Abstract

AIM:

This study aimed to evaluate the erosive potential of twenty beverages (8 carbonated drinks and 12 packaged fruit juices).

MATERIALS AND METHODS:

Twenty-one sound permanent freshly extracted teeth were segmented into small enamel slices and stored in normal saline. The titratable acidity of each experimental drink was measured as the amount of 0.1 N sodium hydroxide (NaOH) required to raise pH to 5.5 and 7. The enamel specimens were incubated in freshly collected human saliva for 3 hours. One enamel slice was immersed in each beverage and percentage weight loss in the enamel slice was calculated after 6 and 24 hours intervals.

RESULTS:

The titratable acidity values of the experimental drinks ranged from 0.2 to 5.6. The mean titratable acidity values of the packaged fruit juices were higher than carbonated drinks. A significant difference (p < 0.0 5) was found in the percentage weight loss of enamel specimens after 6 and 24 hours immersion in the carbonated drinks than packaged fruit juices. Apple juice followed by thumps up were found to be the most erosive drinks with the least effects of Miranda and Guava juice.

CONCLUSION:

Most of the beverages tested in this study showed erosive potential. The carbonated drinks caused significant dental erosion.

CLINICAL SIGNIFICANCE:

Individuals at risk for beverages-associated erosion, particularly those with high intakes or decreased salivary flow, should be provided preventive guidance regarding habits of beverages intake. Specific dietary recommendations for the prevention of dental erosion may now be developed based on the patient's history of beverage consumption.
