Abstract
Objective: To assess and compare the erosive potential of commercially available beverages and to evaluate the relationship between mineral loss and physiochemical properties (pH and titratable acidity) of different beverages. Material and Methods: Seven commercially available beverages [4 soft drinks, 1 chlorhexidine mouthwash and 2 controls (Amul milk and human saliva)] were tested. The pH and tritratable acidity of the beverages was determined. Fifty-six human premolars were sectioned into enamel and root surface (total 112 specimens) by using diamond-cutting machine. The specimens were immersed in each beverage for 24-hour intervals at 37 0 C. The weight loss of the specimens and mineral loss (calcium, phosphorus and fluoride) was determined at pre and post immersion and was subjected to statistical analysis at p<0.05 level of significance. Results: All beverages included in this were acidic. Nimbooz exhibited significant (p<0.05) weight loss compared to all other beverages. Fanta shows significantly (p<0.05) high loss of phosphorus and calcium for enamel and root surface respectively. There was a week correlation with pH and tritratable acidity and loss of minerals. Conclusion: The erosive potential of Fanta and Nimbooz was significant compared to other beverages. However, it must be considered that there are numerous factors, which may influence the erosion rate in the intra oral environment; hence the result of this in vitro study should be applied with caution.
Highlights
Dental erosion is an irreversible loss of tooth structure due to dissolution of the calcified dental tissues by chemicals without the involvement of microorganisms [1,2]

In recent years there has been an enormous increase in the beverages consumption, and this is no longer confined to children but is being carried forward into adult life [10,11] in vitro investigation was done to assess the erosive potential of 4 commercially available beverages, chlorhexidine mouthwash, milk and human saliva on enamel and root surface
Summary
Dental erosion is an irreversible loss of tooth structure due to dissolution of the calcified dental tissues by chemicals without the involvement of microorganisms [1,2]. Apart from dental caries and periodontal diseases, dental erosion is considered as the growing oral health problem affecting both children and adults [3,4]. This is due to the change in the eating habits, mostly the gaining popularity and increase consumption of acidic beverages over recent years. The severity of erosion is related to several factors, including the chemical properties of the erosive medium, and the frequency and method of contact between acid and tooth. Depending upon the severity and length of exposure, the dental erosion varies from reduction in teeth size to total destruction of the dentition
