Method: Beverages were tested for their individual pH. Net weight loss was recorded following a 24-hour incubation period. Clinical effects were also determined by scanning electron microscopy
Result: The results demonstrate that pre-mixed alcoholic beverages possess pH’s below the critical pH of 5.5 and possess the ability to cause erosion. Gordon’s Gin and Schweppes Indian Tonic Water, Vodka Cruiser Mixed Berry Sugar Free, and Elevate Alcoholic Soda with Guarana had pHs of 2.2, 3.2 and 3.6 respectively. All samples showed a significant decrease in net loss of tooth structure. The greatest reduction was seen in specimens incubated in Gordon’s Gin (4.71%), followed by Vodka Cruise (3.55%) and Elevate (1.13%). Scanning electron microscopy showed that Gordon’s Gin and Vodka Cruiser showed similar etching patterns with numerous large porosities whereas Elevate showed small multiple porosities.
Conclusion: This study demonstrates that commonly consumed pre-mixed alcoholic beverages possess low pHs and the ability to cause dental erosion.
