Perbedaan Laju Alir dan Derajat Keasaman Saliva pada Peminum Minuman Ringan dan Peminum Susu (Systematic Literature Review)

Abstract

Saliva is a complex fluid in the oral cavity, consisting of a mixture of major and minor salivary gland secretions with a salivary pH ranging from 6.5-7.4. Several factors cause changes in salivary pH, including salivary flow rate, oral flora normal, salivary buffer capacity, and food and beverages consumed; one of which is milk and soft drinks. Milk contains many food substances such as carbohydrates, proteins, minerals, and vitamins. Soft drinks do not contain alcohol, in powder or liquid form containing food ingredients and other additives both natural and synthetic packaged ready for consumption. The purpose of this study was to determine the difference in flow rate and degree of acidity (pH) of saliva in soft drink drinkers and milk drinkers. The research method used is Systematic Literature Review (SLR) with 3 journal databases namely PubMed, Science Direct and Google Schoolar. Based on the literature search, 322 literatures were obtained, which were checked for duplication of articles with Mendeley software. Screening was carried out on the literature based on the title and abstract so that 14 literatures were obtained that met the eligibility and were analyzed further. The results show that there are two literatures stating that there is an increase in salivary flow rate in soft drink and milk drinkers. Seven literatures state that there is an increase in the degree of salivary acidity in soft drink drinkers. Five literatures stated that there was a decrease in the degree of salivary acidity in milk drinkers. The conclusion shows that the condition of salivary flow rate in soft drinkers and milk drinkers increases. The level of salivary acidity in soft drink drinkers is higher than milk drinkers.
