Priority reviews

Cochrane Oral Health has undertaken an extensive prioritisation process, to determine the priority areas for evidence synthesis in oral health. Find out how we went about prioritising our reviews here.

The following titles are our priority reviews for updating or undertaking during the period 2021 to 2024. 

Priority reviews to update

The following titles are reviews previously published by Cochrane Oral Health. They have been prioritised for updating, and are presented in rank order, as decided by our panel of consumers, policy-makers, guideline developers, clinicians and researchers. The decisions on each topic were made by the Cochrane Oral Health Editorial Base team:

Priority topics for new reviews

A number of topic areas emerged from the priority setting process which currently do not form part of Cochrane Oral Health's portfolio. We may register, undertake, and publish a selection of new reviews in the period 2021 to 2024. Some priority topics are too broad in scope for a single systematic review, and some overlap reviews we already have registered. Our decisions on each priority topic are outlined in the table below, the decisions on each topic were made by the Cochrane Oral Health Editorial Base team. They are presented in rank order, as decided by our panel of consumers, policy-makers, guideline developers, clinicians and researchers:

Review title

Decision

What are the best ways to prevent tooth decay and oral disease in the elderly?

This is a broad question, and we believe that we have already covered many aspects of this topic. We will develop a special collection for Cochrane Oral Health’s website, highlighting the reviews that cover this question, with an accompanying commentary. This will be a pilot project and will be completed in 2021.

How can oral cancer be prevented?

This is a broad question, and we believe that we and other Cochrane review groups have already covered many aspects of this topic. If our pilot project to develop a special collection for on prevention of oral disease in the elderly is a success, we will develop a special collection for Cochrane Oral Health’s website on this topic, highlighting the reviews that cover this question.

What is the best way to promote better oral health?

This is a broad question, and we believe that we and other Cochrane review groups have already covered many aspects of this topic. If our pilot project to develop a special collection for on prevention of oral disease in the elderly is a success, we will develop a special collection for Cochrane Oral Health’s website on this topic, highlighting the reviews that cover this question.

What is the best way to measure the risk of tooth decay?

After discussion, we decided that this question is not suitable for a Cochrane review, although it is an important question. It would also overlap work currently being undertaken by the Scottish Dental Clinical Effectiveness Programme, and we do not want to contribute to research waste.

At what stage of tooth decay should a dentist use a drill?

This is a broad question, and we believe that we have already covered many aspects of this topic. If our pilot project to develop a special collection for on prevention of oral disease in the elderly is a success, we will develop a special collection for Cochrane Oral Health’s website on this topic, highlighting the reviews that cover this question.

How should I brush my teeth? For how long, and how often?

We agreed that there was not enough available evidence to warrant separate reviews on these questions. Instead, we will incorporate what little evidence there is in our existing reviews on toothbrushing and toothpaste.

What are the best ways to prevent oral diseases in the elderly living in nursing homes or other institutions?

After our pilot project, creating a special collection on prevention of oral disease in the elderly is complete in 2021, we will see if we have gaps in our review portfolio which could be filled by a new review on one or more aspects of this question.

By changing parental, or primary care-giver behaviours, can tooth decay in children be prevented?

There is potential for a new title to be registered. We will seek help from experts in the field to scope out a new title.

Interventions for managing root caries

This title has already been registered and a review is underway. We aim to publish before 2023.

Does a better diet or diet supplements improve oral health? If so what are the best foods/nutrients/supplements?

This is a broad question and there is potential for one or more new titles to be registered. We will advertise this as a priority vacant topic area on our website and in our newsletter.

What role does technology play in providing dental care?

This is a very broad topic area and there is potential for one or more new titles to be registered. We agreed that we would like to explore the area of teledentistry in the light of the COVID-19 pandemic. We will look to see if there is funding available to progress a review in this area.

Topical silver diamine fluoride for managing dental caries in children and adults

This title has already been registered and a review is underway. We aim to publish before 2023.

Psychological interventions for improving adherence to oral hygiene instructions in adults with periodontal diseases

This title has already been registered and a review is underway. We aim to publish before 2023.

Adjunctive systemic antimicrobials for the non-surgical treatment of chronic and aggressive periodontitis

This title has already been registered and a review is underway. We aim to publish before 2023.

Can taking probiotics (live bacteria and yeasts) prevent and control chronic gum disease (periodontitis)?

We will convene a meeting to get advice from clinical experts in the field of periodontitis, to understand how we might approach this review and make it clinically relevant. There is potential for a new Cochrane review.
