Inorganic component of saliva during fasting and after fast break

Abstract

Oral health is closely related to salivary components. Saliva consists of water, inorganic and organic materials. Fasting changes one’s meal and drinking time that in turn can affect the environment in oral cavity, including inorganic componenet of saliva. The purpose of this study is to determine the inorganic component of saliva during fasting and after fast break. The study is an observational analytic (longitudinal/follow-up study) conducted in Hasanuddin University dental hospital in July 2015. The sampling method is purposive sampling with the entire population of Dental Public Health section students, who are 35 people with 16 research subjects who fullfill the criteria of the study. Samples were tested in the laboratory using Atomic Absorption Spectrophotometer (AAS) in part per million (ppm) units. The data is analysed by paired t-test with SPSS version 17.0. The result shows that concentration of inorganic components (calcium, phosphate and potassium) in the saliva decreased significantly after fast break (p<0.05). Sodium shows decreased insignificantly after fast break (p=0.190) and magnesium increased insignificantly after break fasting (p=0.615). The concentration of calcium, phosphate, potassium except sodium decreased significantly after fast break, whereas the concentrations of magnesium were not significantly increased after fast break.

A review of salivary composition changes induced by fasting and its impact on health

“…Other time restricted fasting studies such as by Illahi et al [50] found that salivary pH increases, while Selviani et al [53] found inorganic components like potassium and magnesium decrease. There were no significant changes in salivary sodium [53]. Some of these results agree (within the error) with those of TRF reported by Rahim and Yaacob [23].…”

“…We shall now comment on the effect of fasting on the production of some saliva components as given in Table 2. There are reports on saliva composition under fasting conditions [23,40,50,53,60,88,100,101], but the data reported are relatively scarce and incomplete. Moreover, the fasting regimes differ from author to author.…”

“…Moreover, the fasting regimes differ from author to author. The commonly reported regimes are fasting without food and water for a given period [23,50,53,101], intermittent fasting [88], and fasting during the month of Ramadhan, i.e. RF [40,60,100].…”

Comparison of efficacy rinsing with cocoa seed extract, green tea catechins extract and lime extract to salivary ph in children suffering ECC (Early Childhood Caries)

“…The role of saliva is not only for the mastication process but also to protect the tissue inside the oral cavity. 5,6 In normal circumstances, salivary pH is about 6.8 to 7.2 but some types of carbohydrates are converted by bacteria and result in a decreased pH of the saliva. 7 Natural ingredients from plants in Indonesia can be used to inhibit this process.…”
