Abstract
Acidic beverages can produce erosion of natural dentition in humans when consumed frequently or excessively. The aim of the present study was to investigate the flexural strength of Zirconia after immersion in acidic drink. Zirlux® anterior multi (Zirlux®, Zahn Dental, Langden, Germany) Zirconia was tested. Thirty specimens of Zirconia were divided into 3 groups (n=10): specimens of group 1 were used as a control group that were immersed in ionised water for 7days, specimens of group 2 were immersed in 50 ml of Coca-Cola for 4 days, and specimens of group 3 were immersed in 50 ml of Coca-Cola for 7 days. The flexural strength was measured for each material using an Instron Universal Testing Machine. The Data was subjected to statistical analysis. After acidic drink immersion, no significant differences were reported between control group 1, group 2 and group 3. After immersion periods of 4 and 7 days, there was no statistical reduction in flexural strength value due to immersion in acidic drink.
