Cochrane Wounds, Cochrane Back and Neck, Cochrane Eyes and Vision, Cochrane Musculoskeletal, Cochrane Ear, Nose and Throat and Cochrane Pain, Palliative and Supportive Care.

The aim of the networks is to co-ordinate the work of groups working across similar topics. The Long-term Conditions and Ageing 2 Network is led by Senior Editor Peter Tugwell. Peter is an author on several Cochrane Oral Health reviews, including our reviews on flossing and interdental brushing. He is supported in his new role by Associate Editor Nuala Livingstone.

Find out more about Long-term Conditions and Ageing 2 by visiting the network website. You can read more about the networks at the CRG Networks' Portal.

Cochrane Database of Systematic Reviews impact factor increase

The 2017 Journal Citation Report (JCR) has been released by Clarivate Analytics, and the new impact factor for the Cochrane Database of Systematic Reviews (CDSR) is 6.754. This represents a significant increase on the previous impact factor of 6.264.

This means that the CDSR is now ranked 12th of the 154 journals in the Medicine, General and Internal category. Read more.

Preview the new Cochrane Library

The Cochrane Library holds all Cochrane Oral Health systematic reviews and protocols, and it is currently undergoing a revamp, with new functionality and content. In the new version, subscribers can access Cochrane Clinical Answers, which aims to provide readable, digestible, clinically-focused entry point to rigorous research from Cochrane Reviews. Subscribers can also browse Oral Health reviews, protocols and trials, and will have access to Cochrane Library editorials and special collections.

Preview the new Cochrane Library site here. Find out more information on access to the Cochrane Library here.

Selected highlights of the Cochrane Library are also available via an app. All content in the app is completely free. See more information on how to download the app, here.

Core outcomes set for dental caries - take part in an eDelphi

A team of researchers from the University of Dundee are conducting a consensus study to identify core outcomes when assessing the effects of prevention and treatment interventions for managing carious lesions. The consensus study contributes to the international Core Outcome Measures in Effectiveness Trials initiative, which attempts to bring together patients, clinicians and researchers to identify which outcomes are most important and relevant to measure, in order to assist informed healthcare decision-making and improve future research.

If you are an author on a Cochrane review with an interest in caries, the team in Dundee would love to hear from you. Find out more here.

New Cochrane-wide peer review policy

On Monday 16th April Cochrane published the first Cochrane-wide peer review policy. In addition to standardising current practice across all of Cochrane’s 53 Review Groups, the introduction of the new policy aims to improve transparency in communication and decision making, consistent with core Cochrane principles, and taking the opportunity to implement current best practice.

The key highlights of the new policy include:
  • From January 2019 Cochrane will adopt a named peer review policy, whereby authors and peer reviewers know each other’s identities during the peer review process.
  • A decision workflow for deciding when to peer review updated protocols and updated Cochrane Reviews.
  • A minimum number and type of peer reviewer.
  • A minimum standard for acknowledgement of peer reviewer contributions.
