Abstract
Objectives: This study examines the pH and titratable acidity of pomegranate drinks sold in Korea to identify the risk of dental erosion, and to provide basic data for oral health when consuming such drinks.
Methods: The experiment included 5 groups: As experimental drinks, Sunkist pomegranate (Group A), Beauty liked pomegranate (Group B), Pomegranate juice 100 (Group C) were selected, and Jeju Samdasoo and Coca-Cola were selected for negative and positive controls. The components of the experimental beverage were analyzed, and the degree of erosion was measured using the Vickers hardness number (VHN) and by scanning electron microscope images.
Results: When comparing the surface microhardness before and 30 minutes after beverage immersion, there was a significant difference in the positive control group, Group A, Group B, and Group C (P<0.05), while there was no significant difference in the negative control group (P>0.05). The difference in surface microhardness (ΔVHN) was found in Group C (-117.33±17.41), Group A (-112.90±15.19), the positive control group (-103.80±13.23), Group B (-90.82±24.60), and the negative control group (-13.44±14.60), in that order. The positive control group, Group A, Group B, and Group C showed a significant difference from the negative control group (P<0.05), and Group B showed a significant difference from Group A, and Group C (P<0.05), whereas Group A, Group B, and Group C did not differ significantly from the positive control group (P>0.05).
Conclusions: This study found that the low pH and high titratable acidity of commercially available pomegranate drinks can potentially cause dental erosion. Therefore, it is imperative to provide dietary guidance so that consumers can recognize the possibility of dental erosion when consuming pomegranate drinks and manage their oral health.
