26 AUGUST 2010 EROSION IN PROFESSIONAL WINE TASTERS: an occupational health issue? INTRODUCTION The Australian wine industry is one of the world's top wine producers with an export value of nearly $2.5 billion in 2009, representing the second largest unprocessed primary products after wheat exports.1 There are over 2,000 wineries across the country2 and the principal production areas are South Australia, New South Wales and Victoria.3 The industry directly employs around 31,000 people,2 several thousands of whom are estimated to be professional wine tasters. Professional wine tasters, particularly winemakers and judges, are at risk of developing dental erosion, and wine erosion has been identified to be a potential occupational hazard. Wine judges on average taste up to 200 wines per day for nearly five days a week, several times a year.4 Wine is acidic in nature (pH 3.0 -- 4.0), containing highly erosive organic acids such as tartaric, maleic and lactic acids.5, 6 White wines are more erosive than red wines,7 and immature and sparkling wines tend to be more acidic than matured wines. Rees et al.8 tested the erosive potential of 11 different white wines from seven different countries in vitro and noted that the degree of erosion was similar to, or greater than, that of orange juice. Wine acid erodes surface tooth structure and also softens a shallow subsurface layer. In vitro findings indicate that enamel microhardness decreases significantly two minutes after exposure to red wine.9 The softened subsurface layer is susceptible to erosive tooth wear, referring to wear of eroded lesions by mechanical factors such as toothbrush abrasion or attrition. Erosive tooth wear becomes cumulative over time and an extensively worn dentition can give rise to many problems, including dentinal hypersensitivity, pulp exposure and loss of occlusal vertical dimension. Such problems can affect quality of life and present treatment dilemma to clinicians. Complex restorative management of the worn dentition may also impose a financial burden to both the individual and the healthcare system. In this context, early signs of erosive tooth wear should be recognized and preventive strategies implemented. The present article will briefly summarize some examples of extensive wine erosion published in the literature, and will discuss risk factors and preventive management tailored for wine tasters. Topics on causes, signs and symptoms of erosive tooth wear will be briefly discussed here, but readers should refer to other publications10-14, 15 for further details. committee report
