초록

Objectives: The purpose of this study was to determine the influence of carbonated drinks on acid production in Streptococcus mutans biofilm.
Methods: Fifty one hour-old S. mutans biofilms were formed on hydroxyapatite discs. After select ing of the carbonated drinks (Coca cola, Coca cola zero sugar, Sprite, Sprite zero sugar, and Fanta), as well as negative (water) and positive (1% sucrose) controls for this study, glycolytic pH drop as say was performed using the S. mutans biofilms. The influence of the test agents on acid produc tion of the 51 h-old biofilms was determined by the initial production rate and final concentration of protons, calculated using the pH values at 0-30 min and 120 min, respectively.
Results: The pH values of the carbonated drinks ranged from 2.4 to 3.1. Sugar-free carbonated drinks and the negative control maintained the pH of acid produced by S. mutans biofilms above thecritical pH. The sugar-added carbonated drinks and the positive control decreased the pH below the critical pH due to the acid production of S. mutans biofilms. Overall, sugar concentration in carbon ated drinks was closely related to acid production in S. mutans biofilm.
Conclusions: These results suggest that sugar-added carbonated beverages should be considered for their role in dental erosion and dental caries, while non-sugar-added carbonated beveragesshould emphasize their role in dental erosion rather than dental caries.
