Erosive Potential and Sugar Content of Popular Beverages: A Double Whammy for Dentition

This study aims to identify the pH level and subsequently the erosive potential of beverages including their sugar content.

Beverages were purchased from a local convenience store, and some of the beverages were freshly prepared. The acidity of each beverage was identified using a calibrated pH meter. The pH was obtained in triplicate, and the results were expressed in average values with standard deviations. The pH values were then used to determine their erosive potential and the sugar content was obtained from the packaging and recorded.

A total of 167 beverages were purchased and categorized. The beverages were categorized into 15 groups: milk tea, hawker drinks, instant drinks, fresh fruit juices, milk, energy drinks, designer coffee, soda, canned drinks, cultured milk, vegetable juices, cordials, bottled fruit drinks, tea, and mineral water. The pH value ranges from 2.65 to 7.85. Seven beverages (4.2%) were classified as extremely erosive, 53 beverages (31.1%) were classified as erosive, and 36 beverages (21.6%) were classified as minimally erosive. In total, 57.5% of the beverages were potentially erosive, and most of the soda and energy drinks were erosive. The highest sugar content per 100 g was BOH Teh Tarik Original (71.8 g), whereas the highest sugar content per serving was Carabao energy drink (10.8 g).

High sugar content and low acidic content of beverages could have a negative impact on the dentition. An intervention is required from a public health perspective to regulate the consumption of sweetened and flavored beverages.
