A Comparative Evaluation of Dental Erosion Caused by Tetrapacked and Aerated Beverages: An In-Vitro study
Keywords:Beverage, Dental erosion, Enamel
Introduction: Dental erosion is an evolving concern with the food market globalization. In a rapidly
developing nation as India, beverage consuming behavior has significantly increased. There is free
access to new foods and beverages even in the neighborhood grocery stores and they are perceived as
modern and healthy. Extrinsic erosion appears to be a growing problem as a result of overconsumption
of soft drinks or fruit juices or both. Materials and Methods: Freshly extracted premolars were
treated with H202 for 24 hours and weighed with ‘Essae FB-200’ with a readability of 0.001 gram. The
beverages were grouped into 2 categories, 1- Natural or tetra-packed beverages, 2 - aerated beverages
and a control. 20ml of each beverage was taken and the pH was measured. The tooth was immersed in
each of the beverage and pH were noted 4th hourly for 48 hours accounting for sipping the beverage
for 5 minutes every day for 1.5 years. The weight of the tooth was rechecked after 48 hours. Results:
The mean pre-treatment pH of category 1 was 5±1.33 and that of category 2 was 4.66±1.32. There is
no significant difference in the mean loss of weight between the two groups (p-value 0.94) there is no
significant difference in the mean change of pH between the two groups (p-value 0.26) Conclusion:
The objective erosive liability of tetra-packed and aerated beverages on the dental enamel was found
to be similar. However, natural fruit juices showed nil to negligible objective signs of dental erosion.
