Introduction: recent shift in diet pattern and frequent use of beverages cause tooth erosion to be a growing dental problem. Are glass ionomer and composite a solution against tooth erosion? Aim: What is the erosive potential of cola, energy drink and orange juice to glass ionomer and composite? Materials & methods: 90 composite and glass ionomer samples were fabricated and stored in artificial saliva for 24 hours. After that the samples were randomly divided over cola, energy drink and orange juice (n=15 per material per liquid) and immersed in 100 ml liquid for four days and four hours. The erosive effect of these drinks on the surface microhardness, the material loss (weight loss and height loss) and the surface roughness of the restoration materials is measured by using the Knoop hardness test, profilometer and four decimals balance. Statistical analysis was done by mixed repeated measures ANOVA, Tukey’s test en independent samples t-test with a p-value of p < 0,05 Results: Composite has a higher start hardness than glass ionomer. The hardness of composite decreased and the weight increased significantly after immersion. There was no difference between the drinks. The surface roughness of composite increased significant after immersion in cola. For glass ionomer, the weight loss, height loss and increasing surface roughness are significant after immersion in cola and energy drink. The weight loss after immersion in energy drink compared to immersion in cola and orange juice is significant different. There were significant differences observed in height loss and decreasing surface roughness between all drinks. Conclusion: These acidic beverages cause erosive wear on composite and glass ionomer. All drinks have negative effect on the hardness of composite. As for glass ionomer, there is a significant material loss (weight and height loss) and increasing of surface roughness after immersion in cola and energy drink. In addition, composite absorbs water. Material selection is important and should be considered when treating patients with tooth erosion. This in vitro research has showed that composite provides better wear and erosion resistant than glass ionomer.
