Abstract

Aim: The purpose of this study was to evaluate changes in the salivary pH after the consumption of different beverages in children at different time intervals. Material and Methods: In this cross-over, single blinded, eighty children between the ages of 7 to 12 years having a strict vegetarian diet were included in the study for consumption of four different fruit juices (i.e. Guava, Orange, Apple, Pomegranate) by dividing them into 4 groups based on caries experience selected. The endogenous pH of the salivary samples was measured at the baseline and after consumption of the fruit juices at 5, 15 and 30 minutes. Data was collected separately for simple fruits, fresh fruit juices and processed juices. The intrinsic pH of fruit juices was noted by the digital electronic pH meter. The collected Data were statistically analyzed by using ANOVA. Results: The processed fruit juices caused acidity in saliva than fresh juices and fruits after 5 mins. After 15 mins of intake of juices and fruits, the pH of fresh fruit juices moved towards neutral pH while that of processed fruit juices was found to be still acidic. After 30 mins, pH tends to be alkaline for both fresh and processed juices. There was the least change in salivary pH with the use of pomegranate fruits and juices during the whole study. Conclusion: Pomegranate has less changing effect on saliva pH than all other fruits used in the study and processed fruit juices have a significant influence on the change of salivary pH. The use of fresh fruit juices can be suggested in future.
