Evaluation of alpha amylase and peroxidase in saliva of pregnant women

Journal of Baghdad College of Dentistry, 2023
Background: Pregnancy is a natural physiological state that involves several biochemical modifications. Saliva is consisted of many types of proteins such as salivary alpha amylase and salivary peroxidase that might be affected by pregnancy.

Salivary Alpha-Amylase Activity and Salivary Flow Rate in Young Adults [PDF]

The Open Dentistry Journal, 2013
The secretion of salivary alpha-amylase (sAA) is more associated with psychoneuroendocrinological response to stress than with the flow rate and age. The aim of this cross sectional study is to build an explanatory model based on patterns of relationship between age 20-39 in resting and stimulated saliva under no stressful condition in healthy ...

Salivary Alpha-Amylase Correlates with Subjective Heat Pain Perception [PDF]

Pain Medicine, 2016
Abstract Objective. Self-reports of pain are important for an adequate therapy. This is a problem with patients and infants who are restricted in providing an accurate verbal estimation of their pain. Reliable, real-time, economical, and non-invasive physiological correlates might contribute to a more comprehensive description of pain.

Effect of alpha amylase on early childhood caries: a matched case-control study

Brazilian Dental Science, 2013
Objectives: There are a few studies addressing the relationship between salivary alpha-amylase and dental caries. This study was implemented in order to investigate the effect of salivary alpha-amylase level on early childhood caries (ECC).

Impact of Physical Stress on Salivary Buffering Capacity [PDF]

, 2016
Background: Saliva has many properties and the buffering capacity is important for the neutralization of oral fluids. It is unclear whether stressful conditions directly affect salivary buffering capacity, and we investigated the impact of physical ...

Effects of filtration and alpha-amylase depletion on salivary biochemical composition measurements.

PLoS ONE, 2023
The effects of filtration (F) and alpha-amylase depletion (AD) were assessed in n = 34 saliva samples. Each saliva sample was split into three aliquots and treated as follows: (1) no treatment; (2) 0.45μm commercial filter; and (3) 0.45μm commercial ...

Impact of calcium on salivary α-amylase activity, starch paste apparent viscosity and thickness perception [PDF]

, 2011
Thickness perception of starch-thickened products during eating has been linked to starch viscosity and salivary amylase activity. Calcium is an essential cofactor for α-amylase and there is anecdotal evidence that adding extra calcium affects ...

Characterization of salivary alpha-amylase binding to Streptococcus sanguis [PDF]

Infection and Immunity, 1989
The purpose of this study was to identify the major salivary components which interact with oral bacteria and to determine the mechanism(s) responsible for their binding to the bacterial surface. Strains of Streptococcus sanguis, Streptococcus mitis, Streptococcus mutans, and Actinomyces viscosus were incubated for 2 h in freshly collected human ...

Electrophoretic Detection of Salivary .ALPHA.-Amylase Activity.

The Journal of Nihon University School of Dentistry, 1992
Fresh samples of human whole saliva containing approximately 20-40 micrograms protein were analyzed using SDS-polyacrylamide slab gel electrophoresis systems. More than 20 protein bands were revealed by Coomassie Brilliant Blue R 250 staining. Some of the protein bands were shown to be glycoprotein-positive with PAS (periodic acid-Schiff) reagent.
