Background:Oral lichen planus (OLP) is considered as a potentially malignant disorder and vascular endothelial growth factor (VEGF) may play a key role in cancer development. The aim of this study was to compare serum and saliva VEGF among patients with OLP, oral squamous cell carcinoma (OSCC) and a healthy control group. Methods:A cross sectional study was pe...
The system composed by mucosa, saliva and denture is complex and dependent of many variables. The decreased or absent flow of saliva induces a high disconfort which has to be reduced by all means, this meaning use of artificial saliva and improvement of surface characteristics of the denture base material. We investigated five materials produced by classic tehnology (press-pack moulding + diffe...
OBJECTIVE To evaluate the influence of saliva contamination on the bond strength of metallic brackets bonded to enamel with hydrophilic resin composite. METHODS Eighty premolars were randomly divided into 4 groups (n = 20) according to bonding material and contamination: G1) bonded with Transbond XT with no saliva contamination, G2) bonded with Transbond XT with saliva contamination, G3) bond...
Amylase testing has been used as a presumptive test for crime scene saliva for over three decades, mainly to locate saliva stains on surfaces. We have developed a saliva screening application for crime scene trace swabs, utilising an amylase sensitive paper (Phadebas(®) Forensic Press test). Positive results were obtained for all tested dried saliva stains (0.5-32 μL) with high or intermediate ...
We studied the effects of tick saliva on cell migration, cell signaling, phagocytosis, and gene expression in the murine macrophage cell line, IC-21. Saliva increased both basal- and platelet-derived growth factor (PDGF)-stimulated migration in IC-21 cells. However, saliva did not affect PDGF-stimulated extracellular signal-regulated kinase (ERK) activity. Zymosan-mediated interleukin-1 recepto...
Ca2+-binding proteins in the watery saliva of Megoura viciae counteract Ca2+-dependent occlusion of sieve plates in Vicia faba and so prevent the shut-down of food supply in response to stylet penetration. The question arises whether this interaction between aphid saliva and sieve-element proteins is a universal phenomenon as inferred by the coincidence between sieve-tube occlusion and salivati...
Human saliva has great potential for clinical disease diagnostics. Constructing a comprehensive catalogue of saliva proteins using proteomic approaches is a necessary first step to identifying potential protein biomarkers of disease. However, because of the challenge presented in cataloguing saliva proteins with widely varying abundance, new proteomic approaches are needed. To this end, we used...
We measured the concentrations of phenobarbital, phenytoin, primidone, ethosuximide, antipyrine, and caffeine in paired samples of saliva and plasma by gas chromatograph-mass spectrometer-computer (GC/MS/COM) and enzyme immunoassay. Mixed saliva was collected for the antipyrine and caffeine studies, parotid saliva for the phenobarbital, primidone, ethosuximide and phenytoin studies. The saliva/...
introduction: tobacco smoke is involved in the pathogenesis of several diseases in different body systems. saliva is the first body fluid that confront inhaled cigarette smoke which is injurious to the oral cavity and is associated with several oral diseases and cancer. the aim of our study was to evaluate the influence of smoking on the activity of alpha-amylase in the saliva of healthy smoker...
background and aims. lysozyme and lactoferrin are salivary proteins which play an important role in innate defense mechanisms against bacteria. this study investigated the association of salivary lysozyme and lactoferrin concentrations with early childhood caries (ecc). materials and methods. this study was carried out on 42 healthy children (age range, 36 to 71 months), of whom 21 were caries ...
