Complete Blood Count and saliva parameters as an indicator for infected patients with coronavirus covid-19

Abstract

Background: Coronavirus, which causes respiratory illness, has been a public health issue in recent decades. Because the clinical symptoms of infection are not always specific, it is difficult to expose all suspects to qualitative testing in order to confirm or rule out infection as a test. Methods: According to the scientific studies and investigations, seventy-three results of scientific articles and research were obtained using PubMed, Medline, Research gate and Google Scholar. The research keywords used were COVID-19, coronavirus, blood parameters, and saliva. Results: This review provides a report on the changes in the blood and saliva tests of those who are infected with the COVID-19.COVID-19 is a systemic infection that has a substantial influence on the hematological system and hemostasis, thus deviations from normal levels of laboratory tests, including the blood and saliva test show that specific testing for detecting COVID-19 infection is required. Conclusions: The blood and saliva tests aid in the clinical monitoring of the patient's health. It has advantages such as the following: it has non-invasive properties, low cost, and good stability, addition to minimum risk of infection transport.

An Updated Review of Salivary pH Effects on Polymethyl Methacrylate (PMMA)-Based Removable Dental Prostheses

“…Moreover, patients with xerostomia and hyposalivation are more prone to have low salivary pH; this is due to the diminished buffering effect of saliva when it is produced in a low amount. The imbalance in buffering effect resulted in more microorganisms in the oral cavity, which subsequently increases the medium acidity even more [30]. Sjögren's syndrome and chemotherapy also resulted in acidic pH [46].…”

“…Saliva is the first natural biologically produced fluid coming into direct contact with artificially produced dental restoration [29]. Saliva is a clear fluid glandular secretion of the salivary glands that is constantly excreted and poured into the oral cavity via secretory duct openings [30]. Saliva serves many functions, such as keeping the mouth moist and comfortable, and helping in chewing, tasting, and swallowing.…”

“…Salivary pH could range from 5.3 in case of low flow to 7.8 in highest flow [29]. Salivary pH can be affected by several factors, including the consumption of different types of food and beverage such as sugar, orange juice, and pastries [30].…”

“…Gastroesophageal Reflux Disease (GERD) is an accustomed affection, with approximately 50% of all adults reporting reflux symptoms at some time during their lives [31]. In contrast, the alkalinity of the saliva can be increased due to some types of food or diseases such as problems in the liver and digestive functions including pancreas secretions and enzyme production [30].…”

“…The continuous interaction between saliva and removable prostheses necessitates evaluating the effect of salivary pH on mechanical and surface properties of denture base resins, denture lining materials, and RPD framework materials. This is significant, since these materials are subjected to different salivary pH levels on a daily basis, either due to consumption of certain types of acidic or alkaline beverage or diseases [30]. The purpose of this systematic review is to evaluate the effect of different salivary pH on the properties of removable dental prostheses (RDP).…”
