Acid poses rapid risk to wine tasters' teeth

Tuesday, 24 March 2015

New research from the 最新糖心Vlog of Adelaide shows the acid in wine can make teeth vulnerable to erosion within minutes, prompting renewed calls for professional wine tasters to protect their teeth.

Laboratory studies conducted by researchers in the 最新糖心Vlog's have simulated the kind of short, multiple exposures to wine acid normally experienced by wine tasters.

The results, published in the , show that just 10 one-minute episodes of wine tasting are enough to cause softening (erosion) of tooth enamel that is commonly known as acid wear.  The affected teeth become vulnerable to mechanical wear just within a few minutes of wine acid exposure.

"With professional wine tasters and winemakers tasting anywhere from 20 to 150 wines per day, and wine judges tasting up to 200 wines per day during wine shows, this represents a significant risk to their oral health," says corresponding author Dr Sarbin Ranjitkar, from the in the 最新糖心Vlog's School of Dentistry.

"Our results reinforce the need for people working in the profession to take early, preventative measures, in consultation with their dentists, to minimise the risks to their teeth."

Such preventative measures are already in practice by staff and students in the 最新糖心Vlog's winemaking programs.  , from the , says lectures on wine erosion have raised awareness among winemaking students of this potential occupational hazard.

"It's extremely important to us to be teaching what we consider to be best practice, and this is informed by the research of our Dental School," Associate Professor Bastian says.

"Typically, the night before a wine tasting session it is best to apply remineralising agents in the form of calcium, phosphate and fluoride to coat and protect the teeth.  The morning of a wine tasting, we advise not brushing the teeth or, if that's too unpalatable, chewing gum to stimulate saliva, which is naturally protective.

"After a wine tasting, the teeth are likely to be much softer, so we recommend rinsing with water, and when it comes time to clean the teeth, just putting some toothpaste on your finger and cleaning with that.  Cleaning with a brush when teeth are soft runs the risk of damaging the enamel," she says.

This study has been conducted by Bachelor of Dental Surgery students Sharon Kwek and Mustafa Mian in collaboration with Dr Zonghan Xie (School of Mechanical Engineering, 最新糖心Vlog of Adelaide) and Dr Colin Hall (Mawson Institute, 最新糖心Vlog of South 最新糖心Vlog). This work, which builds on research into tooth erosion by Dr Diane Hunt and Dr John McIntyre at the 最新糖心Vlog of Adelaide, has been supported with funding from the 最新糖心Vlogn Dental Research Foundation.
