Effects of carbonated beverage and fruit juice on salivary pH among children in orphanage of Bareilly city: an in vivo study

Abstract

Background: High degree of urbanization and economic development have resulted in rapid changes in diet and lifestyles, because of which there is a tremendous increase in prevalence of dental caries in developing countries. The aim of the study is to assess the acidogenic potential of commonly consumed carbonated beverage and commercially available fruit juice at various time intervals among orphan children. Methods: This is an in vivo study in which 60 orphan children were included. Two beverage groups (carbonated beverage and fruit juice) were tested for salivary pH before having respective drinks (baseline) and after having drinks at specific time intervals (immediately after, after 15 min and 30 min). Intra-group and inter-group comparisons were done using Friedman test and Mann Whitney U test. Results: Both the groups showed decrease in salivary pH after consumption and recovery of salivary pH to baseline value after 30 min. Conclusions: Beverages produce a remarkable drop in the salivary pH as they contain organic acids and sugars but saliva by virtue of its buffering capacity nullifies this effect and after some time it comes to normal.

Effect of Carbonated Beverages on Salivary pH and Dental Caries in a Sample of Egyptian Children “A cross-sectional study”

“…However, after 20 minutes, the pH commenced to rise and a constant rise was seen after 30 minutes. Agrawal et al 23 found same results where the buffering capacity of the saliva nullified the pH drop caused by intake of carbonated beverages in only 30 minutes. A comparison between the intakes of cold carbonated drinks and packed fruit juices revealed a higher drop in the salivary pH after consumption of carbonated beverages in comparison to packed fruit juices.…”

Assessment of early childhood caries using ICDAS and Snyder caries activity test among preschool children: a cross-sectional study

“…Hwang et al [43] evaluated the pH before and after intake, according to the beverage type, using the modified SCAT; they found a lower pH in lactic acidic beverages than in alkaline or carbonated beverages. In addition, there were studies on changes in the pH of saliva and tooth demineralization depending on the type of beverage [44][45][46]. No association between d1 and d2 with SCAT was observed.…”
