Our Group and our Mission

The D3 group

Formally The D3 Group (D3G) comprises a translational research and education network spanning the Developmental Dental Defect (DDD = D3) sector, originally in Australia and New Zealand (the Hub) and increasingly around the world. But actually we are an eclectic bunch of individuals whose lives have been touched by D3 problems one way or another. Some of our families have experienced D3s first hand, many of us care for people with D3s either as dental practitioners or public health professionals, and many others are engaged in D3 research and education. We are also pleased to have a growing number of medicos and D3-savvy folk from industry amongst us (see D3G Down Under and International Friends).

All of us share the vision that teaming up and pulling together in a global "D3 family" effort will help get "chalky teeth" problems such as Molar Hypomin, AI and allied tooth decay recognised better, understood better, and cared for better. Our overall mission is to make many of these problems go away through prevention – at medical (primary), dental (secondary) and social levels.

To achieve these social benefits, our primary aim is to help educate people about D3s as they pertain them – families and patients, the public health sector and politicians, practitioners and industry, researchers, educators and students. Hopefully, such an improved foundation of science-based knowledge and understanding will lead to widespread benefits across societies.

Besides our focus on education and advocacy, we also aim to foster improved research and healthcare of D3s. To do so, a key goal is to develop and exploit a scientifically-driven translational research network that strengthens our field and connects it with others – across Australasia and around the world. In other words, our action plan is to develop a pathway "towards stronger science and social good".

More specifically, our key objectives are to:

  • hold scientific/network meetings and workshops of interest to our diverse membership
  • disseminate information – to D3G members, students and the public
  • undertake strategic planning and development – strengthening global efforts toward D3
  • foster research and training – build teams, support researchers and trainees
  • improve the health and well-being of people afflicted with D3s or chalky teeth

The D3 Movement

Increasingly we hear others talk about "the D3 movement" which of course is very pleasing to us – optimistically presuming this apparent compliment reflects awareness of what we're up to and where we're headed. We first used this expression in 2013 when launching the D3G website and Chalky Teeth Campaign (see report from here), little realising that those early dreams – to bring science, medicine and dentistry together to do something special for kids and society – would turn into today's reality.

So in preparation for our 2021 D3 Research Incubator, it's timely to provide a one-liner update on how we see the D3 movement today, as follows.

The D3 movement is an international, science-driven, paediatric health initiative
aimed at improving societies worldwide

To justify this statement, we proudly point to wins from the Chalky Teeth Campaign (WFCT network, HB=ST, Sam's Story Club), international engagement and social impact.

Our Culture and Our Values

The D3 group

In 2020, respecting Australia's national week of indigenous reconciliation events (learn more), we drafted the following acknowledgement alongside contextual information shaped as a forward-looking culture/values statement for D3G. And then in 2021, we introduced an annual quote taken from an article we found particularly helpful in our own learning, and added the section about traversing From Acknowledgement to Action.

Our intent is not only to support the ongoing need for reconciliation but also to set the scene for D3G's collaborative future-building by expressing thoughts on overlapping issues, past and present. While focussed on Australasia, we'd like our international membership to help refine these thoughts into a translationally robust statement that has
global meaningfulness – so comments are welcomed (contact us).

2021 quote: "Indigenous people talk of, and to, Country, as they would another person." (taken from here).

D3G's cultural acknowledgement

D3G acknowledges Country, the mistakes of colonialism, and the residual gaps – plus the broader needs to respect history, culture, diversity and science – as we all collaborate to build a better future for humankind.

D3G's worldview and values – our 'D3 family creed'

  • Per the hit song by "Men at Work", D3G "comes from the land down under" (D3G Down Under) where life today is exceptionally good for many – this obviously puts us in a privileged position to build a global network and pursue our scientifically-driven social mission.
  • Accordingly, we undertake to work in a responsible manner befitting our modern societies – being humanist-rules-based and multicultural – and to foster our vision of helping all humankind through advancement of D3 science, education and healthcare.
  • In so doing, we acknowledge that, as is typical of colonialism, the histories of many countries are marred by poor behaviour toward the indigenous peoples – who not only were forced to share their land ("country") but also had their cultural specialities and assimilation needs neglected, leading to inequities ("gaps") that persist today. Hence, we will try to help "close the gaps" and foster equalities through the work we do.
  • We also gratefully salute the many people, from down under and around the world, who fought for the freedom and sociocultural beliefs we leverage today.
  • Last and not least, we respect the (well-evidenced) social good of science and allied reasoning, and praise our predecessors across the healthcare sector on whose shoulders we stand.

From acknowledgement to action

Pay It Forward

As for the Molar Hypomin problem, awareness and acknowledgment of cultural needs is a good start – however, concrete progress towards social good awaits real action across several fronts. We intend to work with indigenous and other minority people to help shape our global attack on Molar Hypomin and childhood decay, once opportunity and resources allow.

Meanwhile, we’ve made a start by supporting needy individuals in low and middle income countries through: (1) our Pay It Forward sponsorship of D3G subscriptions, and (2) half-price discounting for D3G events and allied
education packs (Learning Loop). We’ve also started building a global team
of “D3G cultural attaches” who are knowledgeable in both domains – i.e.
savvy about D3s in context of local cultural needs.

History of The D3 Group

Increasing dental awareness of D3, plus uncertainties regarding their cause and treatment, led to the initiation in 2007 of an informal group of interested practitioners, scientists and public health representatives from Melbourne. Spear-headed by scientist Mike Hubbard and paediatric dentist David Manton, this informal group grew rapidly to include interested parties from elsewhere in Australia and New Zealand. As the figure depicts, a translational vision emerged, covering understanding, treatment and prevention at three operational levels (population, clinic and lab). At a network meeting in 2009, the decision was made to formalise the group as an Australasian, cross-sector network – and so The D3 Group (D3G) was born. Subsequent planning sessions by the Melbourne-based focus group led to agreement that better education was the number-one priority, and that a comprehensive, multi-targeted website would be a major advance in this regard. In 2010, Rebecca Williams (then in her first year of training to be a specialist paediatric dentist) kindly agreed to include co-development of such an online education resource in her doctoral research work. After beta-testing by the target user groups, the final draft website went online on 29th March 2013 and days later was launched to the dental community at meetings of the Australasian Academy of Paediatric Dentistry and the Australian Dental Congress. After responding to suggestions from across the D3G community, the official website launch event was held on 24th August 2013 together with release of a public-friendly media campaign about "Chalky Teeth" (see reports under News and Events).

Our D3 initiative can be traced back to 2003 when Mike Hubbard came to Melbourne with a brief to develop medico-dento-scientific research efforts in the tooth and bone arena under auspice of the Melbourne Research Unit for Facial Disorders, a translational initiative focussed on children. To get the ball rolling, Mike decided to pursue D3 as a worthy clinical problem, and to promote proteomics as a complementary research technology. By 2006, he had a State-wide technology network underway (launched in 2008 as Proteomics and Metabolomics Victoria) and so his attention turned to initiating a parallel translational network for D3. Tiring of the tongue-twisting terms then in common use (i.e. Developmental Dental Defects or DDD, Developmental Defects of Enamel or DDE), Mike coined the term "D3" as a much simpler alternative – and although it will always require explanation, this abstract moniker seems to have struck a chord with the greater dental fraternity and the public alike. In 2013, just a couple of days before public launch of the D3G website, Mike was told by a media consultant that "Molar Hypomin" was too complicated for public consumption (despite being more suitable than "Molar-Incisor Hypomineralisation", the academically favoured term of the day). Recalling a term used by his grandmother, Mike asked "how about chalky teeth?" and the rest is history – the Chalky Teeth media campaign took off, attracting national TV and radio coverage in Australia and over 40 reports around the world (media release, other links). Following further encouragement including broad professional acceptance of D3G's take on "chalky teeth", a dedicated Chalky Teeth Campaign landing site was launched in 2015. Early in 2017, the "We Fight Chalky Teeth" practice network launched in Tasmania – thanks to Garry Nervo for the idea of idiomatically mirroring the global "fight against tooth decay" mantra.

The D3 Group Website

This portal website is intended to help four target groups:

  • Families – D3 sufferers (particularly kids) and their families
  • Community – public health sector and politicians
  • Practitioner – healthcare providers and their support industry
  • Researcher – researcher workers and students

Our design intent has been to tailor each section to its target audience but also to pique curiosity so that cross-exploration of other sections occurs. We have also worked to make the website suitable for chairside use (on tablets such as iPad) as well as on laptop and desktop computers.

Whilst we feel obliged to maintain a reasonable level of curation over this website in its early developmental stages at least (rather than an open wiki style), our overriding goal is to ensure it meets users' needs and reflects consensus understanding of opinion leaders. Accordingly, we strongly encourage input of ideas, suggestions, tips, reinforcements and constructive critique – please email the website administrator (sharon.thed3group@gmail.com) or D3G director (Mike Hubbard) and we'll do our best to please.

The D3 Group Logo

The D3Group Logo

The D3 Group logo, comprising three incisor-like Ds stacked sideways (DDD), signifies that dental defects such as hypomineralisation (chipped blue tooth) typically occur in otherwise healthy mouths and bodies. A colourful connotation is that, as a result of accompanying pain and inconvenience, D3 problems sometimes leave sufferers "feeling blue".
