alpha amylase/dental caries

Thirty-eight young adults participated in the study. They were divided in a caries-inactive group, a low caries activity group and a moderate to high caries activity group. Total cultivable bacteria, Streptococcus salivarius, and S. mutans in plaque and saliva were quantitated on TSA, MS, and MSB

High-performance hydrophobic interaction chromatography (HIC) and capillary zone electrophoresis (CZE) were utilized in an effort to find the correlation between the composition of some isoenzymes of human salivary alpha-amylase (HSA) and dental caries. The mixture of more than three isoenzymes of

OBJECTIVE This longitudinal study investigated the relationship among early childhood caries (ECC), α amylase, carbonic anhydrase VI (CA VI), and the presence of visible biofilm, besides detecting if these variables could predict risk for ECC. METHODS One hundred children were divided into two

Salivary alpha-amylase, one of the most plentiful components in human saliva, has at least three distinct biological functions. The enzymatic activity of alpha-amylase undoubtedly plays a role in carbohydrate digestion. Amylase in solution binds with high affinity to a selected group of oral

Salivary alpha-amylase, a major component of human saliva, plays a role in the initial digestion of starch and may be involved in the colonization of bacteria involved in early dental plaque formation. The three-dimensional atomic structure of salivary amylase has been determined to understand the

Research has garnered support for a systemic view of factors affecting child dental caries that accounts for the influence of social factors such as the family environment. Our previous work has demonstrated the association between mother-to-father emotional aggression and child caries. The present

Peptidyl-prolyl isomerases (PPIases) are biologically very important enzymes but their catalytic mechanism is not fully understood. Recently, our comprehensive mutational study on a PPIase, human FK506-binding protein 12 (FKBP12), suggested that only presence of a cavity was required for the

Carbonic anhydrases maintain pH homeostasis in various tissues of the human body by catalyzing the reversible reaction CO2 + H2O <=> HCO3- + H+. Carbonic anhydrase isoenzyme VI (CA VI) is secreted into human saliva by the serous acinar cells of the parotid and submandibular glands. Although it

Thermoactinomyces vulgaris R-47 produces two alpha-amylases, TVAI and TVAII, differing in substrate specificity from each other. TVAI favors high-molecular-weight substrates like starch, and scarcely hydrolyzes cyclomaltooligosaccharides (cyclodextrins) with a small cavity. TVAII favors

OBJECTIVE The hypothesis of this study was that feeding glucose instead of sucrose in the cariogenic Diet 2000 to rats weaned at age 18 days would result in greater light/dark differences in feeding activity and secretion and storage of parotid salivary enzymes. METHODS Diet 2000 and a stock

Starch granule-surface proteins (SGSPs) and granule-channel proteins (SGCPs) are granule-associated proteins (SGAPs), which have been found to be distributed on the surface and channels of starch granules, respectively. To investigate the impacts of SGAPs on α-amylase hydrolysis of starch, SGCPs or

Salivary α-amylase (sAA) is responsible for the 'pre-digestion' of starch in the oral cavity and accounts for up to 50 % of salivary protein in human saliva. An accumulating body of literature suggests that sAA is of nutritional importance; however, it is still not clear how sAA is related to

OBJECTIVE Anxiety and stress are usually related to the dental treatment situation. The objective was to investigate salivary cortisol and alpha-amylase levels (salivary biomarkers) and heart rate in children undergoing a minor dental procedure (dental prophylaxis). METHODS In total, 31 children
