하루 생수 2L섭취에 따른 타액 분비량과 타액 pH의 상관관계

The Relation of Amount of the Saliva Secretion Rate and Saliva pH on Taking 2 Liters of Water Per a Day

Objectives: The purposes of this study were 1) to investigate how the saliva secretion rate and saliva pH affect the consumption of 2 L of bottled water per day and 2) to obtain basic data to suggest the proper contents and direction of water intake education to help prevent and treat dental caries. Methods: The study participants were 20 women in their 20s in B area who did not drink 2 L of water per day. This work measured the amount of water consumed daily over five weeks, saliva secretion rate, and saliva pH and then examined the correlation between factors. Results: Before the experiment, the water intake, saliva secretion rate, and pH were 793.63 mL, 2.97 mL, and 6.63, respectively. At the end of the experiment, the water intake, saliva secretion rate, and pH were 2,040.92 mL, 5.00 mL, and 7.43, respectively. The mean water intake, saliva secretion rate, and pH were 1,950.24 mL, 4.27 mL, and 7.18, respectively, and the pH increased significantly each week (p<0.05). The saliva secretion rate and saliva pH were positively correlated with the increase in water intake, but the correlation was not significant. As the saliva secretion rate increased, the saliva pH increased, and it was statistically significant (p<0.01). Conclusions: The saliva secretion rate and saliva pH increased significantly with the water intake (p<0.05), and the saliva secretion rate and saliva pH were positively correlated with water intake. Encouraging frequent and large amounts of water intake from adolescence through oral health education may help improve oral hygiene through the effect of increased saliva.
