Abstract


Objective: To evaluate salivary flow and buffer capacity by means of mechanical and chemical-mechanical stimuli, through the use of chewing gums. Material and Methods: The study was a cross-sectional study with 12 volunteers, divided into three groups, in three phases: Group A: paraffin gum; Group B: Chewing gum without sucrose, flavored (Trident®); Group C: Flavored chewing gum, without sucrose and amorphous calcium casein-phosphate phosphopeptide (Trident Total®). The stimulated total saliva was collected after 5 minutes of mastication of one of the products and the volume was expressed in mL / min. The same sample was submitted to pH measurement with the use of a digital potentiometer, where the results were classified in normal buffer capacity (final pH between 5.0 and 7.0) or low (final pH <4.0). The results were evaluated regarding the normality of the sample distribution (Shapiro-Wilk test), Analysis of Variance (ANOVA) and Tukey's test. Results: Chewing gums increased the salivary flow of the volunteers, when compared to the control group (paraffin) (1.53 mL / min), differing statistically from the group, although there was no difference between Trident® (2.09 mL / Min) and Trident Total® (2.06mL / min). Regarding the buffer capacity, the values obtained were 6.94 (paraffin), 6.99 (Trident®) and 6.93 (Trident Total®), with no difference between groups (p = 0.713). Conclusion: It was concluded that chewing gums, with and without CPP-ACP, increased the salivary flow in relation to the control group. In relation to buffer capacity the values obtained for chewing gums with and without CPP-ACP, are shown to be within the normal range.
