About this Research Topic

Background

Popularly termed "chalky teeth", molar hypomineralisation (MH) is an under-recognised medico-dental problem that puts one-in-five children worldwide at elevated risk for tooth decay, dental pain and appearance-related psychosocial harm. These liabilities reduce quality of life for affected individuals and also impose large costs on society, both socially and economically. If the global health burden of MH is to be alleviated, we need to take a lifecourse approach to better understand (1) the underlying disruptions during tooth development inside the jaw (i.e. developmental pathophysiology) with a view to medical prevention, and (2) the clinical and public health issues, focussing on chalky 2-year, 6-year and 12-year molars – the teeth at highest risk of accelerated decay. Progress towards such goals has thus far been obstructed by poor awareness of MH – at scientific, healthcare professional, political and public levels and consequent lack of research momentum. Since 2010, 'The D3 Group for developmental dental defects' (D3G; https://www.thed3group.org) has taken a translational approach to:

1. Develop a stronger definition for MH that emphasises scientific hallmarks and eliminates widespread confusion around incisors. This definition has recently been adopted by USA's National Library of Medicine;
2. Introduce an underpinning classification for MH and other demarcated opacity disorders (“DODs");
3. Adopt a lifecourse approach recognising that MH involves both primary and permanent teeth;
4. Craft translational terminology to enable clear communication between all stakeholders.

In 2020, and in collaboration with The University of Toronto and SickKids Hospital, D3G launched a series of international events (webinars, taskforce meetings, live symposium) recognising 100 years of chalky teeth research. A D3G research team also published breakthrough findings about MH pathophysiology.

To chronicle these ground-breaking advances in D3-science translation, this far-reaching article collection provides a cutting-edge platform for sharing the collective perspectives, ideas, and research concepts from these events (now called the 'Toronto D3 Framework') across basic, applied and end-translational domains. We invite participant teams to draw academic attention to the 'MH-Chalky Teeth Problem' by illustrating its worldwide burdens and the need for a holistic response from all stakeholders – researchers, dental and other healthcare providers, educators, industry, government, and the at-risk public.

Subtopics of interest include but are not limited to:
• Perspectives on the MH-Chalky Teeth problem from various stakeholder groups and geographic regions
• Research in underpinning basic science as well aetiological, clinical and public health arenas
• Historical reappraisals aiming to build a stronger clinico-scientific foundation for future research
• Initiatives aimed at strengthening scientific underpinnings including terminology, definitions and classification

Authors are encouraged to exploit the diverse range of publication types available through the four participating Frontiers journals and are encouraged to adopt D3G's standardized translational terminology (MH, chalky 2-year molars etc), as implemented at the Toronto D3 events and now increasingly across the sector [https://www.thed3group.org/molar-hypomin-terminology.html]. A more detailed guideline for writers and reviewers is available (see Frontiers Writers guidelines: https://www.thed3group.org/writer-reviewer-guide.html).

To ensure suitability for inclusion in this unique article collection, the Guest Editors would like to encourage all interested individuals to submit a summary of their manuscript before preparing a full manuscript.

Guest Editor Prof. Mike Hubbard is Founder/Director of The D3 Group, an international network/charity he runs based at the University of Melbourne, Australia.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
