Stability Of Salivary pH After Use Of Oral Antiseptics And Carbonated Beverages

Abstract

Acid-base balance of saliva is an important factor for oral health because lowering the pH is associated with the development of oral diseases. The physiological value of saliva pH is in the range of 6.2-7.6. A saliva sample was taken before consuming the liquid and four samples at a certain time interval after that, in 10 volunteers. PH was determined using a digital pH meter (Lutron Electronics Enterprise pH meter). The tested liquids lead to an initial decrease in pH which after 2 hours approaches the values before the experiment. Sweetened carbonated drinks have the most significant effect on the pH of saliva.
