Effectiveness of Rinsing Water and Chewing gum on Restoring pH of Saliva After Drinking the Drinking Yogurt
Objectives: To compare the duration in restoring the salivary pH to normal level by four strategies after drinking a drinking yogurt.
Methods: Subjects with stratification by sex were randomly allocated into 4 different strategies after drinking a drinking yogurt: A-plain water rinsing, B-gum chewing, C-plain water rinsing follow by gum chewing, and D-do nothing. The unstimulated salivary flow rate, pH and buffer-capacity were measured at baseline and at 0, 5, 10, 15, 30 and 45 minutes after drinking 50 ml of drinking yogurt and the assigned strategies. , The durations in restoring the salivary pH to normal level and patterns of pH changing were evaluated by ANOVA and Repeated Measures ANOVA (RMANOVA) using SPSS for windows version 22.0 (IBM Corp., USA).
Results: The 52 Buddhajak-Wittaya-School-student with 14.18(0.78) years of age were recruited into the study. 24 of them were male. 13, 14, 12, and 13 students were allocated into group A, B, C, and D, respectively. The mean (SD) durations in restoring the pH to normal levels of group A, B, C, and D were 22.69(28.26), 26.43(30.66), 10.83(8.48), and 10.0(4.56) respectively. Group-B and Group-C indicated lowest drop of pH within 10 minutes after drinking the drinking yogurt. Group-A revealed similar pattern as Group-D with slightly lower change of the salivary pH.
Conclusions: Different strategies after drinking the drinking yogurt indicated no significant different (ANOVA, p-value = 0.141) of durations in restoring the pH to normal levels with different salivary pH at each time point (RMANOVA, p-value = 0.046).
