Comparación de la Muestra Salival y de Nasofaringe en la Detección de SARS-CoV-2 mediante RT-PCR

RESUMEN: El coronavirus tipo 2, SARS-CoV-2, que causa la enfermedad denominada por la OMS como COVID-19, se ha expandido provocando una pandemia desde 2019, sin cura hasta la fecha. El mecanismo de transmisión del SARS-CoV-2 entre humanos es mediante las secreciones generadas durante la respiración y e...

Does Oral Hygiene Influence Salivary pH, Lactate, and IL-1β of Basketball Players During Intense Exercise?

ABSTRACT: This study examined the salivary pH, salivary lactate, and salivary IL-1 β responses from a high-intensity intermittent running test, and the influence of hygiene oral status on these biomarkers in elite adolescent basketball players. Forty-six adolescent players participated. Saliva sampl...

Saliva as a promising biofluid for SARS-CoV-2 detection during the early stages of infection

Abstract Background: Diagnostic testing for coronavirus disease (COVID)-19 is performed using nasopharyngeal swabs. This type of sampling is uncomfortable for the patient, dangerous for health workers, and its high demand has led to a global shortage of swabs. One of the alternative specimens is saliva....

Saliva is a reliable, non-invasive specimen for SARS-CoV-2 detection

Braz. j. infect. dis; 24 (5), 2020
Abstract Background Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the cause of Coronavirus Disease 2019 (COVID-19). Although Real Time Reverse Transcription Polymerase Chain Reaction (qRT-PCR) of respiratory specimens is the gold standard test for detection of SARS-CoV-2 infection, col...

Calcium and phosphorus levels in saliva are influenced by genetic polymorphisms in estrogen receptor alpha and microrna17

Braz. dent. j; 31 (5), 2020
Abstract Homeostasis between salivary calcium and phosphorus is important for maintaining oral health. The aim of this study was to evaluate if polymorphisms in ESR1 (Estrogen Receptor Alpha), ESR2 (Estrogen Receptor Beta) and miRNA17 (microRNA17) are associated with calcium and phosphorus levels in sali...

Monosodium glutamate alters the function and morphology of the parotid gland in Sprague Dawley rats

Int. j. morphol; 38 (4), 2020
Monosodium glutamate (MSG) is a flavor enhancer widely used in the food industry, with obesogenic properties, in addition to causing alterations in the oral cavity. The aim of the study was to observe the morphofunctional changes in the parotid gland after the administration of MSG in rats. 18 newborn ma...

Comparison of saliva and oro-nasopharyngeal swab sample in the molecular diagnosis of COVID-19

SUMMARY BACKGROUND Healthcare personnel are at risk of becoming infected while taking upper and/or lower respiratory tract specimens. Therefore, there is a need for sampling methods that do not risk infecting them. In this study, we aimed to compare the saliva and Oro-Nasopharyngeal Swab (ONS) sampling ...

Consideraciones sobre el diagnóstico de COVID-19 y el papel del diagnóstico salival
Considerations on the diagnosis of COVID-19 and the role of the salival diagnosis

Rev. ADM; 77 (4), 2020
El nuevo coronavirus SARS-CoV-2 es el agente etiológico de la enfermedad por coronavirus de 2019 (COVID-19), convertida rápidamente en una pandemia, emergencia sanitaria y una crisis de salud pública en los países afectados a lo largo de los cinco continentes. El objetivo de la presente revisión bib...

Análisis bibliométrico de la producción científica internacional relacionada con la saliva
Bibliometric analysis of the international scientific production about saliva

El objetivo del presente trabajo fue analizar el panorama científico internacional relacionado con la investigación de la saliva entre los años 2000 y 2018. Se realizó una investigación observacional, descriptiva, retrospectiva, con descripción cuantitativa de los datos, a través del análisis bib...

Changes in salivary composition of chemically dependent subjects

Odontol. vital; (32), 2020
Abstract Chemically dependent subjects may present relevant changes in the volume and composition of salivary fluid because the secretion of the salivary glands is controlled by the parasympathetic and sympathetic system. The aim of this study was to compare the salivary concentration of total proteins, ...
