Leukocyte esterase and protein levels in saliva, as indicators of gingival and periodontal diseases in children

Abstract

This study was to determine if dip stick assays of children's saliva for leukocyte esterase or protein (Serim Research Corporation, Elkhart, Ind) reflect the presence or severity of gingival or periodontal diseases in children. The study included 13 children with periodontitis [study group] and a control group of 17 children without periodontitis. The saliva leukocyte esterase and protein values (scales from 1 to 4) were tested with dip stick analyses. The gingival (GI) and plaque indices (PI) presence and number of sites with periodontitis, demographic data, systemic condition, caries prevalence, and the presence of dental restorations were recorded and their relationship to leukocyte esterase or protein values were analyzed. Most children had a protein value of 2 or 3 or a leukocyte esterase value of > or = 3. Significant differences in the distribution of protein values by the presence/absence of periodontitis (chi-square, P<0.001), or the number of sites with periodontitis by protein value (chi-square, P=.005; ANOVA, P=.03) were evident; No. 4 protein values were found only in children with periodontitis, and No. 2 and No. 3 protein values were mostly found in children without it. Dip stick protein analysis of saliva of chi...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
