The Effect of Black Coffee and Tea Consumption to Saliva Degree of Acidity in Preventing Tooth Decay

Abstract

Background: The degree of acidity (pH) is one important factor that plays a role in the prevention of dental caries and tooth demineralization. Being most commonly consumed, black coffee as well as tea have antibacterial effects, so effective as anti-plaque and prevent decreasing pH saliva. The Objective: This study aims to determine the effect before and after consumption of black coffee and black tea in determining the degree of acidity in saliva. Method: The research was a quasi-experimental research with the cross-sectional approach. The design in this study used a pretest and posttest taken 40 respondents. Result: The results showed that the saliva acid level (pH) before the consumption of black coffee and black tea is different. The change in average alivary pH before and after consumption of lack coffee was 0.4 and 0.3 for black tea. Conclusion: The conclusion between black coffee and black tea consumption tends to affect the salivary of pH. Based on the results of the study, people are advised to consume black coffee and black tea a maximum of 2 cups in a day.
