Repairing teeth together

Across Japan teeth are being made stronger with chewing gum and other products using an ingredient discovered in Australian dairy milk.

Now an innovative Japanese company is taking the Australian discovery to dental surgeries around the world.

“Our discovery was based on milk, to develop a delivery system of calcium phosphate to make teeth stronger,” says Eric Reynolds, from The University of Melbourne.

Clinical trials of the chewing gum showed that it helps stop tooth decay and helps reverse early stages of tooth decay.

“The Recaldent chewing gum was very successful in Japan and the leading dental supply company in Japan, GC Corporation, then became interested in the technology.”

“We’ve developed materials for repair of tooth decay and damage but now we’re focusing on prevention and protection collaborating with Melbourne University,” says Satoshi Tosaki from GC Corporation.

“One of those products is a cream, in Australia it’s called Tooth Mousse, that’s sold to dentists to strengthen patients’ teeth and that’s now sold in more than 50 countries worldwide,” he says.

“I’ve really enjoyed working with GC because I’ve learnt a lot from them in terms of business. But I think the most gratifying thing is that their products actually help people, and substantially reduce the burden of oral disease,” Eric says.

Distilling value from industrial waste

Hot and salty water is a common by-product of industries such as textiles, food and dairy production. But new technology that allows this water to be purified, collected and re-used on site has been developed by Victorian scientists.

Their compact module, smaller than the size of a human, can transform a wasteful industrial operation into an efficient process that recycles energy, water and materials.

“We’ve calculated that our module can reduce water use by more than 90 per cent in some industrial settings,” Professor Mikel Duke says.

Dairy stem cells a world first

Embryonic stem cells from cattle can now be stored in mass in the laboratory, paving the way for advanced breeding developments in dairy cattle and other livestock.

These new ways of efficiently isolating and maintaining cells provide scientists from Australia’s Dairy Cooperative Research Centre with the raw materials to investigate a range of stem cell applications.
